2015 Formula One World Championship

The 2015 FIA Formula One World Championship was a motor racing championship for Formula One cars. It was the 66th Formula One World Championship recognised by the sport's governing body, the Fédération Internationale de l'Automobile (FIA), as the highest class of competition for open-wheel racing cars. Twenty-two drivers representing 10 teams contested 19 Grands Prix, starting in Australia on 15 March and ending in Abu Dhabi on 29 November as they competed for the World Drivers' and World Constructors' championships.

Lewis Hamilton was the defending Drivers' Champion after securing his second title at the 2014 Abu Dhabi Grand Prix. His team, Mercedes, began the season as the defending Constructors' Champion, having clinched its first championship title at the 2014 Russian Grand Prix.

The calendar featured two significant changes from the 2014 season. The first was the return of the Mexican Grand Prix, held for the first time since 1992. The other change was the cancellation of the German Grand Prix after a venue could not be agreed upon, leaving the nation without a World Championship event for the first time in fifty-five years.

Hamilton secured his third Drivers' Championship with three races left in the season. The runner-up was his teammate Nico Rosberg, 59 points behind, with Ferrari's Sebastian Vettel third, another 44 points adrift. Mercedes AMG Petronas F1 Team clinched the 2015 Constructors' Championship^[2] at the Russian Grand Prix, ahead of Ferrari and Williams, and ended the season with a record 703 points. Hamilton also won the FIA Pole Trophy with a total of 11 pole positions in the season and the DHL Fastest Lap Award. Ferrari won the inaugural DHL Fastest Pit Stop Award.
