2012 Super GT Series

The 2012 Autobacs Super GT Series was the twentieth season of the Japan Automobile Federation Super GT Championship including the All Japan Grand Touring Car Championship (JGTC) era and the eighth season as the Super GT series. It also marked the thirtieth season of a JAF-sanctioned sports car racing championship dating back to the All Japan Sports Prototype Championship. The season began on April 1 and ended on November 18, 2012, after eight championship races and a non-championship race.

Masataka Yanagida and Ronnie Quintarelli of Nissan works team MOLA won their second consecutive GT500 Drivers' and Teams' Championships, and became only the second team and driver combination to win the GT500 championship before the final round of the season. Team Taisan Endless and drivers Kyosuke Mineo and Naoki Yokomizo won the GT300 championships in their new Porsche 911 GT3-R, giving Team Taisan their final Super GT championship.

Regulation changes
From this season, the GT300 class fully incorporated the Group GT3 ruleset and Balance of Performance parameters used by the SRO Motorsports Group. Sixteen GT300 entries that competed in all or most domestic rounds were GT3 vehicles. GT3 vehicles won every championship round, plus both races of the non-championship Fuji Sprint Cup, along with the series championship.

2012 saw the introduction of hybrid powertrain vehicles to the GT300 category. Constructor apr introduced a Toyota Prius JAF-GT300 vehicle powered by a battery-driven hybrid system, and Mugen (M-TEC) followed shortly after by introducing the Honda CR-Z GT300 with a racing hybrid system developed by Zytek. Vehicles from the JAF-GT Category C (vehicles based on modified sports cars with minimal production requirements) and Category D (prototype cars not belonging to other JAF-GT categories) were phased out beginning in 2012. These outgoing vehicles included the Mooncraft Shiden, ASL Garaiya, and Vemac RD320R, which had been mainstays of the series for much of the past decade. On the other hand, JAF-GT Category A and B cars, based on mass production models, were allowed to use traction control beginning in 2012, and were also given concessions such as 14-inch width tyres, paddle sequential shifters, and larger diameter air restrictors.
