2022 GMC HUMMER EV Off-Road Supertruck Revealed
GMC has revealed the 2022 HUMMER EV, an off-road supertruck propelled by a GM-designed three-motor e4WD system with selectable driving modes and advanced features developed to help conquer tough obstacles and terrain. The unique 4WD drive system with torque vectoring will enable maneuverability and traction unlike anything GM has ever offered — with capabilities including climbing 60-percent grades in both forward and reverse, scaling 18-inch verticals and fording water more than 2 feet deep. Heavy-duty ball-spline halfshafts maximize axle articulation for maneuverability. A driver-selectable front e-Locker differential is coupled with a rear virtual locker for the dual-motor rear drive unit. Skid plates protect all critical underbody components including the battery pack and drive units. Front and Rear underbody cameras have live "virtual spotter" guides to help drivers navigate obstacles and place wheels on and off the trail. An Extreme Off-Road Package will include selectable four-wheel steering with CrabWalk, a segment-exclusive feature that turns the rear wheels at the same angle as the front wheels (up to 10 degrees) at low speeds, allowing diagonal movement of the vehicle, for an even greater range of maneuverability in tight off-road conditions. Adaptive Air Suspension will enable the suspension height to be controlled by the driver or via automatic settings to suit a variety of situations.
The 24-module Ultium battery pack and three-motor Ultium Drive system will provide this all-electric supertruck best-in-class power output. GM estimates a combined 1,000 horsepower, and when multiplied through the front and rear drive unit gear ratios, GM estimates there will be more than 11,500 lb-ft of torque available at the wheels... a staggering number to be sure, just don't ask us how that math works. The pack’s low mounting position in the chassis contributes to a low center of gravity, enhancing the vehicle’s overall feeling of control and stability. The compact construction of the Ultium battery pack also contributes to HUMMER EV’s ideal off-road proportions, including a short front overhang and short front breakover angle.With GM’s state-of-the-art nickel, cobalt, manganese, aluminum (NCMA) chemistry, HUMMER EV’s Ultium batteries will have some of the highest nickel and lowest cobalt — a rare and costly material — content of any large-format pouch cell. The breakthroughs of the Ultium chemistry allow GM to use 70 percent less cobalt than GM’s previous generation of EVs.
“GMC has long been a leader in professional-grade trucks and the all-new GMC HUMMER EV will help to establish new standards in capability, maneuverability and driver control,” said Al Oppenheiser, HUMMER EV chief engineer. “Our goal was to develop the most capable, factory off-road pickup on the market."
The HUMMER EV will be the first full-electric vehicle in GMC’s portfolio. The battery cells will be produced as part of a joint venture with LG Chem, at a new facility, in Lordstown, Ohio. Initial production is set to begin in late 2021, at GM’s Factory ZERO, Detroit-Hamtramck Assembly Center.
