are less well-known national touring late model series such as the World of Outlaws Late Model Series and regional touring series. Crossover drivers Some drivers have entered stock car racing after starting on a very different career path. The most famous might well be Mario Andretti, who is the only driver ever to win the Indianapolis 500 (1969), NASCAR's Daytona 500 (1967), and the Formula One World Championship (1978). Juan Pablo Montoya is the only other driver with wins in all three series, with two Indy 500 wins (2000 and 2015), seven Formula One wins and two Sprint Cup wins (2007 and 2010). A. J. Foyt, with four Indianapolis 500 wins, seven IndyCar championships, and a victory in the 24 Hours of Le Mans on his resume, also won the Daytona 500 in 1972. Johnny Rutherford, a three-time winner at Indy, has the rare distinction of winning his first NASCAR start, a qualifying race for the 1963 Daytona 500. Dan Gurney, a leading 1960s Formula One driver and later one of the most successful constructors of Indy cars (as well as being Foyt's co-driver at Le Mans), excelled in NASCAR's road-course events, winning at Riverside five times between 1963 and 1968. A notable crossover oddity is the one-race NASCAR career of the colorful Formula One and sports car driver Innes Ireland: after retiring at the end of the 1966 season, he was invited by NASCAR czar Bill France to compete at Daytona, where he was running in the top ten when his engine blew on the 126th of 200 laps. Montoya initially surprised the auto racing community by leaving F1, but he was quickly followed by other drivers. Open wheel stars like Sam Hornish Jr., Patrick Carpentier, Dario Franchitti, Jacques Villeneuve, A. J. Allmendinger and Danica Patrick all made the move to the Monster Energy Cup series, with varying degrees of success. Two-time Australian Supercars champion Marcos Ambrose competed in the Monster Energy Cup Series from 2007 to 2014, winning two races. Other drivers compete often in stock car racing but are well known for their success elsewhere. Ron Fellows and Boris Said are champion road racers and are often brought in by teams solely to compete in NASCAR's road course events, a title known as road course ringers. Robby Gordon was one of NASCAR's few remaining owner-drivers, but he is most famous for his numerous off-road championships and his
