A specially outfitted 2006 Corvette Z06 will serve as the official pace car of the 48 th running of the Daytona 500, on Feb. 19. “Tonight Show” host and auto enthusiast Jay Leno will drive the pace car.
The Corvette Z06 that will serve as the Daytona 500 pace car is mechanically identical to those available at Chevrolet dealerships. It is the fastest vehicle ever offered by Chevrolet and General Motors. With 505 horsepower (377 kw) and 470 lb.-ft. of torque (637 Nm) from its 7.0L all-aluminum, racing-inspired engine, the Corvette Z06 leaps from 0-60 mph in 3.7 seconds and has a top speed of 198 mph. It also differs from other production Corvette models with extensive use of lightweight materials, including carbon-fiber front fenders and a chassis comprised of aluminum and magnesium. A racing-ready suspension and large, 18-inch front wheels and 19-inch rear wheels help keep it glued to the tarmac, so it requires no drivetrain modifications to satisfy its role in front of the racing pack. In its official capacity, however, the pace car is outfitted with a variety of safety equipment and highly visible strobe lights. Interestingly, the Corvette Z06’s 505-horsepower (377 kw) output is actually more than the power produced by the race cars that will compete in the Daytona 500 – a first for a pace car. This is because of the unique “restrictor plate” rule established for the Daytona and Talladega , Ala. racetracks. On these 2.5-mile-long super speedways, the restrictor plate reduces airflow into the engine to limit horsepower and keep race car speeds below 200 mph. With a restrictor plate, racing engine power is reduced from about 750 horsepower to about 450 horsepower. Race cars can still average more than 190 mph on Daytona’s long straights. (4 January 2006)
