Known for their charismatic designs and superior performance, the pack-leading pace cars share a special place in Indianapolis 500 lore. History will be made at the 2008 Indianapolis 500 when a pair of distinctive yet highly differentiated Corvette models will serve as the official pace cars – one highlighting Chevrolet’s commitment to fuel solutions and the other marking 30 years of Corvette’s pace car heritage. Chevrolet and Indianapolis Motor Speedway officials gathered at the Indianapolis Auto Show to make the historic announcement.

One of the pace cars is a customized Corvette Z06 E85 concept that runs on E85 ethanol fuel, a domestically produced alternative fuel similar to the E100 fuel that powers all of the racecars in the IndyCar Series. It will be driven during the race’s pace lap by two-time Indianapolis 500 champion Emerson Fittipaldi.

The other official pace car is a black-and-silver commemorative edition that marks the 30th anniversary of the celebrated 1978 pace car – the first Corvette to pace the field at the Indianapolis 500. Chevrolet will produce a total of 500 pace car replicas in both coupe and convertible form, each signed personally by Fittipaldi at the Corvette’s Bowling Green, Ky., assembly plant.

''Although not a production FlexFuel vehicle, the Corvette Z06 E85 concept pace car is a high-performance example of Chevrolet’s gas-friendly to gas-free initiative, demonstrating viable fuel solutions,'' said Ed Peper, Chevrolet general manager. ''As an ethanol refiner in his native Brazil, Emerson Fittipaldi is the fitting Chevrolet champion to help support GM’s efforts with E85 and celebrate 30 years of the Corvette pacing the Indianapolis 500.''

The 92nd Indianapolis 500 takes place on Sunday, May 25, 2008. It will be the Corvette’s 10th appearance as the official pace car – a record unmatched by any other vehicle. ''It’s only fitting that Corvette will be the first car to earn the distinction of having two models pace the Indianapolis 500 in the same year,'' said Joie Chitwood, Indianapolis Motor Speedway president and chief operating officer. ''Chevrolet and Corvette are a vital part of the rich history of ‘The Greatest Spectacle in Racing,’ and we’re honored to have a great champion of the race and of alternative fuels, Emerson Fittipaldi, as this year’s pace car driver.''

The Corvette Z06 E85 concept pace car is based on the production Z06 – already one of the fastest and most powerful cars on the market – and blends its performance with the high-octane, renewable alternative fuel that is derived from a variety of crops grown across the United States.

E85 is blend of 85 percent ethanol and 15 percent gasoline. Its benefits include reduced emissions of greenhouse gases and a reduced dependence on petroleum. GM is the leader in E85 production models, with more than 2.5 million E85-capable cars, trucks and SUVs on the road – with more on the way. Chevrolet offers seven E85-capable models in 2008.

Apart from the fuel system and powertrain controller revisions required to run E85, the Z06 concept pace car is mechanically stock. It is distinguished by a unique Gold Rush Green color-shifting paint scheme that changes between hues of green and gold when viewed from different angles and in different light. A subtle checkered flag pattern also is part of the paint scheme. Safety equipment and strobe lights are the only other equipment added to the car.
