On April 10, Hyundai Motor Group unveiled its advanced hybrid technology at the Next-Generation Hybrid System Tech Day held at Crest 72 in Seoul. Introducing a next-generation hybrid system that improves both performance and fuel efficiency with two built-in motors and various engine combinations, the automaker promised a perfect harmony of power and efficiency and an electrification experience beyond a hybrid.
A key feature of the new system is its parallel structure, which includes a P2 motor for driving and regenerative braking, and a P1 motor for starting, power generation, and driving assistance. This configuration achieves approximately 45% better fuel efficiency and about 19% higher peak power compared to previous models, while also ensuring smooth gear shifts and quiet operation.
The newly introduced 2.5-liter turbo hybrid engine incorporates an overexpansion cycle that optimizes the compression and expansion processes for enhanced efficiency.This engine delivers a maximum fuel economy of 14.1 km/l, a combined system output of 334 horsepower, and a peak torque of 46.9 kgf·m, positioning it as a top performer among large SUVs.
Hyundai has integrated several electrification-specific technologies into the hybrid system. These include an electronic all-wheel-drive system (e-AWD), enhanced vehicle stability technology (e-VMC 2.0), stay mode, Vehicle-to-Load (V2L), and smart regenerative braking. These features are designed to enhance driving performance and user convenience.
The stay mode allows users to operate climate control and multimedia systems without starting the engine, while the V2L feature can supply up to 3.6 kW of power to external devices, offering versatile applications.
Hyundai plans to implement this new transmission and engine technology across its vehicle lineup, from compact cars to large SUVs and luxury vehicles. Mass production is set to begin this month with the Palisade Hybrid, with a gradual rollout to other models.
Hyundai aims to launch a 2.5-liter turbo hybrid for rear-wheel drive applications in 2026 to further expand its premium hybrid lineup, including Genesis brand vehicles.
Vice President of Electric Vehicle Development, Han Dong-hee, stated that Hyundai is securing a diverse range of powertrain technologies to address the transition to electric vehicles and provide customers with a broader electrification experience.
