General Motors is moving up the start of production for its 2027 GMC Hummer EV to November 30, 2026. This adjustment at the Factory Zero plant in Michigan shifts the start date two weeks earlier than the originally planned December 14 schedule.

Why it matters

Updating production timelines helps potential buyers and dealership networks manage inventory expectations for the upcoming 2027 model year. The new model year introduces significant hardware changes, including an integrated NACS charge port and new aesthetic options.

Regular production of the 2027 GMC Hummer EV begins on November 30, 2026, two weeks earlier than the previously announced date. The rollout includes the debut of the ICON | 25 Edition alongside two new 22-inch wheel options and five new exterior colors.
