Think the Covette ZR1 was a bit undercooked when GM served it up? 638 HP not enough for you? Call the folks at Hennessey Performance and they'll cook up a Nurburgring-tested 705HP ultra-ultra Corvette Z700.

Sure, 705 HP and a 2.9 second zero to sixty time is one thing to brag about, but that's not the brass ring Hennessey is going after with the Z700. They're taking this ZR1 upgraded with even more carbon fiber goodies like super-light carbon fiber wheels, seats, and an aero-kit that develops 300 lbs of downforce at speed and a healthier supercharger and bigger exhaust for a scream around the Nurburgring, aiming at the Corvette ZR1's 7:26 lap time.

It's worth the extra second to read all the way to the bottom of the press release to see the "optional upgrades" which include the "Z750" package, good for 755 HP, and the modest Z1000, which is not a 70's Kawasaki, but a 1000 HP ZR1. We'll be waiting on the edges of our seats to hear more about that tire liquification system.

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 Nurburgring times of 7:26 is more than enough to satisfy 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 Nurburgring 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.
