2013 Super Formula Championship

The 2013 Japanese Championship Super Formula season was the forty-first season of premier Japanese open-wheel motor racing, and the first under the new name of Super Formula. The series was contested over six rounds and a non-championship final round at Fuji Speedway as part of the JAF Grand Prix. 2013 was also the last season using the original chassis (SF13, known as FN09 in previous seasons) by Swift Engineering as for 2014 Dallara would supply a new chassis, the SF14, to the series.

Naoki Yamamoto won his first drivers' championship with Team Mugen, while Petronas Team TOM's won the teams' championship. Yamamoto and André Lotterer finished the year with the same number of points. At the time, Super Formula had an unconventional championship tiebreaker method where the driver that scored the most points in the final round of the season would be declared the champion. Lotterer had more wins, but had to miss the final round due to his commitments in the FIA World Endurance Championship, while Yamamoto finished first and third in the double-header finale at Suzuka to equal Lotterer's point total and win the championship.

In the same season, Loïc Duval won the Sportsland Sugo round, defeating Lotterer by 0.041 seconds. It was the closest margin of victory in series history.
