Hummer is returning on the market after a 10 year absence. This time though, Hummer has a new recipe for its fans and clients. Enabled by a GM-designed three-motor e4WD system and advanced, selectable driving modes, the 2022 GMC HUMMER EV will be the ultimate off-road EV supertruck, with all-new features developed to help conquer tough obstacles and terrain.
The e4WD drive system with torque vectoring will enable maneuverability and traction unlike anything GM has ever offered and should allow the vehicle to reach new destinations over the most challenging terrain — with capabilities including climbing 60-percent grades (forward and reverse), scaling 18-inch verticals and fording water more than 2 feet deep.
HUMMER EV’s Drive Mode Control’s five drive modes — four pre-configured modes and the driver-configurable My Mode — will enable the driver to tailor the vehicle’s performance, including torque distribution, four-wheel steering, ride height, shock damping, throttle maps, brakes and interior sound enhancement. The modes suit a variety of driving conditions, from rock crawling to highway driving and even trailering.
Drive Mode Control also includes Terrain Mode, which offers unique one-pedal EV driving tailored for off-roading. It allows the driver to negotiate challenging terrain at low speeds by simply modulating input on the accelerator pedal.
The system can channel more power to a single wheel, keeping the HUMMER EV moving in some of the toughest driving conditions and terrain, all with unprecedented maneuverability and suspension articulation — including nearly 13 inches of suspension travel.
The HUMMER EV also improves upon GM’s acclaimed Continuous Damping Control, a real-damping system that “reads” the road every 2 milliseconds to enable continual damping adjustments in order to optimize comfort on and off the road. It is tailored for the unique capabilities and range of motion in the HUMMER EV, incorporating new damping adjustments based on suspension travel, which enhances refinement ride comfort when off-roading.
Terrain Mode will offer two braking calibrations, with a mild braking option for two-foot driving and a purpose-designed one pedal driving control in low-speed off-road driving. As pioneered by GM for other electric vehicles, one pedal driving enables the driver to accelerate and decelerate using onl y the accelerator pedal. With Terrain Mode, that same one pedal control is adapted with unique calibrations for speed-limited off-road driving, allowing the driver to negotiate steep grades, rock crawling and other challenging terrain without having to toggle between the accelerator and brake pedal.
The HUMMER EV will be the first full-electric vehicle in GMC’s portfolio and is powered by General Motors’ new Ultium battery system. The battery cells will be produced as part of a joint venture with LG Chem, at a new facility, in Lordstown, Ohio.
