GMC Tests HUMMER EV in Sub-Zero Conditions, Announces HUMMER EV SUV Reveal Date


Before any GMC vehicle reaches customers’ driveways, it undergoes a rigorous test and validation schedule to prove the extent of its capability. Follow the GMC HUMMER EV on its testing and development journey as a team of engineers visits locations across the U.S. to tune the GMC HUMMER EV in the lead-up to its production debut this fall. 


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.
