Chevrolet Corvette ZR1

Power-to-Weight Ratio: 638 hp / 3,324 lbs = .205 0-60 mph: 3.3 seconds Top Speed: 205 mph We start out with the Blue Devil. Pure American power pushes this inappropriately quick Vette into the big leagues. The heaviest beast in the Corvette stable, the ZR1 owes its place on this list to its 6.2-liter LS9 aluminum V8 that’s got a 4-Lobe Eaton Twin Vortices supercharger and intercooler strapped on top and pushes out 604 lb-ft of torque. The supercharger may add a hundred odd pounds on top of the Z06’s curb-weight, but the ridiculous amounts of power it provides in compensation more than makes up for it.
