2010 NASCAR Sprint Cup Series (Start Your Engines!)

The 2010 NASCAR Sprint Cup Series was the 62nd season of professional stock car racing in the United States and the 39th modern-era Cup series season.

Technical changes
The only change to the cars from 2009 to 2010 was Chevrolet dropping the "SS" moniker from the Impala.

Rule changes
It was announced in January as part of the annual preseason media tour in Charlotte that, after years of restrictions, drivers would be let loose as it were, popularly referred to as "Boys, Have At It". Rules were altered to allow for "bump drafting", especially at Daytona and Talladega. Starting with the Shelby American, NASCAR extended its post-race inspections to include the first car out of the race that was not involved in a wreck; in other words, the first start and park.
