Overland Vehicles

The Hummer EV off road truck was built to tackle technical terrain with a blend of electric torque, four wheel steering, and substantial protection underneath. Its tri motor layout in top trims delivers instant response, while adaptive air suspension and Extract Mode can raise the body roughly six inches to clear ledges or deep ruts. From the factory it rolls on 35 inch tires and 18 inch wheels, with steel plates and skid armor shielding the battery and key components. GMC’s Ultravision camera suite, including underbody views with built in washers, helps pick lines and avoid sharp rocks that can threaten sidewalls.

The four wheel steering system is central to how this truck moves in tight spaces. With rear steer engaged, the turning circle shrinks dramatically, and CrabWalk can shift the vehicle diagonally to slide past boulders or narrow pinch points. Approach, breakover, and departure angles are competitive for a full size platform, aided by tall tires and short overhangs. In standard ride height the truck already sits high; in Extract Mode it gains serious ground clearance for brief obstacles where belly height is critical.
Adaptive air suspension changes ride height and character on the fly. Paired with large diameter tires, it smooths chatter and allows lower pressures for traction on slickrock or sand. Owners who consider 37 inch fitments should account for added mass, possible trimming, and the energy penalty. Larger rubber can help on deep ruts, but careful sizing and wheel offset choices keep steering geometry and range in check.
Drive modes tune pedal mapping, stability logic, and the one pedal Terrain Mode that makes slow crawling intuitive. With three motors available in top trims, torque vectoring can help simulate locker behavior by sending torque where it can be used. The system’s precision is helpful on staggered ledges, cross axle situations, or slick climbs where momentum needs to be minimized.
Factory skid plates and rock shields protect the battery and underbody in hits that would sideline many trucks. Recovery points are integrated, though the curb weight is significant, so recovery gear selection should reflect real loads. Ground clearance in Extract Mode is a short duration tool rather than a cruising height, best used to get past a single obstacle before returning to a normal setting for stability and range.
On paper the Hummer EV off road truck offers a highway range that can exceed 300 miles depending on configuration. Trail use is different. Low pressure tires, elevation change, soft surfaces, and frequent accelerations can raise consumption. Budget conservatively for off road sections, and lean on regen for controlled descents where the system can recover energy without overheating brakes.
The 800 volt architecture supports high rate DC fast charging on compatible stations, often quoted around 350 kW peak in ideal conditions. That makes road transfers between trail systems more practical, with brief stops adding meaningful miles. On backroads without fast charging, plan overnight Level 2 sessions and carry a clear plan for charge points near trailheads.
This truck is wide and heavy, which comes with tradeoffs. It feels planted on slickrock but can sink quickly in deep sand at low pressures and may require careful weight distribution in the bed. Towing and payload limits should be respected, especially with added armor or gear. Balance spare tire mounts, tools, and storage to keep the center of gravity low and predictable.
If you want to translate the Hummer EV’s hardware into a cohesive overland setup, focus on the essentials that preserve range while improving functionality. Rock protection, lighting with efficient draw, sealed storage, recovery gear sized for the truck’s mass, and roof or bed systems that do not fight aerodynamics are smart starting points. Communication upgrades matter for remote travel, and integrated power management should be planned with charging stops in mind.
For drivers mapping extended dirt routes, an experienced build partner can plan upgrades that align with the platform’s strengths.
