Hyundai develops new petrol-electric hybrid systems
Words NZ Autocar | Images Hyundai
Hyundai has unveiled a next-generation hybrid powertrain system it says delivers a new standard for power and efficiency.
The transmission-integrated system the firm says will improve the driving and ownership experience for its customers.
The new transmission features two integrated motors that can be paired flexibly with a range of internal combustion engines. Hyundai says this offers optimised performance and fuel efficiency.
The powertrain will go into a range for vehicles, and is due soon in Palisade with a redeveloped 2.5L turbopetrol at its core. All of the hybrid transmissions include a new P1 motor that handles starting, battery energy generation and energy deployment to assist propulsion. A P2 driving motor is responsible for propulsion and regenerative braking.
Designers state that the dual-motor set-up improves power, performance and fuel efficiency. It also achieves smooth shifting and reduced NVH for a more refined driving experience.
Power outputs for the new hybrid system range from a low- of 73kW to a high of 220kW.
Convenience features such as Stay Mode, Vehicle-to-Load (V2L) functionality, and Smart Regenerative Braking are borrowed from the company’s BEV programme. Bigger models will use the 2.5 turbopetrol as ICE power. However, a 1.6-litre turbo hybrid powertrain will also be available at some point.
Evidently enhanced cylinder flow and a high-efficiency cycle optimised for hybrids mean much improved fuel efficiency.
Engine start time is much quicker with the P1 acting as a starter motor. And precise control means the engine operates primarily in its high-efficiency range.
In the new Palisade hybrid, for example, maximum fuel efficiency is a claimed 7.1L/100km. System output is 245kW and 460Nm. Hyundai claims 45 per cent improved fuel efficiency, 19 per cent more power, and a nine percent improvement in maximum torque from its hybrid system compared with a 2.5 turbopetrol model.
The company is also planning to integrate other electrification technologies to enhance performance, efficiency and competitiveness in its new hybrid vehicles.
