You can trace the lineage of the original Hummer H1 back to AM General’s High Mobility Multipurpose Wheeled Vehicle, or Humvee, a military-spec truck first put into service in 1983. Now, it looks like the new GMC Hummer EV could reverse the process, with the civvy-spec all-electric off-roader recently redressed as a new electric military concept vehicle, courtesy of General Motors’ military vehicle and technology division, GM Defense. The new GM Defense concept made its debut at the Modern Day Marine 2023 expo, held earlier this week in Washington, D.C.
GM Defense officially calls the new concept the Electric Military Concept Vehicle, or eMCV, and it is based on the GMC Hummer EV Pickup. The concept is intended to demonstrate GM Defense’s “ability to leverage advanced commercial technologies to help global defense and government customers transition to a more electric, autonomous and connected future.”
The new GM Defense eMCV is part of the division’s ongoing Series Hybrid Light Tactical Wheeled Vehicle development. The concept leverages the GMC Hummer EV propulsion architecture, specifically GM’s Ultium Drive electric motors and Ultium battery technology, providing flexibility and adaptability. GM Defense also indicates that the vehicle can use various form factors and chemistries to meet changing needs.
The vehicle provides seating for upwards of six passengers, as well as Silent Watch and Silent Drive modes with low acoustic and thermal signatures. In addition, the onboard systems provide high dash speeds thanks to the instant torque delivery, plus substantial exportable power for mission critical equipment. Specs include a 200+ kWh Ultium battery pack, three-motor propulsion, and 1,000 horsepower, with enough range to cover more than 300 miles. In addition, the vehicle can feature an on-board 12 kW diesel-powered generator that can provide limited recharge capabilities. Plugged into a DC quick-charge source, the vehicle can gain roughly 100 miles of range in just 12 minutes.
Further features include Fox performance shocks, 37-inch tires, heavy duty brakes, and improved approach and departure angles, as well as a 46-inch gun ring and swing side-arm mounts.
In related news, GM Defense recently announced plans to develop a new energy storage system for the DoD, once again leveraging GM Ultium tech.
