What does it take to beat the almighty McLaren 720S in a rolling drag race? A serious amount of power, that’s what.
Hennessy Performance builds some of the fastest vehicles on the planet and recently lined up their Corvette ZR1, complete with their HPE1200 package, alongside a stock McLaren 720S.
A recent dyno run of the Corvette ZR1 in question revealed that its beefed-up supercharged 6.2-liter V8 pumps out 1139 hp and 994 lb-ft (1348 Nm) of torque to the rear wheels. By comparison, the 720S makes 710 HP and 568 lb-ft (770 Nm) at the crank, although, as it has been proven many times, that those figures are rather conservative. Nevertheless, the British supercar has a significant power deficit.
Thus, it’s hardly surprisingly that the ZR1 was able to take the victory without really breaking a sweat. However, the McLaren has to be commended for its effort, because it wasn’t all that much slower than the heavily-modified ZR1 as their respective power figures might suggest – and around a circuit, it might just have been able to keep up.
Interestingly, Hennessey also offers a host of upgrade packages for the 720S as well, including its range-topping HPE1000 package which, as the name implies, lifts grunt to 1000 hp thanks to upgraded turbochargers, stainless steel headers, a tweaked ECU, and improved transmission. If a HPE1000-equipped 720S were to race against the HPE1200 Corvette ZR1, then it would be a much more fair fight – and one we’d be very willing to watch.
