When Honda pulled the wraps off the Prelude at the Japan Mobility Show, there was an assumption that it’ll simply be a sportier version of the current Civic Hybrid given that the show car had the compact sedan’s interior. That, however, won’t be the case as Honda confirms that the sixth-generation coupe will debut the brand’s next-generation e:HEV hybrid system and S+ Shift system.
The next-generation e:HEV strong hybrid system will be composed of new combustion engines, drive units, and cooling systems all equating to a 10 percent improvement in fuel efficiency compared to the first-generation 2-motor hybrid system.
At the heart of the system is an all-new 1.5- or 2.0-liter engine that will offer improved efficiency across a wider RPM range. Targeting the ideal mix ratio of oxygen to fuel, the 1.5-liter unit, for example, is targeted to have a 40 percent efficiency improvement over the current 1.5-liter engine. This quest for efficiency, according to Honda, will not compromise power output for all driving situations.
Unique to the Honda e:HEV system and something that’ll carry onto the next-generation system, the engine can still directly power the drive wheels via a lock-up clutch. However, in modes which will require electric drive or assist, the next-generation e:HEV system will have a front unit that’s smaller, but with increased efficiency and power.
Mated to this next-generation engine is a more efficient transmission system. It will offer more scenarios where the electric drive or assist is used. For example, the new transmission will still enable electric assist to be used during high-speed highway driving. The upcoming e:HEV system will also feature the Honda S+ Shift. Coming as standard on all models equipped with the new e:HEV system, starting with the Prelude, the Honda S+ Shift can precisely control the engine RPMs during acceleration and deceleration to realize more direct and sharper responses.
Not confirmed for the Prelude, but announced by Honda altogether, is a new electric all-wheel drive (E-AWD) unit. This tech, which will be used by both their hybrid and battery electric vehicles, will offer the precise distribution of power between the front and rear axles compared to the current mechanical all-wheel drive set-up.
Finally, everything comes together with a brand-new platform. Starting with a new mid-sized platform, Honda says it will offer reduced weight—up to 90 kilograms in some cases—with improved rigidity and stiffness. Honda will offer a new “steering stability index, which provides the ability to flex the vehicle body to control load on each tire during cornering.” And because the entire thing is modular, there will be increased commonality among future models—up to 60 percent—with things like the engine room and rear floor shared across model lines.
The Honda Prelude will be the first model to enjoy these new technologies when it debuts in showrooms around the world starting in early 2026. So far, markets confirmed to receive the Prelude include North America, Japan, and Europe. No word for markets such as Southeast Asia. It’s likely that the production Prelude will make its debut at the Japan Mobility Show which is happening late 2024.
