Honda develops new generation hybrid engines

Due to a slowdown in global demand for electric vehicles (EVs), Honda has decided to refocus its efforts on the production of hybrid engines.

Recently, Honda has reportedly been developing several new generation e:HEV technologies for use in upcoming electric hybrid vehicles.

1. New 1.5L & 2.0L Engines

Both the new 1.5-liter and 2.0-liter Atkinson cycle engines will be paired with a front-wheel drive unit and integrated cooling system in a more compact package.

Honda aims for the new engine’s fuel consumption to be 10 percent more efficient when combined with a new generation midsize platform currently under development.

By extending the RPM range where the engine operates most efficiently, the new 1.5-liter engine can achieve fuel savings that are 40 percent better compared to the existing 1.5L engine.

Both engines will share the same hybrid components to reduce manufacturing costs.

2. New Mid-size Platform

In addition to the e:HEV system, Honda will also be refreshing its midsize platform for their electric hybrid vehicles.

This modular platform promises high chassis stability, sporty driving dynamics, and an overall weight that is 10 percent lighter compared to existing e:HEV models.

Additionally, Honda aims to develop the lightest platform in its class, reducing weight by 90 kg compared to the existing platform through a new design approach.

Achieving over 60 percent commonality across all midsize models will contribute to more efficient and cost-effective production of various models.

3. Honda S+ Shift

Honda S+ Shift is a new function introduced to enhance the driving pleasure and amplifies the sense of oneness between the driver and the vehicle.

According to Honda, S+ Shift precisely controls engine RPM during acceleration and deceleration to realize direct driving response and accurate gear shifting.

The resulting engine sound will be synchronized with the Active Sound Control (ASC) system, where the sound quality will be enhanced through speakers to further enrich the exciting driving experience.

4. Electric AWD System

Starting with the new generation e:HEV models, Honda will employ an electric all-wheel drive (AWD) system (E-AWD).

Compared to mechanical AWD systems, E-AWD can increase maximum traction and contribute to more powerful initial acceleration performance.

The E-AWD system can also optimize the distribution of front-to-rear driving energy based on tire-ground contact during acceleration, deceleration, and cornering.

Interestingly, the e-AWD system can also be shared with any EV.

With this new technology, Honda is determined to reduce production costs for each electric hybrid model by up to 50 percent for the 2027 model year, compared to similar models launched in 2018.
