There are two things that almost everyone immediately thinks of when they hear the word “Hummer.” And they are of off-road size and capability. Looking at the numbers on the 2022 GMC Hummer EV, it appears the electric pickup has literal truckloads of each.
One of the most prodigious numbers is the width of the truck. See those ceiling clearance indicator lights? They are not only there for style, they are required by law due to their width. At 86.7 inches, it’s slightly wider than a Ford F-150 Raptor, which is 6.4 inches wider than a comparable F-150. The Hummer is also 5.5 inches wider than a GMC Sierra.
The length is more reasonable at 216.8 inches, which is much less than a full-size double cab pickup (a Sierra 1500 measures 231.7 inches with its 5-foot-8-inch bed or 241.2 with its 6-inch bed. feet 6 inches). It’s even 3 inches shorter than the Raptor SuperCab and just 4.4 inches longer than a GMC Canyon with the standard 5-foot-2 bed. In other words, the Hummer EV is about as long as a midsize pickup, but wider than a heavy-duty truck.
What does that mean for the cabin? With 38.9 inches of rear legroom, it falls far short of 43.4 for a Sierra Crew Cab, but it’s important to remember that double cab pickups have an exaggerated amount of limo-like legroom. The Hummer stock is still 3.7 inches longer than a Sierra Double Cab and 3.1 inches longer than a Canyon Crew Cab. Headroom, which was pretty pathetic in the old Hummer H2, is 38.6 inches in the back seat, less than its two GMC trucks, but not much. In other words, there should be a lot of room back there.
Although it is large, the Hummer has many features that make it agile off-road, both traditional and high-tech. One of the main features is the height adjustable air suspension, which offers 13 inches of travel and automatically adjusts the damping according to the driving conditions. It has three main levels, a lower setting for Aero mode that helps improve energy use on the road, a default height for normal riding modes, and a higher setting for off-road mode. A pull mode will also be added with a later software update that can raise the truck an additional 6 inches for particularly high or deep obstacles, although it is likely to have limited speed, as that height would leave the drive axles at extreme angles and the Very stiff suspension to maintain height. This also means that ground clearance and other distances vary, which is why we list them below in normal, Terrain, and Extraction modes. It’s also worth noting that these numbers only apply to Hummer electric vehicles with air suspension. Base models will have a fixed steel suspension.

Another advantage not only for off-road driving, but for driving in general, is the four-wheel steering system, which is included in all models except the base model. You’ve probably already seen the Crab Mode system that spins the wheels in parallel up to 10 degrees to move diagonally. It can be useful to get away from a nearby obstacle, such as a body bending rock. But it also has features previously seen with Quadrasteer on the mid-2000s GMC Sierra Denalis. At low speeds, the rear wheels can turn in the opposite direction to the front wheels for a turning circle of 37.1 feet instead of 44, 3. This is great for both narrow trails and parking lots. At highway speeds, the rear wheels add small amounts of parallel turn for added stability.
For traction, the Hummer EV has front and rear lockers. On two-engine models, each end has a mechanical locking differential that is activated electronically by the driver. On three-engine models, the single front engine receives the electronically activated locking differential. But since the dual rear motors each control a single wheel, the speed differences are managed by the motors rather than a differential. This means that they can be synchronized to lock effectively, or they can apply different amounts of torque to each wheel (torque vectoring).

Besides torque vectoring, there are other nifty tricks for the powertrain. To prevent axles from breaking as a result of heavy torque applied at acute angles from the steering linkage and suspension, the Hummer will adjust the maximum amount of torque applied based on those axle angles. As with other electrified cars from GM, strong regenerative braking with multiple levels is available. There is also a special calibration for Terrain mode, which allows low-speed driving with a single pedal.
Finally, the Hummer EV has many adaptations to monitor, control, and even upgrade the truck. The infotainment system can display lean and roll angles, tire pressure, torque application, and even multiple exterior camera angles, even under the truck to get around obstacles. Sometimes you’ll want to lower your tire pressure off-road to improve traction, and to help with that, you can tell the truck what pressure you want, and then you can get off the truck, start to release tire pressure, and the truck. it will. audibly alert you when pressure has been reached. The infotainment system has the ability to control aftermarket accessories with virtual toggle switches, and while the Hummer comes standard with 35-inch tires, there’s room to add larger 37-inch tires. GMC also says there will be more than 200 accessories available for the truck directly from GM, such as wheels with bead lock capabilities.
