context_page_description: The 2011 British Grand Prix was a Formula One motor race held on 10 July 2011 at the Silverstone Circuit in Northamptonshire and Buckinghamshire, England, and won by Fernando Alonso.
  Changes to the circuit mean that the race was previously classified as being in Northamptonshire, but the movement of the start-finish line means that the race is now officially classed as being in Buckinghamshire. It was the ninth race of the 2011 season, and saw the introduction of a ban on off-throttle blown diffusers, the practice of forcing the engine to continue to produce exhaust gasses to generate downforce when drivers are not using the throttle.
