General Motors has spent a lot of time lately on the possibilities of its upcoming Ultium battery technology, but has said significantly less about the cars that will drive the cells. That changed on Tuesday when the company unveiled its new Ultium Drive cars. With today’s announcement, the range consists of three different models: a 180 kW front-wheel drive model, a 255 kW rear and front-wheel drive variant and a 62 kW four-wheel drive auxiliary engine. The first two models are permanent magnet motors GM designed to try to reduce the dependence on heavy rare metals.
The company did not talk about the specific torque and power density characteristics of each car, but claims that they should deliver ‘excellent’ performance on those fronts. It also revealed that the 2022 Hummer EV will feature three of the 255 kW models. GM claims that they will enable the vehicle to deliver a combined torque of 11,500 ft / lb and accelerate from zero to 60 miles per hour in about three seconds.
GM says its engineers designed the cars with scalability in mind. Each can be made using similar tools and manufacturing techniques. It also found a way to integrate components such as the inverter directly into the motors, a performance that, according to the company, should reduce costs and simplify manufacturing.
