Hyundai Unveils Dual-Motor Hybrid System with 45% Efficiency Gain

Seoul, South Korea—Hyundai Motor Group introduced a new hybrid powertrain system on Monday that uses dual integrated motors.

The company says this system delivers 45% better fuel efficiency compared to its traditional combustion engines.

The South Korean automaker said the system features a transmission with two motors that can work with various internal combustion engines across different vehicle segments.

According to company data presented at its technical event, the first application in the Palisade model with a 2.5-liter turbocharged hybrid engine produces 334 horsepower and 460 Newton meters of torque, with fuel efficiency measured at 14.1 kilometers per liter.

"This system integrates our engine, transmission, and hybrid development experience with electrification technology," Dong Hee Han, Executive Vice President at Hyundai Motor Group, said.

The company stated that the transmission incorporates a P1 motor for starting and energy generation, while a P2 motor handles propulsion and regenerative braking.

Hyundai also announced a 1.6-liter turbocharged hybrid variant that the company says improves fuel efficiency by more than 4% in mid-size SUVs compared to previous models.

Maximum torque increases from 367 Nm to 380 Nm.

According to technical details released by Hyundai, the system employs what the company calls an "over-expansion cycle" that modifies valve timing during compression to improve engine efficiency.

The automaker said the system includes additional features from its electric vehicle development, such as Electric All-Wheel Drive with a rear-axle motor and Vehicle Motion Control systems.

Other capabilities include Vehicle-to-Load functionality with a maximum output of 3.6 kW for external devices and Stay Mode, which the company says allows the use of vehicle amenities for up to one hour without engine operation when the battery charge is between 70% and 80%.

Hyundai said it plans to implement the new system across its vehicle lineup, with a rear-wheel-drive variant scheduled for 2026 and later expansion to its Genesis luxury brand.

The company indicated that launch timing would vary by model, region, and market.
