The 2015 Formula One World Championship was the 69th season of FIA Formula One motor racing. It featured the 2015 Formula One World Championship as the highest class of competition for open-wheel racing cars. Twenty-two drivers representing ten teams contested nineteen 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. The calendar featured two changes from the 2014 season: the return of the Mexican Grand Prix for the first time since 1992 and the cancellation of the German Grand Prix, leaving Germany without a World Championship event for the first time in fifty- five years. Lewis Hamilton secured his third Drivers' Championship, and the runner-up was his teammate Nico Rosberg, with Ferrari's Sebastian Vettel third. The Mercedes-AMG Petronas F1 Team (car pictured) clinched the Constructors' Championship 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.
