Introduction

• 4 door model is part of all-new seventh generation, global Civic range
• Innovative 'short nose' design contributes to class-leading interior space
• Flat floor for greater comfort
• New 1.4 SOHC and 1.6 SOHC VTEC-II engines
• Fuel economy and low to mid-range torque boosted
• All-new front and rear suspension
• Best build quality yet

Blending strong dynamic performance, compact dimensions and an open, airy interior, Honda's latest Civic 4 door saloon is part of a powerful all-new line-up that builds on the strengths of the company's most successful range of cars in Europe. 

 

Highly innovative packaging means that inside the Civic is one of the most spacious cars in its class and together with distinctive styling outside, and a whole range of enhancements to performance, safety and build quality, stakes a very strong claim to leadership among C-segment contenders.

 

All the traditional Civic qualities of reliability, comfort, outstanding safety, economical operation and a fun-to-drive nature are retained. But it is completely re-engineered in every aspect using, in true Honda fashion, a whole host of advanced technologies, all packaged in a fresh and appealing design.

 

Short nose concept plus flat floor

In creating a Civic replacement the challenge was to provide a larger interior while retaining its compact nature and nimble handling. The new Civic 4 door is slightly shorter, slightly wider and taller than its predecessor. Yet it offers substantially more spacious interior accommodation, reflecting the all-new, designed from the inside-out, concept of the car.

 

Clever packaging is the key. At the front there is a new compact toe control link MacPherson strut front suspension, a high-mounted steering gearbox and a more compact engine bay. This in turn has enabled the front overhang to be reduced as part of a 'short nose' design concept which has the effect of freeing up more space for occupants and luggage. 

 

At the rear a more compact reactive link double wishbone suspension combined with clever underfloor packaging - including a resin fuel tank moulded to fill the space available - has allowed a flat cabin floor without any central tunnel. 

 

Class-leading interior space

The result is a range of interior dimensions that surpass competitor models. A key indicator of a car's spaciousness is the tandem distance, that is the distance between the hip points of front and rear passengers; in the Civic 4 door this is 811mm, 26mm greater than the previous model. Together with the flat floor, the effect of which is to substantially improve rear seat comfort and allow unobstructed movement from one side to the other, the light, airy interior offers passengers a particularly pleasant environment in which to travel.

 

In terms of exterior styling, clean, balanced lines impart a strong sense of solidity and refinement. A distinctive front end is characterised by the short nose and monoform design elements. The arching roof line delineates a large glass area that ensures excellent visibility and although height has been slightly increased, visually this is not excessive.

 

Innovative solutions in the quest for safety

A primary design objective was the accomplishment of outstanding levels of impact safety, together with pedestrian safety performance. The 'short nose' design was a true engineering challenge in this context, but the Civic's ingenious solution is to effectively split the impact energy along two parallel paths: the high stiffness front side members and the sub-frame beneath, providing impressive energy absorbing characteristics.

 

Elsewhere in the bodyshell there is extensive stiffening and use of high strength steel to provide an extremely strong structure. Overall body rigidity is also increased for better NVH and suspension refinement.

 

Luggage capacity up too

The Civic 4 door is more versatile than ever and boot capacity is increased to 450 litres (VDA); together with a wide-opening boot lid, a width of 1050 mm between the rear suspension pillars (up 142 mm) and a boot aperture increased by 40 mm front to rear, it makes for outstanding load carrying ability.

 

The relaxing, spacious cabin offers exceptional refinement. Extensive use of noise suppression materials, careful coordination of colours and textures, larger front seats and accommodation increased in all dimensions, combine with a more supple ride to make travel in the Civic a particularly pleasant experience.

 

Superb fit and finish

One of the most tangible indications of the new Civic's enhanced quality are the extremely close tolerances accomplished with the body panels, achieved in large part through new and advanced manufacturing techniques. In most cases the gaps have been halved, in some cases reduced almost to zero, greatly improving the fit and finish appearance. Attention to detail is apparent everywhere, including the interior where flush surfaces and reduced gaps for superior fit and finish, plus a higher grade of materials impart an air of high quality.

 

Refinement mirrors this build quality and NVH characteristics have been targetted in all areas. Engine noise under acceleration, for example, is reduced by 3 dB(A) and the Civic benefits from a raft of measures including sophisticated engine mountings, high body rigidity and extensive use of melt sheeting, rubber mat insulators and urethane foam. 

 

1.4 and 1.6 litre engines offer sophisticated engineering solutions

Power is provided by two highly efficient, aluminium alloy based 16-valve engines which have been engineered for greater torque and therefore driving flexibility. They are also more refined, more economical and cleaner. The smaller, 1.4 litre SOHC engine produces a similar 90 PS (66 kW) to its predecessor, albeit at a lower 5,600 rpm, but torque is boosted from 126 Nm at 4,600 rpm to 130 Nm at 4,300 rpm.

 

Similarly, torque from the 110 PS (81 kW) 1.6 litre SOHC VTEC engine is now 152 Nm at 4,300, up from the 143 Nm at 4,800 rpm of the 1.6 litre SOHC engine of the previous Civic 5 door. Together with an aerodynamically efficient body, this translates into sparkling performance figures and fuel consumption better by some 10 per cent.

 

Manual and automatic for all models

Both engines can be matched to either 5-speed manual or 4-speed automatic transmissions. The electronically controlled automatic, with extended torque converter lock-up for greater economy, provides more precise shifting and incorporates Grade Logic, the intelligent ratio selecting system. The manual transmission has been designed for shorter, more precise shifting.

 

Front and rear suspensions are all-new for an enhanced, supple ride and sportier handling, plus the packaging benefits already described. Toe control link MacPherson struts have been selected for the front suspension, while at the rear a new reactive link double wishbone set-up provides rear wheel toe-in under braking for greater stability. Ride comfort has been improved by reducing the spring rates of the front and rear compliance bushings while suspension rigidity generally is increased for better control and stability.

 

A high-mounted steering gearbox not only provides packaging benefits; the long tie-rods that result allow improved toe control. Indeed the toe characteristics of the toe control link MacPherson strut front suspension are more akin to those of a double wishbone design. A better balance between front and rear roll centres, an increased steering gear ratio and more linear steering response provide the Civic driver with an outstanding level of control and feel. 

 

Electric Power Steering (EPS)

The Civic becomes Honda's first volume model in Europe to feature Electric Power Steering (EPS) with all its attendant benefits including enhanced fuel economy, programming flexibility and smoother operation. Similar to the system in the Honda Insight, the gearbox is mounted in a high, central position and the long tie-rods that result allow improved toe control; indeed the toe characteristics of the toe control link MacPherson strut front suspension are more akin to those of a double wishbone design. A better balance between front and rear roll centres, a modified steering gear ratio and more linear steering response provide the Civic driver with an outstanding level of control and feel. 

 

The new Civic offers a high level of recyclability and as a further indication of Honda's progress in this area, most plastics used in the interior can be reprocessed and reused.

