2011 Formula One season

The 2011 Formula One season was the 62nd season of FIA Formula One motor racing. The original calendar for the 2011 Formula One World Championship consisted of twenty rounds, including the inaugural running of the Indian Grand Prix before the cancellation of the Bahrain Grand Prix. Pirelli returned to the sport as tyre supplier for all teams, taking over from Bridgestone.Red Bull Racing was the reigning Constructors' Champion. Red Bull Racing's Sebastian Vettel was the defending Drivers' Champion, one of five World Champions appearing on the grid. Vettel won his second World Championship at the 2011 Japanese Grand Prix, becoming the youngest driver, at 24 years and 98 days, to do so. Red Bull Racing won the Constructors' Championship.

After a dispute between the Formula One Teams Association (FOTA) and the FIA in the first half of 2009, a new Concorde Agreement was signed on 1 August 2009 by the then FIA president Max Mosley and all of the existing teams at the time. The new agreement provides for a continuation of the terms of the 1998 agreement, and runs until 31 December 2012. The FIA published a provisional entry list on 30 November 2010, which was revised on 2 December 2010.

Following USF1's inability to make the grid in 2010, the FIA opened a new selection process to find an additional team to occupy the empty slot, as well as possible reserve entrants for the event of other withdrawals. Fifteen entry bids were reported to have been received, including ART Grand Prix, winners of several championships in feeder series; previous 2010 applicants Stefan Grand Prix and World Series by Renault team Epsilon Euskadi; and a joint effort by 1997 World Champion Jacques Villeneuve with Durango, the former Italian GP2 team that had encountered financial difficulties. However, the number of applicants declined, as ART Grand Prix and Cypher, the renamed USF1 operation, withdrew their entries, and the FIA decided ahead of the 2010 Italian Grand Prix that none of the prospective entrants met the minimum funding or engineering requirements, leaving the grid slot vacant.
