Vettel used the RB7 to claim the 2011 World Drivers' Championship in Japan and Red Bull won the World Constructors' Championship the following weekend in South Korea. The car achieved three 1-2 finishes during the season. It is one of the most dominant Formula One cars ever built, winning 12 of the 19 races and claiming all but one pole position in the 2011 season, in part due to the innovative but controversial exhaust-blown diffuser.
