GM Defense has unveiled a new tactical military truck which features a hybrid diesel-electric powertrain for an innovative approach to modern warfare. The prototype was put on display during AUSA 2024 last week in an attempt to woo the United States Army into moving toward commitment on a production version.
Learn more about the innovative Rook.
As you can probably tell from the photos, the vehicle uses the Chevy Silverado 3500 HD ZR2 as a base. Under the hood is a 2.8-liter Duramax turbo-diesel engine. Electric motors for the front and rear axles, plus a 12-moduel battery pack can work in concert with the internal combustion engine or be engaged separately for silent operation, minimizing the risk of detection by enemy combatants.
Using the electric motors also results in a lower thermal signature, helping to prevent infrared detection. Of course, the hybrid system also extends the truck’s range well beyond one with just the diesel engine can achieve. Plus, the battery pack can be used to charge mission systems in the field.
Modern onboard technologies include a 360-degree camera system, roll-over protection, anti-lock brakes, and electronic stability control. Soldiers are secured by four- or five-point safety harnesses, just in case the truck does roll during an operation.
But the most advanced part of the prototype is the claimed ability to make the truck fully autonomous for unmanned missions. After what we’ve seen not only air but also water and land drones do in Ukraine, that might pique some interest.
There’s been plenty of talk about the future of modern warfare and what that means for vehicle designs, including using alternative propulsion systems. However, it’s worth noting that in the past, as early as before WWI, engineers have tinkered with hybrid powertrains to varying degrees of failure.
But with recent developments in technology, especially when it comes to batteries, some feel hybrids have finally become practical not only on public roads but also on battlefields. We’ll see if the powers that be in the United States Army and other militaries agree with that sentiment. And if they do, we’ll see how successful of a venture such a thing might be.
Perhaps this prototype has already started discussion which might lead to the creation of a unique tactical vehicle inspired by this design.
