The Corvette ZR1 is already one of the fastest production cars at 638 bhp, however Hennessey Performance Engineering has raised the level to 705 bhp. Too much horsepower is never enough, even for the all new 2010 Corvette ZR1 that pushes 717 ft-lbs of torque at 3,200 rpms from the rear wheels. The extra power upgrades were accomplished by adding a new supercharger, ECU tuning, air intake, and performance exhaust system. The Corvette ZR1 received lightweight carbon fiber rims wrapped in Michelin Pilot Sport Cup tires, reducing the rotating weight by 60 lbs. A Z-Aero carbon fiber front splitter was installed, along with canards and a rear spoiler supply over 300 lbs of down force to the rear of the vehicle.
