It will be equipped with three 255 kW motors
The Hummer EV should produce 11,500 lb-ft of torque
Horsepower ratings haven’t been announced yet, but 0 to 60 mph (96 km/h) should only take 3 seconds
The 2022 GMC Hummer EV has received a lot of attention since General Motors started teasing it in early 2020, but few technical details were know until today, when the company released information on its new Ultium family of electric drive motors.
This new range of electric motors will consist of a 180 kW front-Wheel Drive unit, a 255 kW Rear or Front-Wheel Drive unit and a 62 kW assist motor designed for All-Wheel Drive vehicles.
These motors are a big step forward for the company since most of their control circuits are integrated into the casing, rather than being installed somewhere else in the vehicle, and the same goes for the inverters.
This innovation should allow for a lower production cost as well as a reduction of weight associated with drive electronics of almost 50%, while capabilities should increase by 25% when compared to the company’s previous generation electric powertrains, according to General Motors.
The automaker also revealed that the GMC Hummer EV will use three of the 255 kW motors, which should enable the truck to produce the 11,500 lb-ft of torque the company has been promising.
Power figures have not been officially revealed, but GM says to expect around 1,000 horsepower and a 0 to 60 mph (96 km/h) acceleration run of around 3 seconds, the same time announced for the Rivian R1T which will be the Hummer pickup’s prime competitor.
More details are expected ahead of the truck’s first deliveries in the fall of 2022.
