The 2011 NASCAR Sprint Cup Series season was the 63rd season of professional stock car racing in the United States. The season included 36 races and two exhibition races, beginning with the Daytona 500 at Daytona International Speedway and ending with the Ford 400 at Homestead-Miami Speedway. The final ten races were known as 2011 Chase for the Sprint Cup.
During the 2010 season, NASCAR announced several calendar changes, including race additions at Kansas Speedway and Kentucky Speedway, and the removal of one race each from Atlanta Motor Speedway and Auto Club Speedway. Once the 2010 season had concluded, NASCAR also announced changes to the point system, and that the fuel changed from Sunoco unleaded to an ethanol blend called 'Sunoco Green E15'.
Margaret Haas won the Owners' Championship, while Tony Stewart, co-owner of Stewart-Haas Racing with Gene and Margaret, won the Drivers' Championship with a victory at the final race of the season in a tiebreak over Carl Edwards. Chevrolet won the Manufacturers' Championship with 248 points. Taken from http://en.wikipedia.org/wiki/2011_NASCAR_Sprint_Cup_Series.
