Mateschitz's brands are consistently marketed as associated with the physical and mental attributes needed for various types of extreme sports through commercial sponsorship. Red Bull formerly owned more than 60 percent of the Sauber Formula One motor racing team, and was the team's main sponsor. However, Red Bull ended its relationship with Sauber at the end of 2001 after the team opted to sign Kimi Räikkönen as one of their drivers for the 2001 season instead of Red Bull protege Enrique Bernoldi. In November 2004, Mateschitz bought the Jaguar Racing Formula One team from its previous owners, Ford, and renamed it Red Bull Racing. In September 2005, Mateschitz joined forces with his close friend and former Formula One driver, Gerhard Berger, to purchase the Italian-registered Minardi team from its Australian owner Paul Stoddart. The team was renamed "Scuderia Toro Rosso", "Toro Rosso" meaning Red Bull in Italian. In 2010, Red Bull Racing won the Formula One World Constructors' Championship and Drivers' Championship with Sebastian Vettel. They then went on to win both titles for the next three years running in 2011, 2012, and 2013, making Vettel and Red Bull Racing four-time world champions.
