(About winning a championship for Team Penske in his first year with the team): I certainly dreamed I could come in and win a lot of races and win the championship. But I don’t think I believed that (a championship) was going to happen. It was certainly hard to believe that.
Roger Penske has been racing and winning in the United States since 1958 and has scored victories in every series in which he has competed.
Penske was one of America's most successful young road racers before he retired from driving in 1965 to focus on his business interests. He fielded Corvettes in the 1966 endurance races at Daytona and Sebring before joining forces with driver Mark Donohue to race in the USRRC and Can-Am sports car series. Penske Racing found success early with Donohue, winning two consecutive USRRC championships and three SCCA Trans-Am championships.
Penske Racing and Donohue moved into Indy car racing by racing in two USAC-sanctioned road races in 1968. In 1969, the team entered the Indianapolis 500 for the first time, and Donohue finished seventh, earning Rookie of the Year honors.
Since then, a Penske Racing car has been in Victory Circle at the Indianapolis Motor Speedway 15 times -- most recently in 2009 with Helio Castroneves -- and won the Verizon IndyCar Series championship in 2006 with Sam Hornish Jr. and 2014 with Will Power.
Drivers who have competed in Penske Racing cars in CART and the Verizon IndyCar Series include Mario Andretti, Al Unser, Bobby Unser, Al Unser Jr., Tom Sneva, Rick Mears, Danny Sullivan, Emerson Fittipaldi, Paul Tracy, Al Unser Jr., Gil de Ferran, Gary Bettenhausen, Paul Tracy, Andre Ribiero, Ryan Briscoe, Juan Pablo Montoya and Simon Pagenaud.
