The Chevrolet Colorado Rally Concept truck pictured above will most likely not become a reality even thought it looks totally doable. The Colorado Rally Concept truck comes with 4-doors, four-wheel drive, 18-inch rims (305/60 R18), adjustable suspension, a 2.8-liter turbo diesel engine, front and back winches, GPS, vented acrylic side windows, rally racing seats with five-point seatbelts, roll bar, and a Hydration Pack for the thirsty occupants. It kind of reminds me of the oil burning Chevrolet Avalanche, but cooler.
