2018 Super GT Series

The 2018 Autobacs Super GT Series was the twenty-sixth season of the Japan Automobile Federation Super GT Championship including the All Japan Grand Touring Car Championship (JGTC) era and the fourteenth season the series has competed under the Super GT name.

The season began on April 8 and ended on November 11, after 8 races.

In the GT500 class, Team Kunimitsu won their first-ever championship with the all-star lineup of series veteran Naoki Yamamoto and 2009 Formula One champion Jenson Button, narrowly beating defending champions Ryō Hirakawa and Nick Cassidy at the final race in Motegi to clinch the title after both teams came in to the race tied in points.

55 ARTA team, despite winning two races in the season, were ultimately too inconsistent in their championship challenge, as two races without scoring a point coupled with poor performance in both Sugo and Motegi ultimately cost them the championship over the more consistent LEON AMG.

31 Toyota Prius apr GT of Koki Saga and Kohei Hirate would finish third, just one point behind the ARTA BMW, while defending champions Goodsmile Racing finished fourth after a poor start to the season and a tire issue in Autopolis ultimately cost them the chance to defend the title.
