Hennessey presented three upgrade packages for the new Chevrolet Corvette Z06, although it still has not been released yet.
The 6.2 liter V8 LT4 supercharged engine of the American muscle car, without any modifications produces 650 hp and 880 Nm and it is able to do the 0-96 km/h in 2.95 sec. when it is combined with the 8-speed automatic gearbox and 3.2 sec. with the standard 7-speed manual.
The stage 1 package of Hennessey increases the horsepower to 750 hp @ 6,300 rpm, the stage 2 package makes the engine reach 850 hp @ 6,500 rpm, while the HPE1000 package increases the horsepower to 1,000 hp @ 6,500 rpm.
The increase in horsepower comes from the change of the 1.7 liter Eaton supercharger with a larger one of 2.9 liters.