The new global Civic range

The new 4 door model is part of a brand-new family of Civics being introduced to the market in a phased programme during the next 12 months. The Civic 2 door Coupe will go on sale in selected European markets at the end of this year, and following the commencement of 5 door sales in early 2001, the new  3 door model will appear in European showrooms in autumn 2001.

 

The Civic is a truly global car: all variants share the same platform and the same basic specifications, although 2 door and 4 door models have a 60 mm shorter wheelbase. Both the 3 and 5 door models will be built at Honda's Swindon, UK plant. Honda's Japanese facilities will build 4 and 5 door models, while the US will supply the 4 door saloon and - uniquely - the 2 door Coupe.

 

New Manufacturing System

The Civic is the first Honda to be launched simultaneously around the world and to ensure a consistent level of quality among the various manufacturing facilities, the company established the New Model Center in Tochigi Japan. From the earliest stages of development, manufacturing associates from Civic plants gathered there to provide critical input and the Center has used this information to formulate best build practices. The latest Civic is also the first global model to be built using Honda's New Manufacturing System which employs highly flexible welding robots and standardised assembly line layouts to reduce investment in new tooling.

 

Part of the development and manufacturing campaign has been a programme called 'Improving Quality 10 Times' or 'Q10' in which the goal has been to maximise quality gains in every aspect of the new Civic range - from the initial designs through to the final manufacturing process. This is most clearly illustrated by the excellent body fit and finish.

 

Product concept

From the very earliest development stages Honda has sought to infuse the new Civic 4 door with a range of abilities and a level of quality that would place it firmly at the forefront of the C-segment.

 

That meant retaining its traditional values of dependability and practicality while enhancing levels of comfort and refinement, handling and performance and above all added versatility through increased interior space. Finally it needed to project fresh, contemporary styling.

 

Honda's customer research revealed that while customers of the outgoing model found the car useful in everyday life, for some the interior was considered too small for a young family. Nevertheless, they were satisfied by the Civic's handling, its sporty style, and its compact external dimensions.

 

Conversely, many considered the range of estates and MPVs on the market as being too 'bus like', too blatantly family cars lacking in sporting image; yet they approved of their spacious open interiors, with easy egress and ingress.

 

Honda therefore worked to address these issues by significantly increasing interior accommodation without compromising the Civic's compact car strengths or resorting to an increased 'footprint' - indeed overall length is reduced. In effect, the aim was to blend the good handling and performance exhibited by the outgoing Civic range with more space and practicality. The result is a new range of C-segment contenders with compact external dimensions and a large, spacious cabin for comfortable, economical motoring.

 

The Civic 4 door is aimed at 35-45 year-olds with a young family or those thinking of starting one, together with empty nesters in their late forties and fifties.

 

The marketplace

Honda's new C-segment contender is particularly significant in that, following the launch of the current Accord range, it represents the second phase in a strategy aimed at boosting the company's presence in Europe's high-volume market sectors.

 

To put this into context, the C-segment was firmly in pole position within the European car market during 1999, with sales of 4.8 million units equivalent to a 32 per cent share of the total. Furthermore, the out-going Civic range in all its derivatives represented 42 per cent of the company's European sales in the same year (5 door 18 per cent; 3 door 13 per cent; Aero deck 6 per cent; 4 door 4 per cent; Coupe 1 per cent).

 

The new Civic 4 door model enters a sub-division of the C-segment that has remained fairly static over recent years and during 1999 accounted for 9 per cent of total C-segment sales. 

 

A brief history

The story of the phenomenally successful Civic range, justifiably ranked among the world's most successful car product lines, stretches over a period of almost 29 years culminating in today's launch of what is the seventh generation of Civic. 

 

The debut of the Civic brand in July 1972 represented Honda's first 'mainstream' car, and signalled the company's arrival among the ranks of the world's leading car manufacturers. It has since played an important role in establishing the key attributes Honda vehicles have become known for: dependability, quality, reliability, and efficiency. The Civic has been Honda's best-selling vehicle around the world for more than 20 years.

 

The first Civic was a small, unpretentious, front-wheel drive hatchback and one of the first Japanese cars regarded as competitive against European contenders. Power was provided by a series of transverse four cylinder engines ranging from a 54 bhp 1169cc unit to a 75 bhp 1488 cc unit.

 

Successive generations underwent progressive enlargement and benefited from enhanced specification and by the mid-1980s the Civic was quickly gaining a reputation for outstanding build quality. In the US the Civic's environmental credentials were established when the CVCC-engined model became the first vehicle, in 1975, to meet the Clean Air Act without the need for a catalytic converter, something most manufacturers said couldn't be accomplished.

 

Bigger and better engines eventually led in 1987 to the fourth generation Civic which boasted of four-valves-per-cylinder across the range plus the introduction of VTEC technology, bringing sophisticated engineering to the compact class; body variants included the tall estate-car style called the Shuttle and the CRX sports coupe.   

 

By May 1995, the ten millionth - a fifth generation - Civic had emerged from the production line at Honda's Suzuka plant. The 1996 model year Civic became the first petrol-powered car to meet California's Low Emission Vehicle (LEV) standard. Significant from a European perspective, a new 5 door model became the first Civic to be built at the Swindon, UK plant.

 

The current sixth generation has grown to become one of the most comprehensive on the market with a choice of 2 door coupe, 3 door and 5 door models, 4 door saloon and 5 door Aero deck being produced from 3 different countries, Japan (3 door and 4 door), USA (2 door) and the UK (5 door and Aero deck).

 

 

Body

• Shorter, taller and wider overall 
• Same wheelbase retained
• Short nose is key design element
• Fresh, distinctive styling with sense of solidity
• 'Smart Linked' body structure achieves outstanding crash performance
• Pedestrian safety a major consideration
• Highly rigid body boosts NVH, handling and safety
• 57 per cent of bodyshell by weight is high-strength steel
• Extensive noise suppression measures
• Body fit and finish improved still further
• High level of anti-theft equipment

In the Civic 4 door Honda has met its primary objectives of enhanced safety, even tighter fit and finish, and reduced NVH in a design that is both attractive and distinctive while offering outstanding interior space.

 

A look of distinction

The fresh, balanced styling of the Civic 4 door imparts an air of sophisticated solidity and refinement. Like the 5 door model, a short nose and steeply raked windscreen with its base moved closer to the front wheels give the Civic 4 door a distinct monoform look. However, the 4 door saloon shares its frontal styling with the 2 door Coupe rather than the Civic 5 door.

 

In the 4 door model the lines of the distinctive two-blade grille with chrome trim along its top edge, blend smoothly into bonnet creases that flow back towards the A-pillars. The bright, jewel-like headlamps, featuring free form and multi-reflector technology, have parking lights positioned towards their base in contrast to those in the 5 door where they are mounted towards the top of the housing.

 

Although there are familiar design cues recurring throughout the whole Civic range, each body style has its own distinct features, and the 4 door saloon is no exception. From the A-pillar back, its styling is unique - indeed only 22 per cent of sheet metal body panels are common to both the saloon and the 2 door Coupe.

