HONDA’S HR-V e:HEV OUTPERFORMS RIVAL POWERTRAINS IN REAL-WORLD TESTING

HONDA’S HR-V e:HEV OUTPERFORMS RIVAL POWERTRAINS IN REAL-WORLD TESTING
  • Honda’s e:HEV proven to be more efficient than both competitor mild and plug-in hybrid systems over a prescribed route
  • e:HEV is the most practical everyday solution for most driver needs, with no need to plug in, no range anxiety and ultra-low emission driving
  • Honda’s new HR-V, CR-V, Jazz, and forthcoming all-new Civic are offered exclusively as ‘self-charging’ full hybrids

 Honda’s well-established e:HEV hybrid system has proven to be more efficient and usable than other hybrid powertrains, according to the company’s latest internal, real-world testing*. The e:HEV system, which has formed the basis of Honda’s Electric Vision is found on board the brand’s HR-V, CR-V, Jazz, and forthcoming all-new Civic models as standard. Built around a highly efficient Atkinson-cycle petrol engine and dual electric motors, the e:HEV system outperformed both mild- and plug-in-hybrid systems used in competitor models.

Test data showed that over a prescribed 116km route, which took in a variety of traffic densities and road types, the e:HEV powertrain offered the best elements of other hybrid system types, but with higher levels of real-world efficiency. With no need to plug-in and charge, the HR-V is suitable for every driving situation, combining the responsive performance of an electric vehicle with the usability of conventionally powered cars, without the range anxiety associated with monitoring battery charge levels.

In evaluating the powertrain of the all-new HR-V and its in-class rivals on public roads, the e:HEV system significantly outperformed a competitor vehicle fitted with 48V ‘mild’ hybrid system; something increasingly found in many new vehicles today. A mild hybrid uses a 48V battery and an integrated starter generator that allows the engine to switch off when coasting or braking.

Under test conditions, the all-new HR-V carried a weight disadvantage over its mild hybrid rival of around 120kg due to the inclusion of a full hybrid system. Despite the marginal increase in weight, the advanced powertrain of the HR-V ensured that it delivered an average consumption of 1.1L/100km (10mpg) better than its rival. In urban environments, this margin extended out to 4.5L/100km (128.15mpg) better than the 48V powered competitor, underlining the true flexibility of the e:HEV system.

What sets the e:HEV system apart is how its three drive modes interchange seamlessly to ensure optimum performance in all driving scenarios – something that mild hybrid systems cannot do. The intelligent Electronic Control Unit constantly and automatically cycles between Electric Drive, Hybrid Drive and Engine Drive, depending on which is the most fuel-efficient drive mode in the specific driving situation.

During testing, the e:HEV system was found also to deliver efficiency comparable with a rival manufacturer’s PHEV. While owners of plug-in hybrids are required to keep their vehicle’s battery topped up to achieve maximum efficiency, Honda’s self-charging e:HEV system operates at its most efficient level at all times, without any charging from a wall socket required. Despite utilizing the rival’s latest iteration of PHEV powertrain*, the plug-in competitor delivered similar total elapsed time in EV drive mode in urban environments to the HR-V showing no real benefit to the more complex plug-in system. In extra-urban environments, where the majority of vehicles operate, the HR-V surpassed the PHEV for total time spent in EV mode by 3%.

The e:HEV system provides users with a seamless driving experience. The ultra-smooth transitions between drive modes ensure an uninterrupted, smooth and relaxing drive also capable of providing powerful acceleration and, as proven, exceptional real-world efficiency.

Honda’s expertise with hybrid systems is long-standing; the original Insight from 1999 established Honda as a world leader in hybrid technology. Since then, Honda has continued to develop its hybrid technology, with its advanced two-motor e:HEV system now used in the Jazz, CR-V, all-new HR-V and upcoming 11th-generation Civic.

*Disclaimer: Please note, the PHEV competitor vehicle was tested in ‘Charge Sustain’ (CS) mode with a partially discharged battery state of charge. All real-world testing conducted during this process was conducted by Honda Motor Europe. Figures achieved during this test may vary depending on individual driving style and may impact EV drive mode range and overall efficiency.
