It seems Nürburgring lap times are the figures to quote for today’s performance cars. We’re not too surprised, then, to see Hennessy Performance Engineering plans on running its Z700--a tuned Corvette ZR1--around the ‘Ring.
With 638 hp available on tap, the stock Corvette ZR1 isn’t exactly a tame pony — in fact, it’s able to lap the Green Hell in a shockingly low 7 minutes and 26 seconds. Still, for those who crave more power — or, perhaps, an even lower ‘Ring time — Hennessey’s got the goods.
The Z700 package, which includes an upgraded supercharger, intake, and exhaust, bumps the Corvette’s power up to 705 hp and 717 lb-ft of torque. To help keep that power mated to the pavement, Hennessey fits the car with carbon fiber wheels shod with Michelin Pilot Sport Cup rubber, and adds a carbon fiber front splitter, canards, and a rear spoiler, addingmore than300 pounds of downforce when at speed.
The interior hasn’t been neglected—Z700 models receive a number of tweaks designed to cut weight. Both the steering wheel and shift knob are trimmed in Alcantara, while the stock seats are eschewed in favor of a pair of carbon fiber bucket seats
If this sounds like the best way to spend your hard-earned $207,150 — nearly $100,000 over a base ZR1 — Hennessy’s taking orders now for the 2010 model year. Expect Nürburgring times to emerge this fall.
