2025 Super GT Series

The 2025 Autobacs Super GT Series is a planned motor racing championship based in Japan for grand touring cars. The series is sanctioned by the Japan Automobile Federation (JAF) and run by the GT Association (GTA). It will be the thirty-third season of the JAF Super GT Championship, which includes the All Japan Grand Touring Car Championship era, and the twenty-first season under the Super GT name. It will be also the forty-third overall season of a national JAF sportscar championship dating back to the All Japan Endurance/Sports Prototype Championship.
TGR Team au TOM'S of Sho Tsuboi and Kenta Yamashita entered the season as the defending champions of the GT500 class. And JLOC Takashi Kogure and Yuya Motojima entered the season as the defending champions of the GT300 class.
The provisional calendar for 2025 was confirmed on 1 August 2024, which consists of eight races. The series will race abroad for the first time since 2019, and they will return to race at Sepang International Circuit for the first time since 2013.
The GTA confirmed several changes for the 2025 Super GT season.
After a year of using the aggregate qualifying format, the qualifying system will revert back to the knockout format. For GT500 qualifying, 10 cars will advance to Q2 instead of 8 which previously held before. And for the GT300, 9 cars will advance to Q2 from 2 groups of 14 cars. The qualifying points of rewarding top 3 cars will be scrapped, and revert back to awarding a single point for pole position in both classes.
There will be changes in the GT300 drivers' and teams’ championship points, classified top 15 finishers will be able to collect points up from 10 finishers. The winner will be awarded 25 points while 2nd place will receive 20 points. 3rd place will revive 16 points, then 4th and 5th will get 13 and 11 points respectively, and from 6th to 15th, 10 points down to 1 point will be awarded. Also, races over 700km in length or four hours in duration no longer have a fixed points system, instead this will be announced by the series in advance of each round.
Teams are allowed to bring in 4 sets of dry and 6 sets of wet tyres for the 300km races. New: One wet tyre set must be functioning in heavy rain conditions. From Round 2 onward, GT500 tyre manufacturers who haven't won a race in 2024 may bring in one extra dry set.
During the formation lap, the distance to the car in front should be within 5 car lengths to avoid a spread out start. To avoid slow driving to save fuel when driving to the grid, a speed minimum of 80 km/h or more has to be maintained. Infractions will see a time penalty applied, along with the previous grid penalty and drive-through penalty.
To comply with a new FIA standard, carbon helmets will be mandatory from this season onward with satisfactory helmets given GTA stickers. However, there will be a grace period for drivers who can't obtain one for the opening race.
The series also announced a revision to the system of handicaps for the GT300 class, introducing the modification of refueling times as a form of success penalty. The nominal limit returns to 100 kg where previously was 80 kg, but the actual weight loaded not exceed 50 kg, and with the adjustment of refueling times added as a secondary measure to further penalize the most successful cars. This will be achieved by way of a GTA-supplied restrictor to be attached to the refueling rig, the diameter of which will be announced by bulletin prior to each race. Success ballast will continue to be accrued at the rate of 2 kg per point, with the handicap halved for the penultimate round at Autopolis and eliminated for the Motegi finale.