 

An overall dynamic quality is provided by the continuation of the front wing profile back along the car in the form of a shoulder. This strong character line, passing through the door handles and flowing all the way to the taillights, imparts a solid, upmarket appearance. A second, more subtle crease at hip point level runs parallel to it and between the wheelarches. A black B-pillar creates a cohesive look to the side profile.

 

The raked angle of the rear screen, mirroring that at the front, flows into a relatively high deck. The rear light housings are equally high mounted and the boot shutline splits them so that the reversing light and taillight are contained within the boot lid.

Exterior dimensions

 

Behind the Short Nose

The new Civic 4 door saloon is very slightly shorter, 50 mm taller and 20mm wider than its predecessor. Significantly, the wheelbase remains the same at 2620 mm, and while front overhang is substantially reduced, the rear overhang is increased 40 mm for greater luggage capacity. It is this aspect of the front wheels being 'pushed' forwards, together with what Honda calls its 'short nose' concept that have a major bearing on interior accommodation.

 

Visually, the short nose - 65 mm less than its predecessor and with the base of the windscreen raked 50 mm closer to the front wheels - is a key styling element; it is also an eminently practical feature since it frees up more space that can be devoted to interior accommodation. The design has been made possible by the compact nature of the front suspension and the adoption of a high mounted steering gearbox, which in turn have allowed the repositioning of the engine within the engine bay for better space utilisation. Despite the reduced nose dimensions, the Civic offers outstanding crash safety characteristics.

 

Extensive use has been made of computer simulations for more efficient and cost-effective development of the body. As well as reducing development time, these techniques have allowed the engineers to minimise weight and determine the optimum materials while improving the overall design. One of the benefits to emerge from this process is a significant improvement in body rigidity. Torsional rigidity has been increased by 47 per cent, while bending stiffness is up by 2 per cent, which not only offers improved impact resistance, but also aids handling and ride by ensuring that the suspension mounting points always remain in correct alignment, and reduces interior noise levels by limiting body-panel resonance. 

 

The Civic 4 door bodyshell is aerodynamically efficient. The designers used a computer-generated 'virtual wind tunnel' to predict wind flow around the car and every aspect of the body was studied to reduce drag and minimise wind noise. This included developing the general shape of the body, refining the front spoiler, adding a rear suspension cover, even refining the shape of the rearview mirrors.

 

Ingenious underfloor packaging

One of the notable features of the Civic is its flat floor which provides a more comfortable environment, particularly for rear seat passengers. This has been achieved by clever underfloor packaging whereby the compact reactive link double wishbone rear suspension (see Chassis section) together with the adoption of a new plastic petrol tank allows the exhaust pre-chamber to be repositioned.

 

The 50 litre lightweight tank uses four different types of resin in six layers, and the fact that it can be moulded in an infinite variety of shapes, means that it can make the most effective use of the space available.  By locating two silencers towards the rear of the car - rather than siting one pre-chamber midway along the exhaust - the floor can remain flat and in an ingenious piece of packaging, the smaller, high efficiency exhaust pre-chamber is placed between the tank and the suspension. This positioning has also improved rear ground clearance by 24 mm in the fully laden state. The larger final chamber is tucked behind the rear valance.   

 

Crash safety

The new Civic 4 door features an impact-resistant passenger cell, precisely calculated deformation zones, a number of innovative items designed to minimise pedestrian injury, and a complete all-round safety package for occupants. In turn, passive safety features are complemented by the advanced active safety features of the Civic design: safe, predictable handling, powerful braking with ABS and electronic brake force distribution, and precision steering.

 

Smart-Linked body

Behind the Civic's impressive crash performance is what Honda calls its 'Smart Linked' body structure technology. This refers to the way in which the size and cross-section of crossmembers and the way in which they link to the frame rails and side-sills has been optimised to achieve major increases in bodyshell stiffness; the effectiveness of each individual joint is amplified in this way.

 

The safety levels achieved are all the more impressive given two particular design features of the new Civic: first the short nose, and secondly the lack of a central tunnel in the flat floor, both of which have provided a greater challenge in managing impact energy and the need for some innovative solutions. 

 

Controlled G-forces

Employing Honda's progressive deformation technology has allowed the controlled collapse of the front side frame on impact, and more effective management of the G-forces exerted on occupants. Unlike conventional front end structures, the Civic's has two parallel paths along which frontal crash energy is absorbed: the front side frame and, beneath them and working in concert, the sub-frame. Energy is then channelled into the floor rails and the centre frame to efficiently disperse energy. Compared with the previous Civic, the initial G forces are configured  so that more of the energy is absorbed during the early stages of the impact cycle, which means that peak force can be more effectively managed to minimise any injury to occupants.

 

Body reinforcement

For additional side impact protection, the Civic features larger high-strength steel front and middle cross members. In terms of rear impact protection, the new rear suspension design has allowed for a straighter rear frame, and together with a more rigid connection between the side sill and rear side frame, impact absorption characteristics have been considerably enhanced.

 

Key features contributing towards the extremely tough passenger safety cell include:

• reinforced links between the rear floor structure and sills and the rear frame
• an additional cross member in the rear boot floor 
• a stiffener added to the base of the A-pillar where it meets the front floor 
• a stiffener added where the rear side arm joins the boot surround
• a large cross member across the floor and beneath the rear seat
• a reinforced link between the front bulkhead and floor

Compared to a conventional floorpan, an additional longitudinal floor rail was added and the front centre crossmember made stronger as a consequence of the flat floor design.

 

Extensive use of high-strength steel

To provide a high degree of strength without any associated weight penalty, 57 per cent of the bodyshell by weight is made from high-strength steel, including the side frame and floor structure forward of the rear wheel house, the roof arch, the front sub-frame and the front and rear bumper beams.

 

Comprehensive safety equipment

As part of the comprehensive safety package, all Civics are fitted with both driver and front passenger airbags and in many markets front seat occupants also benefit from side airbags for even greater protection in the event of an accident.

SRS front and side airbag deployment

 

Front seatbelts feature pre-tensioners with load limiters, and all three rear seats feature three-point inertia-reel seatbelts.  Front seatbelt upper anchors are height adjustable.

 

In addition, the interior trim incorporates a number of small detail safety items designed to reduce the risk of occupant injury in the event of an accident, including roof rail and window pillar trim with an impact absorbing structure for controlled deformation.

 

In the event of the car turning over in an accident, a special fuel system shut-off valve is activated to prevent spillage.

 

Targetting pedestrian safety

A key component of Honda's extensive research into pedestrian safety through accident avoidance and injury reduction has been the development of a safety research prototype vehicle, the ASV3, within the ASV (Active Safety Vehicle) project under the guidance of the Japanese Ministry of Transportation. The use of increasingly sophisticated pedestrian dummies, extensive road accident analysis and a computer-assisted accident simulation programme are providing invaluable data towards identifying and minimising the potential for injuries.

