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]
