Mario Gabriele Andretti (born February 28, 1940) is an Italian-born American former racing driver, one of the most successful Americans in the history of the sport. He is one of only two drivers to have won races in Formula One, IndyCar, World Sportscar Championship and NASCAR (the other being Dan Gurney). He also won races in midget cars, and sprint cars. During his career, Andretti won the 1978 Formula One World Championship, four IndyCar titles (three under USAC-sanctioning, one under 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. No American has won a Formula One race since Andretti's victory at the 1978 Dutch Grand Prix. Andretti had 109 career wins on major circuits.

John Surtees, CBE (11 February 1934 - 10 March 2017) was an English Grand Prix motorcycle road racer and Formula One driver. He was a four-time 500cc motorcycle World Champion – winning that title in 1956, 1958, 1959 and 1960 – the Formula One World Champion in 1964, and remains the only person to have won World Championships on both two and four wheels. He founded the Surtees Racing Organisation team that competed as a constructor in Formula One, Formula 2 and Formula 5000 from 1970 to 1978. He was also the ambassador of the Racing Steps Foundation.
