Corvette ZR1, The Most Expensive Corvette Ever
Chevrolet Corvette ZR1 supercar it is the most powerful and most expensive Corvette model ever. 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 mated to 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 is very likely in this most expensive Corvette. In terms of acceleration, the ZR1 most definitely beats its Z06 counterpart, thanks to a 115-horsepower output advantage. Since the Z06 rockets to 60 mph in just 3.7 seconds, the ZR1 is improved to a quicker 3.4 second zero-to-60 time.
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 ZR1 has the largest wheels ever of any production Corvette — not just in diameter, but in width also. The rims measure 20 inches in rear diameter and 19 inches up front. Rear width is a whopping 12 inches, while the front wheels are nearly as massive at 10 inches of width.
The most expensive Corvette’s braking system features carbon-ceramic rotors measuring 15.5 inches up front and 15 inches at the rear. GM says the rotors are so durable they should not requiring replacement for the life of the vehicle.
While the ZR1 is overall a more aggressive sports car than the Z06, it is actually less harsh over bumps, thanks to 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 most expensive Corvette‘s ride quality.
