2010 Hennessey Corvette Z700

With Hennessey’s Z700 upgrade package, the Corvette ZR1 becomes even better. The priciple behind the kit is improved performance through comprehensive upgrades both inside and out. Supercharger modifications include an increase in boost to 15 psi that help the car produce 705 hp @ 6,400 rpm. Furthermore the exhaust and intake tracts are new. To complete the package a new bodykit is available, as is carbon fiber wheels and an Alcantara interior.

Press Release

July 7, 2009, SEALY, TX – The world’s fastest and most powerful production Corvette, the 638 bhp ZR1 has become the pinnacle of American sports cars. For most ZR1 owners, having a car capable of Nürburgring times of 7:26 is more than enough performance to satisfy their need for speed. However, for the select few who subscribe to the mantra of “too much horsepower is never enough”, Hennessey Performance Engineering (HPE) has something special in store for them in 2010. HPE is happy to introduce the company’s 705 bhp Z700 upgrade package for the 2010 ZR1.

Porsche 911 owners wanting the uber Porsche can order the GT3 RS. Dodge Viper enthusiasts wanting the ultimate road race Viper have the ACR. Now ZR1 owners can opt for the Hennessey Z700 upgrade for their Corvettes.

Hennessey’s Z700 performance package starts by upgrading the LS9’s supercharger, exhaust and air induction systems, which is then dyno tuned to 705 bhp. But this is just the beginning. Additional upgrades include lightweight carbon fiber wheels with Michelin Pilot Sport Cup tires, which reduces rotating weight by nearly 60 lbs. Hennessey’s Z-Aero ™ carbon fiber front splitter, canards and rear spoiler also add over 300 lbs of downforce, helping plant the added power to the road or track. Rounding out the Z700 upgrade package is a revised interior with lightweight carbon fiber seats, Alcantara steering wheel and shift knob.

HPE will be throwing its hat into the Ring – literally – with plans to begin testing the Z700 at the famed Nürburgring in Germany later in 2009. The company plans to build just 24 of these limited-edition Corvette ZR1’s for the 2010 model year. Each customer also gets a full day of performance driving instruction in his or her new Z700 at Hennessey’s own private test track, Lonestar Motorsports Park. Lonestar, which is located next to the company’s facility, is located just west of Houston, Texas and has a full quarter-mile dragstrip as well as the addition of a 1.1-mile road course which will soon be under construction.
