Hummer EV CrabWalk is a four-wheel-steering mode that lets the electric GMC Hummer move diagonally at low speed, with the rear wheels steering in the same direction as the fronts. GM describes the rear wheels turning up to roughly 10 degrees, and it is standard on the Edition 1 and the EV2X.
How Hummer EV CrabWalk works
In normal driving the Hummer’s rear wheels turn opposite the fronts to shrink the turning circle. In CrabWalk mode they turn the same way, so the truck slides diagonally instead of pointing where it travels.
It is meant for slow off-road moves, such as getting around an obstacle or a trail rut, and works only at low speed. Check the owner’s manual for the exact speed limit and trim availability.

CrabWalk limitations to know
- It is a low-speed off-road tool, not a highway feature.
- The truck is very large and heavy, so allow lots of room around you.
- Not every trim includes it, so check the build sheet before you buy.
