GM reveals the ‘Ultium’ motors that are key to its all-electric shift

For its part, GM said that its five Ultium Drive motors (packaged with single-speed transmissions) will make EVs lighter and more efficient. That’s because the power electronics are built into the drive assemblies, reducing their mass by half while increasing capability. That also makes it easier to scale the Ultium motors and batteries to high output vehicles like pickup trucks and performance EVs.

The company will develop the motors alongside its next-gen EVs in order to keep everything in-house. Future vehicles using the tech could include Cadillac’s’ freshly announced Lyriq luxury SUV, the Hummer EV coming next month, the next-gen Bolt EV (delayed until next year) and the crossover Bolt EUV coming in summer 2021.
