Chevrolet Corvette ZR1

An all-new LS9 motor produces 620 horsepower at 6500 rpm and 595 pound-feet of torque at 4000 rpm, delivering 100 horsepower per liter, the supercharged 6.2-liter V8 is a close-ratio six-speed manual gearbox with a new high-capacity clutch designed for the increased power. The twin-disc 260mm design provides plenty of clamping power, while maintaining a relatively easy clutch action.

GM has not disclosed specific performance numbers, but the company admits a top speed of 200 mph. In terms of acceleration, the ZR1 most definitely beats its Z06 counterpart,all because of the 115-horsepower output advantage. Since the Z06 rockets to 60 mph in just 3.6 seconds, it's a safe bet the ZR1 will be much closer to the 3.0 seconds.ZR1 clearly beats Z06 in this area.

"It all boils down to the power-to-weight ratio and the ZR1’s is exceptional," said Chevy's Ed Peper. "Better than the Porsche 911 GT2, the Ferrari 599 and even the Lamborghini LP640. In fact, the ZR1 is expected to be the first production Corvette to achieve a top speed of at least 200 mph."That is like 320 km/hr.

GM used the Z06 chassis as a starting point, but further tuned the front and rear independent suspension to work with the ZR1's ultra-wide tires for increased grip. According to GM, the car achieves 1g cornering grip.

Astonishing Looks and materials
The use of carbon fiber is pretty extensive throughout the ZR1. The wider fenders are made of the material, as are the hood, roof panel, roof bow, front fascia splitter and rocker moldings.

The roof and front fascia splitter have a raw carbon fiber appearance with a protective clear coat. The hood is painted like the rest of the car, but the underside is exposed carbon-fiber-weave for increased novelty,which makes the car look stunning.

Another standout feature of the hood is a clear polycarbonate "window" that provides a view of the top of the engine’s intercooler, with embossed "LS9 Supercharged" lettering.

Suspension

The ZR1 comes with GM's Magnetic Selective Ride Control (MSRC) suspension system. The MSRC shocks are automatically adjusted based on driving conditions and vehicle dynamics (cornering, braking, etc) for optimal handling. The system is adjusted every milisecond to provide sharp handling during spirited driving, and a smooth ride while cruising.

While the ZR1 is overall a more aggressive sports car than the Z06, it is actually less harsh over bumps, because of the MSRC technology. “The damping control of MSRC allowed for front and rear springs that have a slightly lower rate than the Z06, which enhances the car’s ride quality,” said Tadge Juechter, Corvette chief engineer.


Interior features

There is very little optional equipment on the ZR1. Aside from the aforementioned chrome wheels, the only other optional equipment is a premium interior package. The kit includes power-adjustable leather-trimmed sport seats, leather-wrapped interior elements (including the dashboard), a navigation system, and Bluetooth Connectivity. The interior leather treatments are available in four colors.
