Hennessey ZR750 Chevrolet Corvette ZR1



Texan tuning firm Hennessey Performance Engineering is certainly no stranger to over-the-top modified cars, having released a string of 1,000+ horsepower Dodge Vipers in the past and even its own custom supercar powered by a twin-turbocharged LS9 V-8. With such a pedigree, it’s safe to say Hennessey knows a thing or two about extracting big numbers from American muscle.

So, when faced with the challenge of improving on the 638 horsepower Chevrolet Corvette ZR1, instead of questioning why someone would want more power in the first place, Hennessey went about and built a new package for the all-American supercar.

Dubbed ZR750, the new package helps liberate 755 horsepower and a mammoth 728 pound-feet of torque from the Corvette ZR1’s supercharged 6.2-liter V-8. This results in a 0-60 mph time of just 2.8 seconds, a quarter mile ET of 10.3 seconds at 139 mph and a top speed in excess of 224 mph. Note times are listed for cars equipped with new Michelin Pilot Sport Cup tires.

The list of modifications include a new supercharger pulley, which increases boost from 9 to 13 psi, a new air intake, custom cylinder heads, new camshafts, a high-flow exhaust and a full ECU retune.

Of course, the best part is that Hennessey’s modifications come with a 3-year or 36,000 mile limited warranty. Check out the performance of the new Hennessey ZR750 Chevrolet Corvette ZR1 in the videos below.

  1. Obviously, I'd rather drive this 755hp Corvette than the 800hp Ford Mustang GT-500
