Factory Zero may be under construction, but GM is already building new GMC Hummer pickups at the high-tech factory. The pre-production vehicles won’t be for sale, but General Motors and the UAW are confident that production units will be available soon. The plant will eventually employ 2,200 people, but just 435 are at work on the early Hummer models.

GM is in the middle of a $2.2 billion retooling effort at the plant, and the automaker expects to deliver the first Hummer EVs from the facility by year’s end. The Detroit-Hamtramck plant was closed in early 2020 after it built the last Chevy Impala. After pressure from the union, GM agreed to overhaul the facility to build EVs. Now called Factory Zero, the facility will build the new Hummer pickup, the Cruise Origin, the Hummer SUV, and eventually, the Silverado electric pickup truck.

The GMC Hummer EV generated strong demand, as GMC recorded around 10,000 reservations for the $112,595 pickup. The GMC Hummer SUV will come later, followed by the electric Silverado. We don’t have firm timelines for either of those vehicles, but GM President Mark Reuss has stated that the Silverado will start production after the Hummer SUV, which should take place early in 2023.
