GMC HUMMER EV Kicks Off Winter Testing

We have anxiously been awaiting the all-electric Hummer EV from GMC and we now have proof of working test mules.

Rumors surfaced mere hours after the online reveal that there were actually no working copies of the supertruck, which had some worried about GM's promised first deliveries of fall of 2021. These test mules help signal that GM is on-track to have the vehicle ready for those who pre-ordered an Edition 1 for a mere $112k.

The GMC HUMMER EV has arrived at GM’s Milford Proving Grounds to continue validation tests and will head to northern Michigan to run through the team’s grueling winter testing process. We will document the journey and share updates in the coming weeks and months. The HUMMER EV’s development speed was enabled by extensive virtual testing, which will be a hallmark of GM programs moving forward and it will begin initial production in Fall 2021.
