Stellantis has unveiled a new 1.6-liter turbocharged hybrid powertrain that delivers 210 horsepower and 230 lb.-ft. of torque while achieving an estimated 37 miles per gallon combined in city and highway driving.
The system integrates a turbocharged engine with a two-motor transmission, providing hybrid performance without the need for plug-in charging.
The powertrain uses a 1.03-kWh lithium-ion battery to support short-distance electric-only driving at speeds up to 62 mph. Its transmission incorporates two motor-generators and a planetary gearset to provide dual electrical and mechanical power flows, enabling EV, hybrid, and regenerative braking modes.
Stellantis designed the engine with a high-pressure direct injection system, Miller Cycle combustion, and a liquid charge air cooler for improved efficiency. Electrically driven pumps reduce engine load, and regenerative braking captures kinetic energy to recharge the battery.
A Dual Motor Power Inverter maintains the 12-volt vehicle supply and boosts high-voltage output for additional torque when needed.
The powertrain includes all-wheel drive capability and automatic torque distribution systems for performance and efficiency across various driving conditions.
Engine assembly takes place at Stellantis’ Dundee Engine Plant in Michigan, and the system meets SULEV 30 emissions standards. Stellantis emphasized that the technology balances efficiency, performance, and versatility, supporting the company’s broader hybrid and electrification strategy.
