The 2022 GMC HUMMER EV Edition 1 is the first vehicle in production with GM’s all-new Ultium battery architecture and offers impressive on- and off-road features and a broad range of vehicle dynamics and performance features.
This new architecture provides the framework to integrate advanced technologies for optimal driving range and — in the case of the HUMMER EV — will enable performance and capabilities that would not be possible with a conventional vehicle architecture and propulsion system.
The 24-module Ultium battery pack and three-motor Ultium Drive system provide this all-electric supertruck best-in-class power output.
Edition 1’s three electric drive motors within Ultium Drive yields a combined GM-estimated 1,000 horsepower, and when multiplied through the front and rear drive unit gear ratios, there will be more than a GM-estimated 11,500 lb-ft of torque available at the wheels.
The single-motor front drive unit has a 13.3:1 fixed gear ratio and offers an electronic lockable differential, capable of delivering up to 100 percent of the motor torque to one wheel, in case traction is lost on the opposite wheel. All four wheels can be fully synchronized for true e4WD propulsion.
Two rear motors contained in one Ultium Drive unit will independently power the rear wheels through a fixed gear ratio of 10.5:1, with the capability of varying torque output to each wheel to optimize traction in off-road driving and highway-driving conditions.
Motor output can also be synchronized to simulate a locking differential.
