Mercedes' Formula One car, the Mercedes F1 W05 Hybrid (with drivers Lewis Hamilton and Nico Rosberg) began one of the more dominant periods by a constructor in the sport's history. The "Silver Arrows" won (and led every lap of) the first seven races of the 2014 season, only falling due to a KERS failure on both cars in the 2014 Canadian Grand Prix. Overall, the cars achieved 18 pole positions, 16 wins and eleven 1-2 finishes in the 19-race season. Mercedes won the 2014 Formula One Constructors' Championship (their first) while Hamilton won the 2014 Drivers' Championship.
