As with all good things Dodge, the Rampage Concept has the 5.7-liter Hemi in it, and you already know what that means – it flat out hauls, to the tune of 345 horsepower at 5,400 rpm, and 375 lb.-ft. of torque at 4,200 rpm. The engine is connected to a five-speed automatic transmission. Big, oversized 22-inch wheels and an independent front and rear suspension flatten out the road, as does the estimated 5,000 lb. curb weight.
