Hyundai Motor Group unveiled its next-generation hybrid system during its Next-Gen Hybrid System Tech Day. This new powertrain features a dual-motor setup integrated into a newly developed transmission.
According to Hyundai, the powertrain can be paired with a range of combustion engines, optimising both performance and fuel efficiency. For starters, the P1 motor handles engine starting, battery energy generation, and energy deployment to assist propulsion.
On the other hand, the P2 motor is responsible for driving the wheels and regenerative braking. The transmission also incorporates Active Shift Control and the P1 motor to accelerate gear changes and reduce vibrations when the engine engages.
This configuration is suitable for vehicles ranging from small cars to large SUVs and can be matched with engines producing anywhere from the low 100 PS range up to mid-300 PS. The first engine to be paired with this powertrain is the newly developed 2.5-litre turbo hybrid unit.
This engine utilises a smart over-expansion cycle that optimises the air-fuel mix within the cylinder for improved fuel economy and cleaner performance. Furthermore, to enhance engine efficiency, Hyundai has refined the piston design and introduced a significantly broader triple fuel injection range.
This powerplant is currently featured in the all-new Palisade hybrid, offering a fuel consumption rate of 14.1 km/litre and producing 334 PS and 460 Nm of torque. Additionally, a new 1.6-litre turbo hybrid is being introduced, which is both quick and economical thanks to increased torque and approximately 4% improved fuel efficiency.
Hyundai is also bridging the gap between hybrid vehicles and EVs with advanced electrification technologies such as e-AWD, Stay Mode, V2L, and Smart Regenerative Braking. Features like e-Handling 2.0 and e-EHA 2.0 improve cornering stability while e-AWD uses a P4 motor on the rear axle to boost traction and acceleration.
Meanwhile, e-Ride 2.0 enhances ride comfort by using motor control to minimise pitch and bounce when driving over speed bumps. In addition, Stay Mode allows the car to power in-cabin amenities such as media and air conditioning for up to an hour without starting the engine. A reservation feature utilises the navigation system to prepare the battery before arrival.
Regardless of whether the engine is running, the V2L (Vehicle-to-Load) system can deliver up to 3.6 kW to power external devices. Smart Regenerative Braking and Hierarchical Predictive Control use navigation data to maximise energy recovery and fuel efficiency.
With production already underway for the new Palisade hybrid, Hyundai plans to roll out the new system across more Hyundai and Kia vehicles, including a rear-wheel-drive variant in 2026. It has also been confirmed that Hyundai’s premium brand, Genesis, will adopt this technology in upcoming luxury hybrid models.
