GM’s Multi-Brand, Multi-Segment EV Strategy

The heart of GM’s strategy is a modular propulsion system and a highly flexible, third-generation global EV platform powered by proprietary Ultium batteries.

In North America, GM EVs will be powered by rectangular, pouch-style battery packs that are simple, lightweight and space-efficient.

GM’s ability to stack batteries vertically is unique in the industry and it allows for a flat cabin floor and more interior room than comparable EVs that use cylindrical battery packs.

​The pack also allows engineers to deliver vehicles with an optimized weight distribution and a lower center of gravity to improve ride and handling.

GM’s new Ultium batteries will have the highest nickel and lowest cobalt content in a large format pouch cell.
Large format pouch cells require less wiring and plumbing than small cylindrical cells.

GM’s battery management system is built in, which eliminates 80 percent of the battery pack’s wiring compared to the Bolt EV.

Ultium energy options range from 50 to 200 kWh, which could enable a GM-estimated range up to 400 miles or more on a full charge with 0 to 60 mph acceleration as low as 3 seconds. Motors designed in-house will support front-wheel drive, rear-wheel drive, all-wheel drive and performance all-wheel drive applications.

Ultium-powered EVs are designed for Level 2 and DC fast charging. Most will have 400-volt battery packs and up to 200 kW fast-charging capability while GM’s truck platform will have 800-volt battery packs and 350 kW fast-charging capability.
