It was set to be the final round of the 2008-09 A1 Grand Prix season, but became the season finale, due to the cancellation of the Mexican round due to the 2009 swine flu pandemic.

A1 Team Ireland became the fourth A1 Grand Prix champions, with a double pole position, and double victory, to take Ireland's first international motor racing championship.

With the British round now becoming the season finale, this left the championship in a three-way battle for the title.

Also, even if all the teams finish equal of points, the tie-breaker rules would come into play.

† Team utilized Powerboost "joker" qualifying lap.
