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.
They are a 180-kilowatt front-drive motor, a 255-kW rear and front-drive motor, and a 62-kW all-wheel-drive assist motor.
“Twenty years of electric drive system development and more than 100 years of high-volume vehicle engineering are helping GM pivot quickly from conventional vehicles to EVs,” Reuss said at the conference sponsored by the Detroit Regional Chamber. “Our vertical integration in this space, encompassing both hardware and software, helps give us control over our own destiny and a significant competitive advantage.”
The motors can be used on a “wide spectrum of vehicle types, from performance cars to work trucks,” GM said.
GM engineers also have developed software for Ultium Drive’s motor controllers, which GM says is key to delivering “the propulsion needs of various vehicle types with a minimal set of components.”
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.
GM’s all-new EV motors and integrated power electronics, within Ultium Drive units, will debut on the 2022 GMC Hummer EV later this year.
The announcement came the same day as Motor Bella, the Detroit Auto Dealers Association auto event happening at M1 Concourse in Pontiac, where GM is displaying its Hummer EV SUV.