 

Specific items on the Civic aimed at minimising pedestrian injury include:

• an unobstructed area beneath the bonnet which allows it to deform on impact
• bonnet hinges that compress under impact
• energy absorbing wiper designed to break under impact

As part of the objective of driving down insurance and repair costs, Honda engineers focused their attention on reducing the damage that occurs in low-speed, under 5 mph accidents, which can result in very high repair costs. As a result, the new Civic is designed to minimise headlight and boot lid damage in this type of accident.

 

NVH performance

For the new Civic, Honda has placed considerable emphasis on securing the kind of levels of refinement more normally associated with larger cars. NVH performance is considerably improved by increased body rigidity, more extensive application of sound absorbing material, a reduction in idling vibration, low road tyre noise and comprehensive sealing of all holes in the body structure.

 

Among the numerous measures adopted to prevent external noise from intruding into the cabin are:

• urethane foam inside lower front pillar
• sound absorbing roof lining with felt.
• boot mat and side lining backing felt
• the lower A-pillar has a foam infill
• floor carpet with high performance PET felt backing - 15 mm thick with a weight of 1.8 kg/m²
• urethane foam fascia insulator
• fascia undercover has Thinsulate layer (26 mm thick on the driver's side, 13 mm on the passenger's side)
• bonnet insulator (1.6 only)

Additionally there has been an increased application of anti-vibration melt sheet. This asphalt insulation material is literally 'melted' into place to ensure a precise fit:

• foamed melt sheet on floor
• melt sheet on floor aft of seats
• melt sheet around spare wheel well
• melt sheet around rear wheel housings

Engine mount system

A sophisticated engine mounting system plays a large part in suppressing the transfer of noise and vibration to the interior space. The Civic has four mounts, two fixed and two liquid-filled, attached to the cradle-type sub-frame. Centrally mounted at the front of the engine bay is a lightweight extruded aluminium mount, while at the rear a second fixed bracket is made from resin which shears in the event of an impact, so limiting rearward movement of the engine and ensuring that it does not compromise the action of the crumple zone structure.

 

The two high-performance liquid-filled mounts attached to either side of the sub-frame - one for the transmission, the other for the engine - are slightly offset.  This is because they are located along the axis of the engine's principal inertial moment (the axis about which the engine vibrates) and at these points, the least amplitude of engine vibration is transmitted from engine to frame, which significantly reduces engine-idle vibration. Together with the excellent absorption properties of the liquid-filled mounts, it means that engine noise and vibration are particularly well damped so adding to the general air of refinement within the Civic's cabin. 

 

The engines themselves have received a number of enhancements to mitigate noise generation including a redesigned induction manifold for reduced induction noise, greater cylinder block rigidity and the addition of a timing belt automatic tensioner.

 

During acceleration, engine noise entering the cabin has been reduced by 3 dB(A) and road noise by 2.5 dB(A).

 

Hydro-formed sub-frame

The sub-frame itself - dubbed a shark's jaw by Honda engineers because of its unique shape - is made using a newly developed hydro-forming manufacturing technique. This makes it lighter and more rigid and is the first application of hydro-forming on a Honda vehicle.

 

The process involves a steel tube, one end of which is crimped, being placed in a die. Water, under extremely high pressure, is fed into the tube, forcing the tube to adopt the precise shape of the die. The resulting component is lighter than a comparable cast or machined component. 

 

Fit and finish

The excellent NVH characteristics attained by the Civic are mirrored in the level of exterior and interior build quality. Careful analysis of the build process, as part of the 'Q10' development and manufacturing campaign, resulted in the adoption of new manufacturing techniques (more details are provided within the Production section). These have brought increased body accuracy, evident in smaller panel gaps and in the improved door, boot and bonnet clearances, which are all the more significant given that Honda vehicles have long been synonymous with outstanding fit and finish.

 

As an example of what has been achieved, the new Civic features what is known as a '0' gap for the front and rear bumpers, or less than a single millimetre. This gives the bumpers a more integrated appearance.

 

Examples of other reductions are:

• rear light housing to body gap reduced from 3 mm to 0.5-1 mm
• headlight housing/bonnet from 6.5 to 3 mm
• headlight housing/front bumper from 3 to 1 mm
• headlight housing/front wing from 3 to 1 mm
• front wing/bonnet from 4 to 3 mm
• front wing/bumper from 3 to 0.5 mm
• door/body gap from 5.0-5.5 to 3.5-4.0 mm.
• fuel lid/body gap from 4 to 3 mm

Similarly, there has been a comprehensive reduction in the corner radii of many body panels to enhance the sense of a neater, fully integrated design with an overall air of solidity.

 

Extensive anti-theft measures including standard rolling code immobiliser

A series of theft-deterrent measures have been incorporated into the Civic 4 door including a standard equipment rolling code immobiliser from which it is virtually impossible for thieves to clone the entry code.

 

The ignition key features a built-in transponder, which, when removed, immobilises the engine fuel injection and ignition so the engine cannot be started. When the key is reinserted and turned in the ignition, the transponder in the key transmits a code via an antenna built into the steering lock surround to the engine management computer. If the code, which changes each time the key is removed from the ignition lock, is confirmed by the engine ECU, the engine will start - but only then. The immobiliser multiplex control unit, engine ECU and ignition key/ignition barrel transponder are all linked via a bus communication.

 

All models feature central locking (with the exception of S specification models in some markets) with a remote keyless system that uses FM radio waves, rather than AM, for more effective operation.

 

Other security features provided as standard  include:

• immobiliser sticker on driver's window
• lock knob flush with door interior
• visible VIN
• immobiliser
• front and rear door handle protectors
• door lock protectors
• key rod protector on driver's door
• dead locks and boot handle protector 

According to grade, the following features are provided:

• alarm
• radio security
• alloy wheel locks

Door lock and rod protectors are designed to deflect attacks where 'slim jim' type mechanisms are slid between the door and the side window glass to gain entry.

 

Where an alarm is fitted, it is activated upon the first locking action and deactivated as the doors are unlocked.

 

 

Interior

• Class-leading accommodation for both passengers and luggage
• Totally flat floor
• High quality panel fit and finish
• Comfort and ergonomics enhanced throughout

Thanks to the innovative packaging of the overall design, including the short nose concept, compact suspension and the underfloor arrangement of the rear exhaust and petrol tank, the Civic offers outstanding interior accommodation for a C-segment contender. Indeed, in all major interior dimensions the Civic is larger than its main competitors.

 

While the car's overall height points to the ample headroom available, the length of the Civic 4 door gives little clue to the outstanding space for occupants both front and rear. Rear legroom, for example, has risen by 48 mm to 915 mm.

 

Easy entry and exit

Raised hip points front and rear make climbing into and exiting from the Civic a particularly comfortable process. That at the front has been increased by 25 mm, and that in the rear is raised by 20 mm.

