The new Hyundai hybrid system consists of a newly-developed transmission with two integrated motors, which can be coupled with multiple ICEs (internal combustion engines) motors. This setup will not only optimize fuel efficiency and performance of the vehicles across segments, but it’s also compatible with several electrification-focused technologies aimed at improving ride comfort, refinement and driving performance.
New Transmission:
Hyundai’s next-generation hybrid powertrain features a newly-developed transmission with a new P1 motor, which handles starting, energy generation and its deployment to assist propulsion. The P2 driving motor helps aids in propulsion and regenerative braking.
This dual-motor setup is claimed to enhance power, performance and fuel efficiency, while reducing noise and vibrations and achieving smooth shifting. The new transmission will be compatible to Hyundai’s multiple ICE engines, offering power ranging from below 100PS to the mid-300PS.
New Hyundai Hybrid System Explained:
The new hybrid system from Hyundai supports features such as Vehicle-to-Load (V2L) functionality, Stay Mode and Smart Regenerative Braking. The 2.5L turbo petrol hybrid engine will be the first powertrain to use the next-generation hybrid system, followed by a new, next-generation 1.6L turbo petrol hybrid powertrain.
The 2.5L engine with the new hybrid system and new P1 motor reduces power losses, while enhancing cylinder flow within the engine. The adaptation of a high-efficiency cycle optimized for hybrids will further improve fuel efficiency.
The 2.5L turbo hybrid system uses an ‘over-expansion cycle’, which delays intake valve closure during compression to lower the effective compression ratio of the mixed gas in the cylinder, while maintaining a high expansion ratio during the combustion process. This results in less power consumption during mixture compression while maximizing energy generated after combustion, significantly enhancing engine efficiency.
Furthermore, Hyundai has improved piston design and significantly expanded triple fuel injection range, which enhances combustion speed, stabilizes combustion and suppresses detonation 0 further improving engine efficiency.
