Eager to satisfy those who believe that too much horsepower is never enough, Hennessey Performance Engineering has introduced an uber-Corvette in the form of the 2010 ZR1-based Z700. The American tuner claims that the track-orientated Z700 is to the Corvette what the GT3 RS is to the Porsche 911 and the ACR to the Viper. To be produced in a limited run of 24 units for the 2010MY, the Z700 features an array of performance enhancements including an upgraded version of the ZR1’s LS9 V8 engine.

The upgraded supercharger, exhaust and air induction systems help lift output from 638 horsepower to 705 horsepower at 6,400 rpm and peak torque to 717 lb-ft at 3,200 rpm. The result is a zero to 60mph (96km/h) sprint time of just 2.9 seconds while the quarter mile is covered in 10.6 seconds at 134 mph. The standard 2010 Corvette ZR1’s times are 3.4 seconds and 11.3 seconds at 131 mph respectively.

And if that ain’t enough, Hennessey also offers two optional power kits that boost output to 775HP and a massive 1,000HP.

Additional mods on the Z700 include a set of lightweight carbon fiber wheels wrapped in Michelin Pilot Sport Cup tires, which Hennessey says reduce rotating weight by nearly 60 lbs, a lowered suspension and a new aero parts such as the carbon fiber front splitter, canards and rear spoiler that are said to add over 300 lbs of downforce.

Inside, the tuner has upgraded the ZR1’s cabin with lightweight carbon fiber seats and Alcantara steering wheel and shift knob.

The price for the basic Z700 including the 2010 ZR1 donor car has been set at $207,150 US or at today’s exchange rates, €149,312. That’s almost double the price of the factory 2010 Corvette ZR1 638HP that starts from $104,920 and four-times the cost of the basic Corvette Coupe 430HP V8 that begins from $49,515.