 

Flat floor enhances interior space

A totally flat floor, without the typical tunnel that runs the length of the interior, adds to the sense of spaciousness, particularly in terms of rear seat foot room. This has been made possible by the clever underfloor packaging (see Body section) with a resin petrol tank moulded to the most effective shape in terms of space utilisation together with a compact exhaust system that runs alongside it.

 

Flush surfaces, high quality materials

In selecting the interior materials, fixtures and fittings, Honda has aimed for a high level of refinement and quality. Careful attention has been paid to panel fit and finish, resulting in substantially reduced gaps and the application of flush panel joints and concealed fasteners wherever possible. The housings of the interior door handles are flush with the surrounding trim, for example, which although relatively minor detailing, can, of course, have a profound influence on a passenger's overall perception of the car.  Other examples are:

• flush joints between the window pillars and the roof lining
• flush interior light
• flush trim joints around the floor sills
• flush sunroof
• elimination of the gap between the A-pillar and the fascia
• retracting grab handles with damping mechanism

The sunroof now features an aluminium sunshade and uses a much thinner motor, to give a higher level of rigidity and the liberation of over 25 mm of extra headroom. High quality materials have been selected for cabin trim and seat fabrics. The window pillar trim for example features a grained finish with a marble look achieved by mixing dedicated pigment fibre into the master colouring batch; the result is an almost fabric-like appearance, similar to the roof lining. The top of the dashboard has a distinctive textured finish.

 

At the controls

Naturally, all aspects of driver ergonomics have undergone careful analysis to ensure as pleasurable a driving experience as possible. Steering inputs, pedal pressures, and the operation of controls generally have been analysed to ensure they function smoothly, progressively and above all predictably. The driver's view of the controls and instruments is direct and unobstructed, while their layout is logical.

 

The main display features four circular dials, with illuminated white needles, which are increased in diameter and feature larger white numbers on a black background, for better legibility. A large tachometer (on the left) and speedometer are flanked by a smaller temperature gauge (on the left) and a fuel gauge. The fuel gauge is a CPU-controlled unit which gives a linear response throughout the range of the tank and minimises needle vibrations. The lower portion of the speedo houses an LCD odometer/twin trip meter and (on ES grade) an outside temperature gauge reading from -30 to +45 C.

The Civic 4 door's fascia

Compared to the previous Civic, there are a number of changes to the steering column stalks for easier operation. Instead of a rotary operation, the right hand wiper control now works in a vertical direction, while the left hand indicator stalk also incorporates the lighting controls with the outermost rotary element controlling parking and dipped beam, the inner rotary element the rear fog lamps. Moving the stalk forwards operates the main beam, moving it backwards operates the flick mainbeam. The power window switches in the door armrests, the remote control mirror switch on the fascia, the heater, audio, and hazard warning light switches are all illuminated. An internal fuel filler release and boot lid release are provided on the floor alongside the driver's seat.

 

The heater controls and audio system are mounted on the central fascia. There are two DIN standard apertures with a flush surface design allowing a wide range of alternative ICE units to be fitted. If unused, one of the two apertures provides an additional storage area.

 

The automatic transmission features a new 'cobra' type select lever, so-called because of its shape. This is significantly narrower and positioned 26 mm closer to the driver for greater ease of use. It is also fitted with a release button which is operated by a vertical push of the finger rather than a horizontal movement, so reducing the risk of inadvertent shifting.

 

Sitting comfortably

Particular attention has been paid to minimising fatigue during long periods of driving. The totally new front seats offer superb occupant support with cushion width increased by 25 mm, wider springs and a urethane foam that has been specially selected for its high damping properties to minimise bounce and vibration.

 

Similarly, the seat backs feature a large side frame together with 20 mm larger side bolsters made up of several urethane foam types of varying hardness. Included in the Civic's standard specification are a height adjustable steering wheel and driver's seat height adjustment enabling the driving position to be fine-tuned to suit individual preferences. ES models include an integrated driver's armrest which has been redesigned to make its location more comfortable for the driver without interfering with access to the centre console.

 

A significantly larger footrest - 90 mm longer and 35 mm wider - is provided for the driver's left foot for greater comfort on long drives.

 

Luggage swallowed with ease

At 450 litres, the new Civic 4 door boot offers an extra 40 litres of load space (VDA) matching exceptional interior accommodation with impressive load swallowing ability. A particularly compact rear suspension design (see Chassis section) means that the loading width between the suspension pillars is 1050 mm, an increase of 142 mm over the previous Civic.

 

Furthermore, the size of the boot aperture between the loading lip and the base of the rear windscreen is up by 40 mm to 450 mm. Together with a wide-opening boot lid and a low sill, the Civic 4 door saloon provides a particularly versatile and easy to use load area. The boot will can accommodate four 660 mm Samsonite suitcases (similar to the Accord) against the two of the previous model. For maximum versatility, the rear seat backs can be split 60:40

 

ISOFIX mountings

The rear seats have ISOFIX standard child seat mounting points, allowing the seat to be fitted more safely and easily without any problems of slipping or tilting. Arms protruding from the base of the child seat lock into anchor bars located between the rear seat back and the seat cushion, firmly attaching the seat to the car body. The top of the child seat is held firmly in place by means of a strap which attaches to a tether anchor behind the seat.

 

A place for everything

The new Civic is provided with a number of useful storage areas around the cabin. First, the glovebox capacity has been increased from 5.5 to 6 litres. There is a pocket below the radio that can accommodate three CDs. There's a convenient lower pocket in the centre console that is ideal for carrying sunglasses, and alongside the handbrake, a space that is handy for cigarettes, or a mobile phone, for example. The driver also has a flock-lined pocket for coins and other small items just beneath the air vent.

 

Ahead of the gearshift, in the centre console, are two cup holders, both of which will accommodate a large (500 ml) drinks bottle while still allowing access to the ashtray.  A useful touch is that one of the holders has a series of ridges - 67, 73 and 89 mm in diameter - which ensure cups of different sizes are held securely in place. ES models add a rear cupholder.

 

Finally, the front doors contain large storage bins.

 

New improved speakers are lighter in weight

The new Civic 4 door provides an enhanced acoustic experience. The two front speakers and two rear speakers (rear an option on S models, standard on LS and ES) are of a new design; the 17 cm neodymium units, housed in a resin frame are significantly lighter in weight resulting in a 1.32 kg saving per car, and simplified attachment to the door. The use of neodymium magnets also improves the acoustics with better low and high pass characteristics and a reduction in high harmonic distortion. Reception is provided by a glass antenna.

 

Cool improvement

The air conditioning system where fitted has been increased in efficiency by 17 per cent. Condenser performance is up 23 per cent, while fan noise is reduced by a significant 2dB(A). The pollen filter, which is able to trap particulates down to 0.3 microns, has also been designed for very easy servicing; it simply requires the glovebox to be swung forward and away from its housing to gain access, a process which does not require any tools.

 

Rear seat passengers are provided with their own floor-mounted heating ducts.

