GM reveals three new Ultium motors for future EVs

General Motors Co. President Mark Reuss revealed three new motors for the automaker’s Ultium-based electric vehicles Tuesday at the 2021 Mackinac Policy Conference.

The motors — a 180-kilowatt front-drive motor, a 255-kW rear and front-drive motor, and a 62-kW all-wheel-drive assist motor — are designed in-house by GM and “built as a scalable family, sharing design principles as well as similar tooling and manufacturing strategies,” GM said…

GM used artificial intelligence and machine learning to determine the most efficient ways to distribute torque in three-motor systems. And the software on GM’s EV motors can be reused in other applications from a complete lineup of vehicles to power electronics components like the power inverter module.
