Honda is advancing the evolution of its electrified mobility solutions with the next-generation e:HEV system, designed to deliver a more refined and engaging driving experience while achieving new levels of environmental performance. This development reflects Honda’s commitment to continuously enhance motor and engine efficiency, reinforcing its role in the future of electrification.
The Next-Generation e:HEV Refined by Sensory-Rich Technologies
The e:HEV system—Honda’s proprietary two-motor hybrid configuration—continues to serve as a core technology in the brand’s electrification strategy. It balances environmental performance with a dynamic driving feel. With its latest evolution, Honda aims to heighten the connection between the vehicle and driver through improved responsiveness, electric all-wheel drive (AWD), and component upgrades including the engine, drive unit, and control technologies for small- and medium-sized models.
Introducing a Purpose-Built Electric AWD System
Driving enjoyment is rooted in stability, precise handling, and confidence under all conditions. For next-generation e:HEV vehicles, Honda is introducing an electric AWD system featuring a newly developed rear drive unit powered by an electric motor. This setup works in tandem with the front drive unit, enhancing initial acceleration and enabling more precise distribution of driving force based on road conditions. The result is stronger traction, especially when starting on low-grip surfaces or negotiating turns.
The rear motor unit features a 50-kilowatt-class output suitable for integration in vehicles up to medium size. By utilizing the instantaneous response and fine control capabilities of electric motors, the system delivers the sophisticated driving feel expected from modern hybrid powertrains.
Improved Packaging Efficiency and Comfort
Unlike mechanical AWD systems that require a propeller shaft running through the cabin floor, Honda’s electric AWD allows for a flatter floor structure by eliminating the center tunnel. This redesign improves rear seat comfort and makes it possible to relocate the battery pack under the seat, freeing up additional cargo space.
Advanced AWD Control Through Motor Technology
Building on its experience with mechanical AWD systems, Honda applies precise and flexible front-rear torque distribution using electric motor characteristics. The system adjusts force based on vehicle posture and tire contact loads, optimizing grip and stability during acceleration, deceleration, and cornering. Rear regenerative braking is also utilized to stabilize vehicle posture during braking, while torque distribution during cornering helps reduce understeer and improves steering response.
Independent Slip Control with Newly Developed TCS
A new Traction Control System (TCS) was also developed to complement the electric AWD system. Unlike conventional systems that rely on a central control unit, Honda’s new TCS uses independent ECUs for the front and rear motors. These detect and respond to wheel slippage with high speed and precision, allowing the system to apply or reduce power only where necessary. This results in maximum tire grip even on low-traction surfaces such as snowy or inclined roads, offering more consistent and reassuring performance than traditional mechanical AWD setups.
Maximizing Traction Across Varied Driving Scenarios
By integrating the electric AWD and the new TCS, Honda offers drivers greater control and confidence. Whether navigating winding roads or icy surfaces, the system supports a stable vehicle posture through precise braking and torque distribution. The seamless transition of torque from front to rear ensures optimal handling through corners and helps preserve grip during acceleration, resulting in a more engaging and secure drive.
