General Motors unveils Ultium Drive, a proprietary family of five modules and three motors for new electric vehicles

American automaker General Motors has unveiled a new family of Ultium Drive electric motors that will be used in all of the company’s new electric vehicles, including the new Bolt EV / EUV and GMC Hummer EV. Complemented with Ultium branded batteries, the family is a complete platform similar to the VW MEB.

The Ultium Drive family consists of five interchangeable drive units and three electric motors with different characteristics at their core. The ability to vary these components within one model will allow the company to choose the best option in terms of power, torque and energy efficiency of the propulsion system – any models (FWD, RWD, AWD) will be built on the basis of this “constructor”, from off-road pickup trucks to high-speed road models.

Note that Ultium Drive modules contain electric motors, a single-speed gearbox and control electronics, which simplifies the creation of electric vehicles based on them. The integration of the control electronics into the module has resulted in a 50% reduction in weight and a 25% reduction in module volume compared to the previous generation of GM motors.

The developers noted that the Ultium Drive platform will be more responsive than ICE counterparts and allow much more precise control of power and torque. They will be produced at the company’s factories around the world, which will allow actively developing the segment of electric vehicles for all key car markets.

Recall that on October 20, 2020, the GMC Hummer EV electric pickup and electric crossover will be presented. The long-awaited Chevrolet Bolt EV and Chevrolet Bolt EUV will hit the market in 2021, and the premium Cadillac Lyriq electric crossover, the Chevrolet electric pickup with a range of more than 650 km and other new products are expected in the coming years.
