General Motors announced that it will design, develop and manufacture a family of five interchangeable electric drive units and three motors, known collectively as “Ultium Drive.” GM said that Ultium Drive and its modular architecture will help it transition to a fully electric lineup, and provide significant advantages over GM’s previous EVs in performance, scale, speed to market and manufacturing efficiencies. Ultium Drive family. General Motors’ next-generation EVs are expected to be powered by a family of five interchangeable drive units and three motors, known collectively as “Ultium Drive.” Ultium Drive combines electric motors and single-speed transmissions to apply power—generated by Ultium battery cells ( earlier post )—to the wheels of GM’s upcoming electric vehicles. Ultium Drive will be more responsive than its internal combustion equivalents with precision torque control of its motors for smooth performance. GM expects these motors within Ultium Drive to offer industry-leading torque and power […]
