Upcoming Autopolis GT 3 Hour Race: Championship Deciders Loom
As the 2025 Autobacs SUPER GT Series approaches its penultimate race at the Autopolis International Racing Course on October 19, the stakes are particularly high with championship titles on the line in both GT500 and GT300 categories. A total of 42 cars are slated to compete, with 15 entries in GT500 and 27 in GT300.
Key Insights Ahead of the Race
Success Weight Adjustments: For this race, teams will carry Success Weight of one kilogram per championship point scored, with only the leading #1 au TOM’S Toyota GR Supra (Sho Tsuboi and Kenta Yamashita) and the #14 Eneos X Prime GR Supra (Kazuya Oshima and Nirei Fukuzumi) subject to the ‘Stage 1’ fuel flow restrictor.
Historical Context: Tsuboi has been particularly strong in penultimate races, having secured victories in both of the previous seasons at Autopolis and Motegi. Last year, TGR Team SARD will defend its title at Autopolis after finishing second in their most recent race at Sportsland Sugo.
Recent Form: Toyota dominated the early season with a record nine consecutive victories, yet Nissan has surged recently, clinching the last two wins. In contrast, Honda seeks to avoid a winless season as they face their final two races.
Strategic Driver Entries: Notably, the #19 WedsSport Advan GR Supra will feature a third driver, Kazuto Kotaka, returning after varied commitments this season across Super Formula and GT World Challenge.
GT300 Dynamics: The GT300 field will see a notable absence due to damage sustained by SHADE Racing’s #20 Toyota GR86, sidelining them for the second time this season.
Notable Driver Line-ups
