Buick Enclave

The Buick Enclave is a full-size luxury crossover SUV launched in May 2007 as a 2008 model by Buick. The Buick Enclave, GMC Acadia, and Chevrolet Traverse all share the GM Lambda platform. The Enclave was previewed at the 2006 North American International Auto Show, officially as a concept car, making it the first Lambda vehicle to be displayed.

The Enclave is partially based on the Buick Centieme concept shown at the 2003 Detroit Auto Show.

The event, billed as The Greatest Spectacle in Racing, is considered part of the Triple Crown of Motorsport, which comprises three of the most prestigious motorsports events in the world. The official attendance is not disclosed by Speedway management, but the permanent seating capacity is upwards of 250,000, and infield patrons raise the race-day attendance to approximately 300,000.

The inaugural running was won by Ray Harroun in 1911. The race celebrated its 100th anniversary in 2011, and the 100th running will be held in 2016. Juan Pablo Montoya is the defending champion. The most successful drivers are A. J. Foyt, Al Unser, and Rick Mears, each of whom have won the race four times.

Rick Mears holds the record for most career pole positions with six. The most successful car owner is Roger Penske, owner of Team Penske, which has 16 total wins and 17 poles.

Two drivers, both of whom are multiple winners, have their respective names depicted differently in different years. Four-time winner Al Unser, Sr. has his name listed as "Al Unser" for his likenesses of 1970, 1971, and 1978. He is listed as "Al Unser Sr." for his 1987 win, owing much to the fact that his son (two-time winner Al Unser, Jr.) was now a driver. Two-time winner Juan Pablo Montoya is listed as "Juan Montoya" for 2000 and as "Juan Pablo Montoya" for 2015.
