The Super Taikyu Organisation (STO) has released the provisional entry list for next weekend’s final round of the 2021 Super Taikyu Series Powered by Hankook, the 2021 Super Taikyu Race at Okayama International Circuit.
This final round will take place over two three-hour races. The Group 2 race will feature the ST-2, ST-3, ST-4, and ST-5 cars, plus the hydrogen engine Toyota Corolla Sport H2 Concept from ROOKIE Racing. Group 1 will feature the GT3 and GT4 cars from the ST-X and ST-Z classes, along with the ST-TCR and ST-1 classes, plus ROOKIE Racing’s non-homologated Toyota GR Supra.
Also on the provisional entry list is a third ST-Q class entry, in the same experimental class as the two ROOKIE Racing cars. No details of this entry have yet been announced – though, if and when details of this new entry materialise, we will update the entry list accordingly.
UPDATE: The new entry is Team NOPRO’s #37 Mazda Demio Diesel Turbo, which has now been converted to run on sustainable biodiesel. The car is entered under the Mazda Spirit Racing banner.
Five ST-X cars are entered. D’station Racing have withdrawn their Aston Martin AMR Vantage GT3, as Satoshi Hoshino and Tomonobu Fujii will be under quarantine after returning from Bahrain. However, they’ve already clinched the ST-X Championship at Suzuka in the last round. MP (Magic Project) Racing return with their #9 Nissan GT-R, after voluntarily skipping Suzuka.
The championship in ST-Z is still up for grabs. 13 cars are entered, including two returning entries: Techno First Racing Team are back with their #34 Ginetta G55 GT4, for the first time since the second round at Sugo. And Birth Racing Project have brought back the Porsche Cayman GT4 Clubsport MR that they competed with last season, for a one-off entry. Another one-off Group 1 entry is the #33 Audi Driving Experience Japan RS3 TCR, which is prepared by Hitotsuyama Racing.
New entries in Group 2 include Endless Sports’ new #13 Toyota GR Yaris, which will be driven by Ryo Ogawa and Masayo Hanazato in the ST-2 class; and Techno First have brought back their 2019 ST-3 Championship-winning #34 Lexus RC 350 for this finale. Hiroshima Toyopet Racing have also brought back their #110 Toyota Vitz in the ST-5 class, and Team Yamato are back for the first time since the Fuji 24 Hours with their #67 Honda Fit RS.
Asano Racing Service (ST-4) and Murakami Motors (ST-5), who withdrew from Suzuka as a precaution due to surging COVID-19 cases in central Japan, are back for the final round. In total, there are 56 cars, the largest entry list of the season.
Along with the ST-Z title, both the ST-4 and ST-5 championships will be decided in the last round of the season.
