GM Hummer EV vs Sub-Zero

Flawless Victory

Before any GMC vehicle like the Hummer EV reaches customers’ driveways, it gets tortured rigorously tested to prove the extent of its capability.

First up: Winter testing in Michigan’s Upper Peninsula, where the GMC Hummer EV team put this supertruck through its paces in sub-zero temperatures on various slippery surfaces, including snow, ice, steep and split-mu grades.

Key tests include integrating its powerful all-wheel drive torque distribution with the traction control system, as well as calibrating and testing the electronic stability control system.
