Michael Mario Andretti (born October 5, 1962) is an American semi-retired auto racing driver and current team owner. 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. Mario Gabriele Andretti (born February 28, 1940) is an Italian-born American former racing driver. One of the most successful drivers in the history of motorsports, Andretti is one of only two drivers to have won races in Formula One, IndyCar, the World Sportscar Championship, and NASCAR (the other being Dan Gurney). He has also won races in midget car racing and sprint car racing. During his career, Andretti won the 1978 Formula One World Championship, four IndyCar titles (three under USAC sanctioning, and one in CART), and IROC VI. To date, he remains the only driver ever to win the Indianapolis 500 (1969), Daytona 500 (1967) and the Formula One World Championship, and, along with Juan Pablo Montoya, the only driver to have won a race in the NASCAR Cup Series, Formula One, and an Indianapolis 500. As of 2021, Andretti's victory at the 1978 Dutch Grand Prix is the last Formula One win by an American driver. Andretti had 109 career wins on major circuits. Andretti had a long career in motorsports. He was the only person to be named United States Driver of the Year in three decades (1967, 1978, and 1984). He was also one of only three drivers to have won major races on road courses, paved ovals, and dirt tracks in one season, a feat that he accomplished four times.
