The GMC Hummer EV undergoes cold weather trials

Before any GMC vehicle reaches a customer's driveway, it undergoes a rigorous test and validation schedule to prove the extent of its capability.

Follow the Hummer EV on its testing and development journey as a team of engineers visits locations across the United States to tune the Hummer EV in the lead-up to its production debut later in 2021.

First up, winter testing in Michigan's Upper Peninsula, where the 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.
