The 2015 Red Bull Air Race World Championship was the tenth Red Bull Air Race World Championship series, contested over eight events in seven countries held between February and October.
British pilot Paul Bonhomme won his third world title by five points, after winning half of the eight races. His closest challenger was Australian pilot Matt Hall, and the pair finished well clear at the top of the championship. Bonhomme won the opening two races of the season in Abu Dhabi and Chiba, before an eighth-place finish – his worst result of the season – in Rovinj, saw Hall tie his points tally with three podium finishes. After Austria's Hannes Arch won in Rovinj and Budapest, Bonhomme and Hall shared the remaining victories between them; Bonhomme won at Ascot and Fort Worth, while Hall took his first Air Race victories at the Red Bull Ring and Las Vegas Motor Speedway. Arch completed the championship podium, some 42 points in arrears of Bonhomme.
The series also maintained the Challenger Cup format that was introduced for the 2014 season, for young pilots to develop their skills. Each pilot entered at least five races in order to accrue points towards the Cup rankings, with the top six pilots after the Fort Worth event being invited to a winner-takes-all event at Las Vegas Motor Speedway. Mikaël Brageot of France – who had topped the Cup rankings – won the race by 0.035 seconds over Peter Podlunšek, to take the title.
The eight-event calendar for the 2015 season was announced on 25 November 2014. An updated race calendar was released on 3 March 2015, which dropped the round in Sochi, Russia and the round in Rovinj, Croatia returned to the calendar.
As in 2014, Challenger Class pilots had to compete in at least three races throughout the season, with each pilot's best three scores counting towards the Challenger Cup ranking. The top six pilots in the ranking qualified for a winner-takes-all race at the end of the season.
At the last race of the season at Las Vegas, the top six pilots in the standings took part in a race to determine the final ranking of the Challenger Cup.
