Electric Hybrids for Off-road Vehicles - Aggressor, Renegade

Think of an “off-road” vehicle, and billy goat four-by-fours usually come to mind — the ones that chug along using muscular John Deere-style powerplants or diesel engines.

Electric motors? They’re for golf carts, or sissified urban commuter boxes and not for brawny rock crawlers, right?

The leading off-road manufacturers beg to differ. Judging by the concept cars shown by Jeep and Land Rover at this year’s Detroit auto show, they think electric motors do have a future in their vehicles.

The Army agrees on the potential of electrically driven vehicles and has a contract with Quantum Fuel Systems Technologies Worldwide to develop a diesel-electric Alternative Mobility Vehicle, or “Aggressor.”

Like civilians, the Army wants to cut fuel use, because fuel constitutes 70 percent of the materiel it moves into combat zones

Jeep’s Renegade concept, shown for the first time at this year’s Detroit show, examines the possibility of the company making the logical step into dune buggy-style vehicles — small, open vehicles with fat tires pushed to the far corners

Electric power is perfectly suited for off-roaders, according to Doug Quigly, executive engineer for Jeep’s environmentally responsible vehicles.
