Formula 3 is one of the classes of open-wheel formula racing also sanctioned by the FIA and comprises various championships held in Europe, Australia, South America and Asia. The F3 series acts as a feeder series for more senior formulas such as the GP2 series and even Formula 1. Some of the youngest and most talented drivers aged as low as 16 years of age transform from racing amateurs and enthusiasts and begin a professional racing career on this series. Formula three cars are also purpose-built, and currently, Dallara (which also manufactures cars for the GP2 and GP3 series) manufactures a majority of F3 cars.

The F3 boasts producing some of the best F1 race drivers such as Michael Schumacher who holds the record for most championships with seven, as well as the race wins and pole position records. The British F3 has also supplied many F1 drivers, with champions including Nigel Mansell, Ayrton Senna and Mika Häkkinen having moved straight from that series to Formula One.

Formula 3 is not a world championship but rather, encompasses several national events and special races that give fans in locations not visited by other major series a way to experience major international racing. Some of the current F3 national championships are: the FIA European Formula Three Championship, All-Japan Formula Three Championship, Euroformula Open Championship, Australian Formula 3, Formula 3 Brazil and the Motorsport Vision Formula Three Cup.

The Formula 3 2015 season kicked off superbly in April at Valencia and has gone through stages at Silverstone, Hockenheim and Pau. Currently, Italian Antonio Giovinazzi is atop the standings table followed by German Maximilian Gunther and Charles Leclerc trailing in third position. F3 enthusiasts however, are also keeping an eye out for Felix Rosenqvist – last year's Macau victor – and youngster George Russell who may also pull a hat trick.
