The Corvette ZR1 offers a performance of 0-60 mph in 0.3 secs, which is quicker than the already-quick Corvette Z06. The 0-100 mph performance is nearly a full second quicker (7 secs) compared to the Z06's 7.9 seconds. The Corvette ZR1 was turning in lap times in the low 7:40s, a pace that puts it right up there with the world’s fastest supercars. And given the damp conditions and rough, hand-timed numbers, you can expect to see even quicker official lap times when Chevrolet goes public with its Nurburg data. The Corvette ZR1 also has a top speed of 205 mph, making it the fastest and most powerful Corvette ever produced. The LS9 engine is teamed with a new, stronger six-speed manual transmission and a twin-disc clutch that provides exceptional clamping power, while maintaining an easy clutch effort.

Carbon fiber, a material first used in the racing world, has the advantage of weighing 50% less than steel. Although it is expensive, carbon fiber could be the answer to bringing down body weight, a crucial component in meeting the new federally mandated standards for higher fuel efficiency. Carbon-fiber domed hood with a window to the supercharger Unique carbon fiber dual cove front fenders. With its 638 horsepower LS9 supercharged V8 the Corvette ZR1 is capable of 205 mph on the test track. Carbon-ceramic brakes from Brembo provide the kind of stoppage you'd expect from an arriving 737.

Power is expected to be 620 bhp (462 kW) and torque 823 Nm (607 lbft). This is transmitted to the rear wheels via a new six-speed manual gearbox and twin-plate clutch. Power has to come from somewhere, and in the ZR1’s case its the added air through supercharging.

Engine management controls secondary induction system operations. The driver has a manual override in the form of the ZR1's famous valet switch or power key. neers are confidant that the ZR1 will be the most fuel efficient 600 horsepower super-car on the market. If GM makes there goal of 3350 pounds that will put the Corvette just behind the Ferrari Enzo when it comes to weight-to-power ratios, and a ways ahead of the Lamborghini Murcielago LP640.

GM Powertrain testing shows the engine makes approximately 300 horsepower (224 kW) at 3,000 rpm and nearly 320lb.-ft. Torque tops 585 lb.-ft.(793 Nm) at about the 4,000-rpm mark, while horsepower peaks at 6,500rpm. GM says they save 11 pounds at each corner compared to cast iron rotors. Six-piston front and four-piston rear calipers will be used; the front brake pads will be twice the size of those found on the Z06. GM says that the Corvette ZR1 will be capable of breaking the 60 mph barrier in only 3.4 seconds and reaching a 100 mph mark in exactly 7.0 seconds. It may still look a little bit sluggish if you compare it to Bugatti Veyron , but at a price of only $103,000 it is 15 times cheaper, too.

Exposed carbon-fibre is used on the roof, roof bow, rocker molding and front splitter. These exterior components are protected by a specially developed glossy, UV-resistant clear coat that resists yellowing and wear.

And the 0-100mph performance is nearly a full second quicker: 7 seconds vs. The Corvette ZR1 has grown from 300hp ten years ago to about 630 hp today.
