Chevrolet Corvette C5-R
The 2001 Chevrolet Corvette C5-R was a racecar built by Pratt & Miller for GM Racing. It was based on the C5 road car but had a longer wheelbase, wider track, an enlarged 7.0 L V8 and different bodywork with exposed headlamps. It is raced in the American Le Mans Series in the GTS Class and has been to four 24 Hours of Le Mans races.
The car's remarkable 2001 racing season produced eight victories in ten races, including an overall win in the 24 Hours of Daytona and a one-two finish in the GTS class at Le Mans.
In 2002 the C5-R repeated its one-two victory at Le Mans and also dominated the GTS class in the American Le Mans Series. A new transaxle unit replaced the previous year's separate transmission and differential. Corvette faced stiff competition from the new Prodrive Ferrari 550 which led a good number of laps but had problems late leaving the victory to Corvette.
In 2003, the Automobile Club de l'Ouest placed additional restrictions on all 24 Hours of Le Mans competitors, reducing power by 10% in an attempt to slow the cars. At the 2003 season-opening 12 Hours of Sebring race, the C5-Rs remained in winning form, with one of them finishing first in class and eighth overall. Also in 2003 the yellow paint was dropped in favor of a special red, white, and blue color scheme to commemorate the Corvette's 50th anniversary. However, at Le Mans the Prodrive Ferraris spoiled the anniversary and hopes for a three-in-a-row victory in the GTS class.
