There was a time not too long ago when 1,200 horsepower was the sole domain of purpose-built drag cars. The idea of being able drive a car with a four-figure power number was nearly unthinkable — and now, 600-plus horsepower barely bats an eye. Chevrolet's top-line Camaro is the ZL1 1LE, which ships with 650 horsepower and a track-focused suspension that has proven capable of beating the best from Germany and Italy on the track, but great is never good enough for Hennessey. They've taken the ZL1 1LE and added their tested magic, upping output to 1,200 horsepower and 1,000 ft-lb of torque, thanks to a larger supercharger and strengthened internals mated to a 10-speed automatic. 0-60 MPH disappears in 2.3 seconds and the top speed is 220 MPH — numbers that were once the exclusive domain of European hypercars.
