The all-new 2014 Chevrolet Corvette C7 Stingray hasn't even arrived in showrooms, but that minor speed bump hasn't slowed Hennessey Performance (HPE) from introducing a full suite of packaged (and à la carte) upgrades to the highly anticipated American sports car that will undoubtedly trump even the factory's future high-performance Z06 and ZR1 models.
In base form, the C7's new 6.2-liter V8 will be rated at 455 horsepower. While that's a strong start, Hennessey's first two packages bolt on a TVS2300 supercharger system and other miscellaneous upgrades to find upwards of 150 additional horses (both come with a 3 Year/36,000-mile warranty). The more aggressive packages start with an HPE custom balanced and forged engine that is accompanied by two ball-bearing turbochargers, forged pistons and plenty of other go-fast hardware to deliver up to 1,000 horsepower (both come with a 1 Year/12,000-mile warranty).
The company has announced four different upgrade programs (prices include professional installation):
- HPE600 Supercharged ($12,495) 600 hp @ 6,300 rpm
- HPE700 Supercharged ($18,450) 700 hp @ 6,300 rpm
- HPE800 Twin-Turbo ($54,950) 800 hp @ 6,300 rpm
- HPE1000 Twin-Turbo ($67,950) 1,100 hp @ 6,300 rpm
