If you want a brand new, C7-generation Chevrolet Corvette that offers earth-shattering performance, you have one choice: the Corvette ZR1. However, if the 755 HP Corvette isn’t quick enough for you, there are a number of aftermarket specialists that will be glad to help out – and one of the first names that spring to mind is Hennessey Performance.
Hennessey has named its latest creation the HPE1000 Grand Sport. The car starts out life as a regular Corvette Grand Sport and when it gets to Hennessey it has its 6.2-liter V8 fitted with a massive centrifugal supercharger and an upgraded fuel system that results in a total of 1008 HP at 6500 rpm and 918 lb-ft (1244 Nm) of torque at 4000 rpm.
In a straight-line, the company claims these extraordinary figures allow the HPE1000 ‘Vette to reach 60 mph (96 km/h) in just 2.5 seconds and do the quarter mile in 9.7 seconds at 147 mph (236 km/h). What’s more, the car will top out at 220 mph (354 km/h). Those who know anything about high-performance sports cars will know that these figures are usually reserved for multi-million dollar European exotics.
As standard, the Corvette Grand Sport is perhaps the best bang-for-your-buck model in the Corvette range. The sports car is powered by the same 6.2-liter naturally-aspirated V8 as the Stingray but is fitted with the chassis of the Z06, making for a much sportier ride.
