See the Advance Combat Engine (ACE) in action at Yuma Proving Grounds

The ACE is engineered for operation in full desert conditions using all specified military fuels.

At the US Army’s Yuma Proving Ground in Arizona, ACE recently passed a series of rigorous tests powering the Advanced Mobility Experimental Prototype (AMEP).

The compact 14.3L ACE produces 1,000 hp, and a peak torque of 2424 lb-ft. This four-cylinder, two-stroke, opposed-piston diesel engine is equipped with eight pistons, as well as supercharging and turbocharging capabilities that eliminate the necessity for a valve train.