 

Dim the lights

With its convenient timed operation and dimming facility, the interior light is designed to provide a 'welcoming' introduction to Civic motoring. If the doors are unlocked with either the key or the keyless entry system, the interior light comes on at maximum intensity. It then remains on for 30 seconds after unlocking, for 3 minutes if the door is subsequently opened and for 6 seconds following closure of the door. However, if the doors are not shut properly, the light will remain on for 3 minutes providing the engine is not switched on. Conversely, when the ignition key is removed after driving, or when the doors are unlocked from inside the car, the light remains on for 10 seconds. Again, opening the door prompts the light to stay on for 3 minutes, but if shut in the meantime, it will be extinguished after 6 seconds. In all cases there is a gradual reduction in illumination towards the end of the timed period before the light is finally switched off.

 

 

Drivetrain

• Choice of 1.4 litre SOHC or 1.6 litre SOHC VTEC II
• Extra torque boosts performance
• Increased combustion efficiency, low friction and weight savings
• Engines comply with EU2000 legislation
• Choice of 5-speed manual or 4-speed automatic with Grade Logic Control

The Civic 4 door offers a choice of two aluminium alloy based four-cylinder petrol engines: a 90 PS (66 kW) 1.4 litre SOHC and a 110 PS (81 kW) 1.6 litre SOHC VTEC II. Rather than boosting maximum output, the engineers have sought improvements in mid-range torque, fuel consumption, refinement and reduced emissions.

1.4 litre SOHC power and torque curves

Better torque delivery has brought greater flexibility during everyday driving and helped improve economy. Compared to the engine it replaces, the new 1.4 litre produces the same power output - 90 PS - at a lower 5600 rpm rather than 6400 rpm; but torque is boosted from 126 Nm at 4600 rpm to 130 Nm at 4300 rpm. A flatter torque curve also means it pulls more strongly across the rev range, particularly between 2000 and 4000 rpm.

1.6 litre SOHC VTEC II power and torque curves

Similarly the peak torque of the 1.6 litre engine is up from 143 Nm at 4800 rpm to 152 Nm at 4300 rpm compared to the 1.6 SOHC engine of the previous model. Power output is 110 PS at 5800 rpm.

 

Fundamental to the improved engine characteristics are a number of measures aimed at boosting combustion performance. First, a new design of swirl intake port has optimised both vertical and horizontal vortices inside the cylinder ensuring excellent fuel distribution and thorough mixing for effective, stable and clean combustion. By ensuring more complete burning of the air-fuel mixture, a higher compression ratio has been made possible.

 

New fuel injector design

Small, 'four-port' fuel injectors are used in the new engines. Featuring four orifices, rather than the usual single nozzle, these are one third shorter than the conventional pintle-type design. They offer more efficient fuel atomisation for improved combustion, while the problem of fuel mist clinging to the port walls is also reduced. The result is a significant reduction - as much as 14 per cent - in the amount of unburned hydrocarbons passing into the exhaust gases.  In addition, all engines are equipped with "knock" sensors.

 

Boosted torque

Torque characteristics have been further improved by reducing the length of the conduit between the air intake and the intake manifold chamber by 84 per cent. This has realised optimum resonance characteristics and torque at 4000 rpm is increased by 4 per cent.

 

EGR

Exhaust gas recirculation - introducing a proportion of the exhaust gases back into the fuel-air mixture - is an additional feature of the new engines. Its effect is to lower combustion temperatures which has the effect of reducing the levels of oxides of nitrogen for a cleaner exhaust.

 

The VTEC approach to economy

At the heart of the Civic's 1.6 litre engine is Honda's renowned Variable Valve Timing and Lift Electronic Control (VTEC-II) system which so successfully provides volumetric efficiency at all engine speeds to achieve good low to mid-range torque and vivid top-end output, together with outstanding fuel economy.

1.6 litre SOHC VTEC II engine cutaway

Friction

Any means of reducing energy lost through friction is of vital importance in the quest for low fuel consumption and the Civic's engines employ some of the innovative technology seen in recently launched models such as the Honda S2000 and Insight. The piston skirts, for example, are shot-peened with small ceramic balls to give a special 'micro-dimple' surface which improves the retention of the oil film between the piston and the cylinder, reducing overall friction by approximately 2 per cent. The small end bearing width is reduced from 23 to 20 mm, and finally the 1.6 litre engine features roller type rocker arms first seen in the Honda S2000 and Insight, rather than plain metal bearings, to provide a further 5 per cent reduction in friction losses.

 

Emissions

Both engines significantly better the EU2000 emissions requirements.

A crucial element in meeting these tough emissions levels is to bring the catalytic converter up to its effective operating temperature as quickly as possible. This is achieved by retarding the ignition timing after engine start to help promote rapid warming, while the exhaust system is of the low heat mass type for the same purpose. The catalytic converter is of the close-coupled type which means it is located as close as possible to the exhaust manifold, thus increasing efficiency after a cold start.

 

Fast, effective performance is also provided by increasing the number of cells integrated into the catalyst substrate to 900 per square inch, which gives three times the surface area. EGR helps to reduce oxides of nitrogen and finally, the small fuel four-port injectors deliver more efficient atomisation leading to a reduction in HC emissions.

 

Returnless fuel supply

Up to one third of all vehicle emissions occur while the vehicle is parked. The new Civic is therefore equipped with a returnless fuel supply system that effectively seals the tank to reduce vapour loss.

 

Weight down by 10 per cent

Engine weight has been reduced by around 13 kg - or 10 per cent - through both material and construction changes. These include:

• plastic intake manifold saving 1.9 kg
• fabricated exhaust manifold 1.6 kg
• aluminium engine side mount 0.5 kg
• plastic fan shroud 0.5 kg
• aluminium ECU casing 0.2 kg
• 4-weight light crank 0.4 kg
• EPS 1.8 kg
• exhaust-pipe-integrated catalytic converter 2.2 kg
• PHC ignition system 1.0 kg
• compact intake resonator chamber 1.3 kg. 

Reduced dimensions

The engines are now more compact from front to rear, reduced by 42.5 mm from 617 to 574.5 mm. The better packaging results from the relocation of various ancillaries and the adoption of a more compact air intake system. Typically, the bulk of the air intake system is located on the car body rather than the engine, with the air-cleaner case assembly usually fixed to the inner wing area beneath the bonnet. With this new generation of engines, Honda has positioned the air cleaner over the intake manifold and the resonator chamber over the transmission.

 

Packaging also benefits from a new PHC ignition system which locates a small high-performing coil above each spark plug, improving combustion efficiency and allowing reduced external engine dimensions.

 

Apart from freeing up greater space for occupants without increasing vehicle length, the more compact nature of the engine means there is more space available for the impact absorbing structures of the bodyshell to work effectively.

