Last month, General Motors released a video showing a pre-production GMC Hummer EV prototype doing a donut in the snow at its Milford Proving Ground test center in Michigan. Now, the automaker has released another clip showing the GMC Hummer EV playing in the powdery Michigan snow – but this time, the automaker demonstrated how its innovative CrabWalk mode works in the white stuff.
The GMC Hummer EV’s CrabWalk mode allows the vehicle to move diagonally on loose surfaces like dirt, sand or snow. When activated, the Hummer’s four-wheel-steering system will point all four wheels in the same diagonal direction. At the same time, the four-wheel-drive system will slowly turn all wheels at the same speed, allowing the vehicle to shift across the surface. The technology can be used for navigating difficult terrain or freeing the vehicle if it becomes stuck in a rut, deep snow or mud, for example.
CrabWalk mode is made possible thanks to the GMC Hummer EV’s four-wheel-steering system, which also improves the vehicle’s low-speed maneuverability and high-speed stability. Between this 4WS system, standard 4WD and technologies like CrabWalk mode, the GMC Hummer EV is hoping to convert internal combustion engine off-road truck fans to the green side. The tri-motor powertrain setup that comes in the GMC Hummer EV First Edition will also help entice traditional truck fans, producing 1,000 horsepower and enabling the truck to accelerate from zero to 60 mph in just three seconds.
The GMC Hummer EV First Edition will enter production at the GM Factory Zero plant later this year. For now, though, be sure to check out the video embedded below to see the electric pickup truck’s CrabWalk mode in action in the snow.
