The Hyundai group presents its new generation hybrid system.
> Hyundai Motor Group's advanced next-generation hybrid system incorporates innovative electrification technologies to improve performance and fuel efficiency.
> The new transmission features two integrated engines and will be combined with multiple engines in a wide range of vehicles.
> The optimized design allows for seamless integration of the new P1 engine, increasing energy transfer efficiency for starting, battery power generation and driving performance.
> The 2.5-litre turbocharged petrol engine achieves up to a 2.9% increase in efficiency, with improvements including an optimised thermodynamic cycle and fuel injection strategies.
> The new state-of-the-art hybrid system offers 45% more fuel efficiency and 19% more power compared to ICE powertrains in the same class, providing enhanced refinement.
> It employs sophisticated electrification technologies and advanced motor and battery control to increase drivability and deliver a leading hybrid driving experience.
> The new next-generation 1.6 hybrid engine will also be available, offering customers a greater choice of options.
> The upgraded hybrid powertrains offer a power output range from the low region of 100 hp to mid-300 hp, initially debuting in the Hyundai Palisade 2.5 turbo hybrid
Focusing on the P1+P2 parallel structure and combustion engine improvements, fuel efficiency and power performance have been improved while smoother shifts and better powertrain refinement have been achieved.
By connecting the P1 engine directly to the engine, the system reduces starting time. The precise control of the load and driving force of the P1 and P2 engines ensures that the engine operates within a high-efficiency range, thus improving fuel consumption.
The 2.5-litre petrol turbo hybrid system used in the new Palisade offers maximum fuel efficiency of 14.1 km/l, maximum system output of 334 hp and maximum torque of 460 Nm, delivering approximately 45 per cent better fuel efficiency, 19 per cent more peak power and a nine per cent improvement in peak torque compared to a turbocharged petrol model of 2.5 liters. 1
The next-generation 1.6-liter gasoline turbo hybrid improves fuel efficiency by more than four percent in a midsize SUV compared to previous models, increasing the system's maximum torque rating from 367 Nm to 380 Nm and improving throttle response.
In addition, by incorporating the P1 engine into the hybrid transmission logic with Active Shift Control (ASC), the system achieves faster and smoother gear changes than before. Improved engine clutch control further reduces engine engagement time when switching from EV mode, improving comfort and performance. The P1 engine is also used to reduce vibration and thud of the engine during idling battery charging, thus enhancing interior refinement.
Hybrid lineup to expand from compact to large and luxury models:
The Group plans to combine the new hybrid transmission with various engines across a system output from the low-100 PS range to the mid-300 PS region, introducing a diverse lineup of hybrid vehicles from compact to large and luxury classes.
With this expanded system output coverage, the hybrid powertrain lineup will increase from three models to five, with the latest 2.5 turbo hybrid powertrain making its debut in the all-new PALISADE hybrid, which began mass production this month. This system will be applied to other Hyundai and Kia models in the future.
The Group plans to introduce a rear-wheel-drive 2.5 turbo hybrid system in 2026 and aims to gradually expand its hybrid technology to the Genesis luxury brand by applying this powertrain to key models over time.
For all future hybrid models, the Group plans to apply the newly unveiled hybrid system and further electrification-focused technologies, tailoring these to the characteristics of individual vehicles and classes, as well as regional market requirements.
