Honda’s next-generation hybrid system will debut

With the launch of Honda’s next-generation e:HEV hybrid system, overall fuel efficiency will increase by 10%

Iconic Japanese automaker Honda revealed its next-generation e:HEV hybrid system at a press conference in Tokyo, Japan today (December 18, 2024). These next-generation technologies are planned to be installed in future hybrid electric vehicles. Additionally, the company has made some updates to its original 2-motor e:HEV hybrid system.

Honda’s next generation hybrid system

Honda, with its mission to continuously evolve and adapt to changing technologies, showcased its next-generation e:HEV hybrid system. These powertrains work on the same principles as Honda’s original 2-motor e:HEV hybrid system, but will receive meaningful updates to deliver on the promise of a 10% improvement in fuel efficiency.

The next generation e:HEV system will be available in small (1.5L engine) and medium (2.0L engine) system sizes. Honda’s next-generation e:HEV system will offer three efficient operating modes. The system switches seamlessly between these three modes. First, we have an electric drive mode that employs all-electric driving for a defined driving range.

Secondly, we have cars with hybrid drive modes that run primarily on the electric motor, with the engine acting as a generator to charge the battery. Finally, we have engine drive mode, where the clutch is engaged and the engine is now connected directly to the wheels. The last mode is unique to Honda’s e:HEV hybrid system.

Honda’s next-generation e:HEV hybrid system will improve the efficiency of the 1.5L and 2.0L engines. Power conversion and engine efficiency in hybrid mode are said to have been improved for maximum combustion efficiency. Engine and electric motor performance is also said to improve with increased torque transmission efficiency.

Honda Prelude debuts next-generation e:HEV hybrid system

For the sake of business viability, Honda aims to simplify many components between the 1.5L e:HEV system and the 2.0L e:HEV system. Reducing package size and increasing efficiency will also play a key role in reducing production costs. The next-generation e:HEV hybrid system will debut in 2025 with the Honda Prelude.

Key improvements include the new Honda S+ Shift bringing “driving pleasure”. Honda S+ Shift will precisely control engine speed during acceleration, deceleration and gear changes. Honda’s next-generation e:HEV will use electric all-wheel drive (E-AWD) technology shared with hybrids and electric vehicles to enable better driving dynamics and improve performance in situations where traction is reduced.

In addition to the powertrain, Honda will also overhaul its next-generation e:HEV. Steering stability index, vehicle weight reduction of 10%, platform weight reduction of 90 kg, multiple body sizes brought by modular architecture and cost reduction and other factors.