 

Noise reduction

Engine noise during acceleration and while at idle has been reduced by 6dB (A). Among the noise-reduction measures are:

• an automatic tensioner for the timing belt assembly
• a narrower timing belt with reprofiled teeth
• a new equal-length intake manifold which has eliminated the air induction noise typical of systems with different length intake runners
• rigidity of the cylinder block walls increased to minimise piston knocking noise at idle
• larger and stronger engine mounting brackets for less vibration during acceleration
• crankshaft web thickness increased by 1.5 mm for increased crankshaft rigidity which translates into reduced noise and vibration during acceleration
• connecting rod bearings with a textured surface to better hold oil for consistent lubrication and a smoother running engine

Transmissions

All Civic 4 door models can be specified with either a 5-speed manual transmission or a 4-speed automatic with Grade Logic Control. Both are new designs.

 

Manual transmission

The manual transmission benefits from a number of detail enhancements which have reduced the effort required to change gear and at the same time improved feel. In particular, the detent shape of the shift fork has been refined for a light and precise action, while synchromesh capacity on first gear is boosted 20 per cent by using a carbon-impregnated synchroniser and on second gear by a double cone mechanism. Other refinements include the use of smaller, high capacity bearings and synchroniser sleeves with a shorter stroke for a lighter, more compact gearbox casing. Reverse gear is precision forged.

 

Beneficial from an environmental and fuel efficiency standpoint are a reduced oil capacity and, during the production process, a reduction in gear machining.

 

Automatic transmission with extended lock-up

The compact automatic transmission is a sophisticated, four-speed, electronic constant mesh unit. It features a torque converter lock-up which is operational over a greatly extended speed range, benefitting fuel economy by around 3 per cent.

 

Grade Logic Control

The new automatic transmission incorporates Grade Logic Control, an intelligent system that has already appeared in several other Honda models and which, unlike conventional automatics, offers seamless progress over variable road conditions, particularly hilly routes where it can provide the driver with the same degree of control as a manual transmission.

 

Its advantage lies in its ability to determine the actual driving situation by measuring throttle position, road speed, rates of deceleration and acceleration and brake pedal application and then, based on a series of stored shift maps, to select the appropriate shift points for second, third and fourth gears. Thus, when the Civic is being driven uphill, Grade Logic will sense a large throttle opening without any speed increase, and from this deduces that the vehicle is going uphill and how steep the grade is. It then chooses a shift map that will downshift and hold third or even second gear.

 

However, if it receives a closed throttle signal and a brake pedal activation signal, the system determines that the car is being driven downhill.  It then selects a shift map that will downshift and hold third or second gear to make use of engine braking. Similarly Grade Logic can use a rapid deceleration signal and a closed throttle to determine that the car is entering a tight bend; it then chooses a shift map that downshifts early for more responsive acceleration. The same set of inputs occurs in the abrupt braking followed by quick acceleration that often accompanies stop-and-go town driving, thus promoting smoother driving.

 

Lock-up linear solenoid

Other features of the automatic transmission include a long torsion damper spring around the outer circumference of the lock-up clutch disc which provides effective absorption of vibration and a reduction in surging; a dedicated lock-up linear solenoid to control the hydraulic pressure to the gear clutch packs, providing more progressive clutch engagement and faster, smoother shifting; and an electronic control that is programmed to minimise 'shift shock' during full or part throttle upshifts and downshifts.

 

 

Chassis

• Compact toe control link MacPherson strut front suspension aids engine packaging
• High-mount steering gearbox contributes to excellent toe control characteristics
• Compact reactive link double wishbone rear  suspension contributes to flat floor cabin
• High rigidity suspension components improve handling
• High body rigidity permits supple ride
• Electronic Power Steering (EBD)
• ABS and EBD braking standard

Honda has long enjoyed a reputation for fine-handling cars thanks to extensive use of advanced suspension technology. In the new Civic, the target of the engineers was to enhance that reputation while at the same time contributing to the requirement for a more spacious cabin. In this they have succeeded and the result is substantially increased interior accommodation together with the kind of precision driving experience that Civic owners have come to expect and demand: a smoother, supple ride with reduced body roll, linear steering, and a high degree of stability during directional change. 

 

Toe control link MacPherson strut front suspension

At the front, the choice was made to use a new toe control link MacPherson strut arrangement, together with a high-mounted steering box. The adoption of struts rather than a double wishbone design has allowed a more compact suspension: its dimensions are reduced by 56 mm longitudinally, while the engine bay width is increased by 80 mm compared to the previous Civic.

Toe Control Link MacPherson strut front suspension

 

High-mount steering gearbox

Together with a steering gearbox located 227 mm higher (which gives more space for the front sub-frame to deform in frontal impacts), it means the engine can be located further towards the rear of the engine bay, thus helping to achieve the 'short nose' design to free up more space for use within the cabin.

 

The position of the steering box means that the track rods are increased in length by 221 mm (or by 43 per cent) to provide improved toe control (the amount the tyres angle in towards or away from the body). The geometry is such that toe characteristics over the vertical travel of the wheel are more akin to those of a double wishbone arrangement and substantially improved in comparison to a conventional strut arrangement. The Civic's new front suspension moves from slight toe-out at full bump to slight toe-in at full rebound; whereas conventional struts move from substantial toe-out at full bump to almost neutral in the median position and back to substantial toe-out at full rebound. The result is far better tyre contact with the road.

 

Reactive link double wishbone

At the rear the aim was to minimise damper intrusion into the cabin, so maximising load space, without compromising handling or ride. A reactive link double wishbone design was selected, but one that is more compact than the previous Civic's.

Reactive link double wishbone rear suspension 

A significant feature is its toe-control arrangement which means that under braking, the rear wheels toe-in to provide exemplary stability.  As the car is braked, the brake force is transmitted through the suspension structure which causes the rear mounted toe control arm located at 90 degrees to the force to flex backwards. The slight movement of the suspension structure to the rear that results in turn acts on the compliance bushes that locate the lower wishbone to the chassis. Their compliance in a diagonal direction pulls the trailing arm into a toe-in direction.

The design of the rear suspension is such that the spring, damper and lower wishbone are moved further outboard, thus requiring less space than before. It means the boot width between the suspension towers is increased by 142 mm to 1050 mm for better load swallowing capability.

 

The location of the lower wishbone also allows the exhaust pre-chamber to be slotted between it and the fuel tank, which in turn permits a flat floor.

 

More rigid suspension components

Suspension effectiveness is improved significantly by the torsionally stiff body together with the use of more rigid suspension components. It means any sudden loads do not move the suspension away from its ideal alignment and tyre contact is therefore increased for greater stability.

 

The front sub-frame and body together form an extremely stable unit that functions as an excellent platform for the front suspension, as well as yielding a high degree of isolation from vibration. The rigidity of the front suspension lower and upper arm bushings is up by 210 and 375 per cent respectively, while at the rear trailing arm rigidity is up 10 per cent and the wheel bearing is up 40 per cent. Tyre-to-ground contact at the front is more or less comparable to the double wishbone design of the previous Civic, while at the rear it is increased by 31 per cent for greater stability, markedly improved handling and ride comfort.

 

Movement of the rear wheels on bump includes more rearward motion than on the previous Civic, giving a more supple ride quality.

