One of America's greatest racing drivers, Mario Andretti has virtually won it all, the Indianapolis 500, the Daytona 500, the International Race of Champions (IROC) series, CART, and Formula 1 World titles. Andretti was born in Montona, Italy (now Motvun, Croatia) and with his family, including twin brother Aldo, moved to the United States in 1955. Ever since he was a little boy, his goal was to win the world championship and he accomplished this in 1978 as America's second and last world champion (he was naturalized when he was in his teens). He later won the CART title (America's top open-wheel series) and retired from racing in 1995. His son Michael is also a CART champion and went on to become a successful team owner. Andretti is still enormously popular with race fans and is one of the most recognized personalities in the sport.
