Statistically one of the most successful drivers in the history of American open-wheel car racing, Andretti won the 1991 CART PPG Indy Car World Series and amassed 42 race victories, the most in the CART era and fourth-most all time. Since his retirement from active racing, Andretti has owned Andretti Autosport, which has won four IndyCar Series championships and five Indianapolis 500 races. He is the son of Formula One World Champion and Indianapolis 500 winner Mario Andretti, and the father of current IndyCar Series driver Marco Andretti. Racing career Early career Michael Andretti was born in Bethlehem, Pennsylvania in the Lehigh Valley region of eastern Pennsylvania to race car driver Mario Andretti, a four-time IndyCar champion and one-time Formula One champion, and his wife Dee Ann (née Hoch) Following a successful career racing karts, winning 50 of his 75 races over eight years, Andretti moved into racing cars. He obtained his SCCA National License in 1980, then won six races to claim the SCCA's Northeast Division Formula Ford championship in 1981. He also drove in a number of Formula Vee races in regional SCCA events. In 1982, he won six of the 11 races on his way to winning the Robert Bosch US Formula Super Vee Championship. He also won the opening race of the 1983 Super Vee season before he moved up to drive in Formula Atlantic, and won his second title by winning the FIA Formula Mondial North American Cup the following season. Although he made his international sports car debut at the 1982 24 Hours of Le Mans, he was denied the opportunity to race, as the Mirage M12 he had chosen to race with his father was disqualified 80 minutes before the race was due to start. The father and son partnership returned to the Circuit de la Sarthe the following year, and were joined by Philippe Alliot in the Porsche Kremer Racing's Porsche 956, taking third place. Andretti also raced alongside his father in the Riverside 6 Hours where they were joined by A. J. Foyt and Preston Henn, but the Porsche 935 failed to finish. The father and son duo paired up again the 1984 24 Hours of Daytona, this time in a full-works Porsche 962, which made its race debut. They took pole position,
