2011 Superleague Formula season

The 2011 Superleague Formula season was the fourth and final season Superleague Formula championship. The series reverted to being known simply as "Superleague Formula", with 2009's two-year sponsorship deal with Sonangol also having expired.^[1] The first race of the season was held on 5 June at Assen and was due to finish at a venue in New Zealand after 8 race weekends.

After three seasons in which the cars were run in club team colours, the 2011 season saw drivers competing in the colours of their nation,^[2] with countries adorning team names as had been set out by Team China in 2010, thus beginning a severing of the strong links the series had attempted to make by linking each team entry with a football club. As many as eight of the announced fourteen entries no longer had links with football teams.

The season ended after just two of the scheduled rounds after a number of complications, which saw tracks not being ready in time for the series,^[3] and disagreements with race organisers.^[4]
