In the United States, the 1928 AAA Championship featured seven major races, including the Indianapolis 500, with Louis Meyer winning both the Indy 500 and the national title. Board tracks, dirt ovals, and regional events remained popular, with drivers like Ray Keech, Cliff Woodbury, and Leon Duray also claiming victories in other championship races.
Internationally, European Grand Prix racing had no formal championship because several planned races were canceled and there were too few events with consistent rules to award an official title. Bugatti dominated many events, with drivers like Louis Chiron and Tazio Nuvolari achieving notable wins. Endurance events such as the 24 Hours of Le Mans saw Bentley secure victory, while races like the Targa Florio and the first Australian Grand Prix expanded the global scene. The year was marked by evolving technical regulations and tragic accidents, including a deadly crash at Monza, underscoring both the excitement and risks of the era.