 

Improved front to rear balance

There is also now a better balance between the front and rear roll centres, to provide less pitch angle, and more stable and precise and linear handling characteristics during cornering. The suspension roll centre is 85.7 mm above ground level at the front and 156.7 mm at the rear.

 

Wheels and tyres

The new Civic 4 door has 14 inch diameter wheels and tyres for improved comfort and handling (the 1.6i ES has 15 inch). The tyres also offer reduced rolling resistance for better fuel economy. S and LS grade models feature steel wheels with full trims, while ES models are equipped with 5-spoke alloy wheels.

 

Electric Power Steering (EPS)

Honda has long been a pioneer of the concept of electric power steering (EPS) and its wide-ranging benefits. It first appeared in the NSX sports car, is fitted to the Honda S2000 and most recently appeared in the Insight petrol-electric hybrid. Now Honda has introduced it to a high volume model for the first time in Europe and the arrangement is essentially similar to that used in the Insight, with track rods connected to a high-mounted, centre take-off rack.

 

A hydraulic power assisted system of course requires a pump driven off the engine which can sap power by as much as 5 PS as well as adversely affecting fuel economy; EPS only absorbs electrical energy when required and fuel consumption is improved by almost 2 or 3 per cent in the Civic as a result.

 

Other benefits of EPS include:

• compact dimensions (there is no need for a hydraulic pump and hoses), which allow more design freedom in terms of placement within the chassis
• reduced weight
• greater flexibility in programming steering feel at all speed ranges
• more responsive at high speed
• smoother operating
• torque steer, steering kickback and steering judder at high speeds and under braking are substantially reduced
• tramlining on worn roads and/or on slippery surfaces is reduced
• steering assistance is available even with a stalled engine

EPS in operation

A microprocessor-controlled DC electric motor works in conjunction with a rack and pinion steering gear, providing assistance to the pinion as it moves the rack. The microprocessor senses vehicle speed and steering torque and is programmed to vary boost accordingly.

 

With this latest system, Honda's aim has been to improve steering response and feel.  Increased rigidity has brought greater controllability (represented by steering effort versus system hysteresis (or lag) and improved straight line stability. On the road it translates into a crisp, linear action offering excellent precision and weight at high speeds, and low effort at parking speeds.

 

Standard equipment ABS plus EBD

As well as four-sensor, three-channel ABS, the new Civic has Electronic Brake force Distribution (EBD). The latter is able to measure small front and rear wheel speed differences to ensure exactly the right amount of braking effort is applied to the rear wheels, via the ABS actuator, whatever load the car is carrying and taking into account the load transfer during deceleration. This allows the full potential of the rear brakes to be realised and both reduces the risk of premature rear brake lock-up when braking from high speeds and offers a more consistent pedal-feel.

 

The brake pedal action has been re-engineered to provide greater braking force over a shorter pedal stroke for a more precise and more linear action.

 

The new Civic also has a brake assist system. This comprises of a master power device which increases the master power braking output under emergency braking conditions.

 

Environment

Honda has made great strides in recent years in reducing the environmental impact of its products both during production and in subsequent use.

 

The new Civic continues that tradition and a particularly significant feature of the new model is that most of the plastic materials used within the interior are comprised of thermoplastic olefin (polypropylene) compounds which can easily be reprocessed into pellets and recycled.

 

Other key environmental aspects include the Civic's compliance with EU2000 and EU2005 emissions legislation and the returnless fuel supply system (see Engine section); and a wiring harness which is lead-free and uses compact routing to reduce cable runs.

 

 

Production and development

• Global coordination by New Model Centre
• Digital Manufacturing Circle development process
• Civic is first global model to be built using New Manufacturing System
• Q10 quality programme
• Advanced new manufacturing techniques for increased body accuracy

The new Civic in its various body styles is the first Honda to be launched simultaneously around the world. This was accomplished by combining the capabilities of Honda's autonomous business regions with global coordination through the New Model Center andNew Manufacturing System.

 

A major challenge in planning this global Civic launch was ensuring a consistent level of quality around the world.  To meet this challenge, Honda established the New Model Center in Tochigi, Japan.  From the earliest stages of development, manufacturing associates from Civic plants gathered at the New Model Center to provide critical input on the Civic development. 

 

Thousands of suggestions generated by the various plants on how to best build the new Civic to a higher quality standard were brought together into a single database at the New Model Center.  Civic engineers were able to access this information during the development process and associates tested the results while assembling prototypes.

 

Through this process, the design team was able to create a vehicle that can be produced on a global basis with high quality, efficiency and at a lower investment.  This is true at both the large, highly automated plants in Japan, the U.S. and Europe, and at smaller, less automated plants located in developing nations.

 

The new Civic is the first global model to be built using Honda's New Manufacturing System.  The system employs highly flexible welding robots and standardised assembly line layouts to reduce investment in new tooling, while shortening the time needed for new model development and manufacturing ramp up.  This flexible system will also allow Honda to adapt more quickly to changes in the marketplace with the production capability to add or change products in a short period of time, with minimal new investment.

 

Honda also applied a new development system called Digital Manufacturing Circle (DMC).  This uses state of the art Information Technology systems to increase the speed and efficiency of the new model development process.  The DMC system connects all the processes of Honda R&D, Honda Manufacturing and Honda suppliers by computer network, allowing them to share the same computer digitised drawings to develop new product designs through digital simulation.  As a result, Honda is able to develop new vehicles in a shorter time using fewer costly prototype models and parts.

 

A new level of quality

"Improving Quality 10 Times" is the goal behind a development and manufacturing campaign codenamed "Q10". This philosophy is reflected in every aspect of the 2001 Civic – from the initial+ designs through to the final manufacturing process.  Some of the areas where the Q10 initiative is most evident on the new Civic are in the area of increased body accuracy – making significant improvements in the fit and finish of panels and interior components.

 

Some of the manufacturing techniques that made these tighter tolerances possible included:

• Advanced programmable robots – this new equipment provides more precise welds, which translates into tighter tolerances. In addition, these robots can perform more functions, which 'shortens' the production line.
• Honda engineers created a special 'servo gun' that allows these robots to do more precise spot welds. This design is easier to control and moves faster than comparable hydraulic guns, which are used on other assembly lines. In addition, the electric servo guns require less energy to operate.
• With these new advanced welding robots, in most instances, the welding head remains stationary and the part is rotated. In the past – with the hydraulic systems – the part was stationary and the welding head moved, which is not as accurate.
• Accuracy was also improved by converting the existing manufacturing process to use a specialised jig for more precise, automated installation of the hinges and door panels. In the past, a skilled associate undertook door panel installation by hand.

The use of high-strength steel also creates added challenges in manufacturing, as it is considerably harder to form than typical sheet steel. This can prematurely wear dies (which can have a negative impact on quality and body clearances), and it is harder to weld and inspect. To overcome this challenge, Honda production engineers devised ways to create new durable dies and effectively check to ensure every vehicle is built to the same exacting tolerances.
