(March 11, 2021) DETROIT — 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 super-truck 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.

On April 3, tune into gmc.com at 5 p.m. EDT or the NCAA Final Four as GMC reveals the next chapter in its story — the GMC Hummer EV SUV. Reservations will open for customers on that same date.
