Daniel Sexton Gurney was an American racing driver, race car constructor, and team owner who reached racing's highest levels starting in 1958. Gurney won races in the Formula One, Indy Car, NASCAR, Can-Am, and Trans-Am Series. Gurney is the first of three drivers to have won races in sports cars (1958), Formula One (1962), NASCAR (1963), and Indy cars (1967), the other two being Mario Andretti and Juan Pablo Montoya.

American open-wheel car racing, generally known as Indy car racing, or more formally Indianapolis car racing, is a category of professional automobile racing in the United States. As of 2024, the top-level American open-wheel racing championship is sanctioned by IndyCar. Competitive events for professional-level, open-wheel race cars have been conducted under the auspices of various sanctioning bodies, tracing its roots as far back as 1902. A season-long, points-based, National Championship of drivers has been officially recognized in 1905, 1916, and each year since 1920. As such, for many years, the category of racing was known as Championship car racing. That name has fallen from use, and the term Indy car racing has become the preferred moniker.
