Army’s Diesel-Electric ‘Aggressor’ Vehicle Could Be Iraq’s First Hybrid

Army’s Diesel-Electric ‘Aggressor’ Vehicle Could Be Iraq’s First Hybrid

The diesel-electric hybrid hype has met its match: the U.S. Army. After focusing on hydrogen fuel cells in its original version of “The Aggressor,” a high-performance, off-road Alternative Mobility Vehicle (AMV) for military ground exploration and scouting missions, the Pentagon is now going the way of Detroit—with batteries.

The new, second-generation prototype will still utilize the same basic chassis and exterior design for light-duty capacity. But the Army’s auto research arm—part of the Tank Automotive Research, Development and Engineering Center (TARDEC)—has developed a battery-dominant, hybrid-electric drivetrain with a diesel engine-generator. That could make the new Aggressor the first hybrid to hit the streets of Baghdad en masse.

A wider, 66-in. body design makes room for high-performance acceleration—as military vehicles go—with the second-gen Aggressor set to rev from 0-40 mph in four seconds and top out at 80 mph. But speed is not the main attraction here; stealth is. The Aggressor’s design provides battery-only operations, allowing it to switch into “silent mode” with a reduced thermal signature. Combine that with extended range and exportable power, and this should be one tough-to-detect AMV for missions involving communications, surveillance and targeting.

While the first prototype, built in 2004, never made it beyond military testing and evaluation, the new pre-production Aggressors aim to be energy- and mission-sustainable. “We believe that the AMV program offers an innovative solution as a long-range reconnaissance vehicle that fills a technology gap for the U.S. Army in its national defense efforts while reducing its fuel logistic burden,” said Alan Niedzwieki, president and CEO of Quantum Fuel Systems Technologies, which the Army contracted for both versions of the Aggressor.

There have also been internal discussions about the benefits of the Aggressor and Quantum’s innovative, hybrid drivetrain for other commercial applications, including homeland security, border patrol, park service operations and light-duty automobiles. A military-powered hybrid future? Now that’s one for the comments section.... —Brittany Marquis
