The 2026 Super GT Series (known for sponsorship reasons as the 2026 Autobacs Super GT Series) is a planned motor racing championship based in Japan for grand touring cars, which will be the thirty-fourth season of the Super GT series, tracing its lineage to the All Japan Grand Touring Car Championship era. It is the twenty-second season for the series under the Super GT name, and the forty-fourth season of a Japan Automobile Federation (JAF) national sportscar championship, dating back to the All Japan Endurance/Sports Prototype Championship.
TGR Team TOM'S drivers Sho Tsuboi and Kenta Yamashita enter the season as the defending champions of the GT500 class.
The provisional calendar for 2026 was confirmed on 5 August 2025, which consists of eight races. On 9 January 2026, the dates of the Sepang International Circuit round were shifted from 19âÂÂ20 June to 20âÂÂ21 June.
On 19 October 2025, it was announced that the 2026 season would be the last with different tire manufacturers competing against one another. The series will switch to a single tire manufacturer in each class in 2027.
Teams are now only permitted to use one engine per season, and the standard fuel flow rate of GT500 engines has been reduced from 95 kilogrammes per hour to 90.2 kg/h.
GT500 Success Weight has been modified. Once a car accumulates over 50 kilogrammes of Success Weight, the engine fuel flow rate is reduced to 88 kg/h. When that car accumulates more than 67 kg of Success Weight, a "success refuelling restrictor" is installed in to lengthen the refuelling time during pit stops. An even smaller restrictor is installed once the car accumulates more than 84 kg of Success Weight. In addition, none of the original 50 kg of physical ballast weight is removed until the Success Weight is reduced over the final two rounds of the season.
No individual can serve as both an active racing driver and as a team director simultaneously.
