When it comes to the American tuners at Hennessey "too much power is never enough." So, if the Chevrolet’s super car, the Corvette ZR-1 develops 638 HP from the factory, what about after a little massaging? Hennessey found a few extra ponies and raised the vehicle’s output to 705 HP.

The tuning package, dubbed Z700, comes with a new supercharger, some ECU tweaking as well as some free flowing exhaust and air induction systems. Henessey added a set of lightweight carbon fiber wheels wrapped in Michelin Pilot Sport Cup tires to maintain their unique grip on the road. A Z-Aero carbon fiber front splitter, canards and rear spoiler all work together to create over 300 pounds of aerodynamic down force for the perfect handling high speed sports car.

With 705 HP and 717 lb-ft of torque coming from the V8, the Z700 is capable of sprinting from 0 to 60 MPH in just 2.9 seconds and will hit 100 MPH in only 6.4 seconds. However the true test of straight line performance is how the vehicle fairs down the 1320. The standing ¼ mile is consumed in 10.6 seconds at 134 MPH, quite impressive indeed.

BMWM6, the Hennessey based GT-R does 0to60 in 2.58. But both are tuned cars, not stock. Plenty of tuned cars can do that.

The 9FF GT2 also does 2.5 in 0to60.

What the ZR1 needs is a better suspension... not more power. 638 hp is already more than most people would ever want.
