Team Penske joined the IndyCar circuit in 1968 with driver Mark Donahue, who won the team's first race at Indianapolis in 1972. By the late 1980s, the team had become one of the highest rated in IndyCar, and hired drivers like Emerson Fittipaldi, Rick Mears, and Al Unser Jr. to name three. In the early 1990s, Penske won many races and has continued to be a force in the series ever since. In 2003, they switched to the Indy Racing League, now known as the IndyCar Series, and hired Sam Hornish Jr. and Gil de Ferran to drive. Both won championships. Even though Penske has not won a championship since 2006, the team is always one of the fastest in the series. In 2014, their drivers will be Juan Pablo Montoya who left NASCAR to move to open wheel racing, three time Indy 500 winner Hélio Castroneves, and top ranked Australian driver Will Power. The team's headquarters are in Mooresville, North Carolina.
