Chevrolet-Corvette

Chevrolet-Corvette

The Chevrolet Corvette is a sports car by the Chevrolet division of General Motors (GM) that has been produced in seven generations. The first model, a convertible, was designed by Harley Earl and introduced at the GM Motorama in 1953 as a concept show car. Myron Scott is credited for naming the car after the type of small, maneuverable warship called a corvette. Originally built in Flint, Michigan and St. Louis, Missouri, the Corvette is currently manufactured in Bowling Green, Kentucky and is the official sports car of the Commonwealth of Kentucky.
A Corvette has been used as the Indianapolis 500 pace car 12 times.
 The first generation Corvette was introduced late in the 1953 model year. Originally designed as a show car for the 1953 Motorama display at the New York Auto Show, it generated enough interest to induce GM to make a production version to sell to the public. To keep costs down, GM executive Robert F. McLean mandated off-the-shelf mechanical components, and used the chassis and suspension from the 1952 Chevy sedan. The drivetrain and passenger compartment were moved rearward to achieve a 53/47 front-to-rear weight distribution. It had a 102-inch wheelbase. The engine was the same inline six that powered all other Chevrolet models, but with a higher-compression ratio, three Carter side-draft carburetors, and a more aggressive cam. Output was 150 horsepower. Because there was currently no manual transmission available to Chevrolet rated to handle 150 HP, a two-speed Powerglide automatic was used. 0-60 mph time was 11.5 seconds. To keep tooling costs in line, the body was made out of fiberglass instead of steel. First production was on June 30, 1953.

The all-new, seventh-generation 2014 Corvette Stingray will serve as the Indianapolis 500 Pace Car, leading the field to green at the start of the 97th running of "The Greatest Spectacle in Racing," on Sunday, May 26, 2013, at Indianapolis Motor Speedway.
It marks a record 12th time the Corvette has served as the Pace Car, starting in 1978.
"It is an honor to help inaugurate the all-new Corvette Stingray at the hallowed Brickyard and further the legacy between Chevrolet and the Indianapolis 500," said Jim Campbell, GM vice president of Performance Vehicles and Motorsports. "The 2014 Corvette Stingray's performance was influenced by racing, making this prestigious assignment even more fitting."
 long with Chevrolet's return in 2012 as an engine supplier, the Corvette Stingray Pace Car extends a legacy at the Brickyard that dates to the racetrack's early days.
"Chevrolet is a great partner of the Speedway," said Jeff Belskus, Indianapolis Motor Speedway Corporation president and chief executive officer. "That connection is heightened this year with the next-generation Corvette in front of a very talented field of racers."
Decked out in Laguna Blue Tintcoat with official Indianapolis 500 graphics on the doors, the Corvette Stingray Pace Car differs from production models with only track-mandated safety features and strobe lights. No powertrain upgrades are required to run in front of the IndyCar pack, thanks to its all-new 6.2L LT1 engine, which features advanced technologies including direct fuel injection, continuously variable valve timing and Active Fuel Management (cylinder deactivation). They help produce an estimated 450 horsepower more efficiently.
