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.

I get it. What I don’t get is the 12 kW diesel-powered generator providing 100 miles in 12 minutes. How does the math work out on that? If we are talking about 12kW per hour, then that means only 2.4 kilowatts is transferred to the vehicle in 12 minutes. At 300 miles of total range, that would mean 2.4 kilowatts is 1/3rd of the entire battery. The entire battery is more than 7.2kW in size.
Apologies, the original post was not clearly worded. The 12 kW diesel-powered generator can provide limited charging, while upwards of 100 miles of range can be gained in 12 minutes when plugged into a DC quick-charge source. The post has been updated.
Thanks for the update. That makes perfect sense now. If it’s a 200kW battery like in the regular Hummer EV, then the diesel generator would take approx. 6 hours to produce 100 miles. For a split second I was starting to wonder if GM was keeping the good stuff from us, lol.
Silent running would be a tactical advantage, cool.
Another prohibitively expensive “thing” to sell to our ever-increasing military budget. Even though they’re silent, they will still be noticed by means other than heat detection.
Also, for the price of one of these wonder HMMEVs, other countries will build 50 ICE models that are just as capable and won’t leave their service members stranded in the middle of an op. #EVwunderwaffe
Lithium batteries never burn when punctured by small arms fire. DC fast chargers are always available in the battlefield. You have hours available to charge when the enemy is coming in minutes.
The enemy won’t simply refuel in minutes with a few Jerry cans while you are completely SOL waiting for a charge using a diesel generator.
Drive soldiers where? Along the beach at Daytona? This is strictly an on base vehicle. And that base is no where near a battlefield since it has zero armor and no 240 volt chargers around to keep the thing running. It’s simply an on base transport vehicle. Doors and a roof would certainly be appreciated for those rainy, cold days that troops might actually have to leave the barracks.
Malibu GI Joe?
Bwahahahaha!!! Wait….what? They’re serious?
How many wanna bees pending to be military will be purching these to go get Starbucks coffee in morning..
I guess around base ? Only place you can use that .Way too many openings . At the point just get gmc van . To haul people etc
