GM Defense Introduces Tactical Vehicle Combining Diesel and EV Technologies

A newly revealed prototype by GM Defense introduces a tactical vehicle that combines the stealth of an all-electric powertrain with the fuel efficiency and high torque of a diesel engine. Referred to as the “Next Gen,” this four-door pickup is built on the framework of the Chevrolet Silverado 2500HD ZR2, though it offers much more than a standard truck.

Designed as an extended-range electric vehicle (EREV), it draws comparisons to the forthcoming Ram 1500 Ramcharger. However, instead of relying on a gas-powered V6 engine to generate electricity, GM Defense equipped the Next Gen with a 2.8-liter Duramax turbo-diesel engine to extend battery range.

The vehicle’s power system consists of a 12-module battery pack that drives two electric motors—one positioned at the front and another at the rear. While the specific range for electric-only driving has not been disclosed, the inclusion of a diesel engine to generate power ensures operational flexibility wherever fuel is accessible.

This powertrain setup enables the Next Gen to perform Silent Drive and Silent Watch operations, allowing it to move into sensitive areas undetected and observe without using fuel. Additionally, the diesel engine’s low thermal signature makes it more difficult for enemies to detect the vehicle with infrared sensors when the engine is not running.

With its 12-module battery—likely built using Ultium EV technology—the truck can export electrical power to run high-energy systems such as sensors. The vehicle, derived from the road-going Silverado 2500HD, also includes safety features like rollover protection, anti-lock brakes, electronic stability control, four- and five-point harnesses, and a 360-degree camera system.

GM Defense highlighted that the EREV consumes less fuel compared to traditional military vehicles and can operate using the existing JP8 kerosene-based fuel infrastructure. Designed with modularity in mind, it can be equipped with additional armor and supports both manned and unmanned operations, thanks to integrated autonomous technology.

Offered in two-, four-, and six-seat versions, the battery-powered pickup is tailored to handle a variety of missions. These include command and control operations, network extension, counter-unmanned aerial systems, anti-armor tasks, casualty evacuation, and other critical roles essential for modern military engagements.
