GM Defense shows electric military concept vehicle based on Hummer EV

General Motors' electric Hummer — a nameplate with military roots — is the foundation for GM Defense's Electric Military Concept Vehicle.

The GM subsidiary introduced the vehicle,, based on the GMC Hummer EV pickup, in June at the Modern Day Marine expo in Washington, D.C. Built on GM's Ultium battery platform, the military vehicle has a 24-module double-stacked battery pack that provides more than 200 kilowatt-hours of power and a GM-estimated range of more than 300 miles, according to the automaker.

A three-motor propulsion system offers two rear motors and a single motor in the front and produces a GM-estimated 1,000 hp and 11,500 pound-feet of torque — similar to the 2023 Hummer EV pickup for retail buyers.

The vehicle is equipped for off-road use, including performance shocks, 37-inch tires and improvements in approach and departure angles. It offers an onboard 12-kilowatt diesel generator, which GM says can generate electricity to charge EV batteries. Externally, the concept can add about 100 miles of range in roughly 12 minutes on a DC fast charger, GM estimates.

The six-passenger concept "enables Silent Watch and Silent Drive, enhancing capabilities with low acoustic and thermal signature, and offers substantial exportable power for mission critical equipment and dash speed through instantaneous high-end torque," GM Defense said.
