The British driver will make his first outing since he lost his Nissan SUPER GT drive at the end of 2020 with Helm Motorsports for the blue riband round of Japan’s second-tier Super Taikyu series on 27-28 May.
Mardenborough joins team founders and brothers Yuya and Reiji Hiraki, as well as gentleman racer Yutaka Toriba, as the fourth driver at the wheel of Helm’s #1 Nissan GT-R NISMO GT3 as the team seeks to defend its 2022 victory.
The announcement follows the release of the trailer for the forthcoming Gran Turismo movie, the plot of which is based on Mardenborough’s rise to stardom via the Nissan GT Academy competition in 2011.
The 31-year-old spent most of last year lending his assistance to the production of the film, which is due for release in August, while working on his own racing comeback and undertaking Formula E simulator duties.
“I am honoured and excited to join Helm Motorsports for the Super Taikyu Fuji 24 Hours,” said Mardenborough. “I want to thank Yuya and Reiji Hiraki for this opportunity and I look forward to working with the team to achieve great results.
“It has been an incredible journey so far, and I also hope that my story being brought to life on the big screen with the Gran Turismo movie will inspire others to chase their dreams.”
Mardenborough has been openly targeting a return to the Japanese scene, where he spent five seasons as part of his decade-long association with Nissan.
He initially combined Japanese Formula 3 and a campaign in SUPER GT’s lower GT300 class before stepping up to the marque’s GT500 stable for 2017 with Team Impul, with which he also contested a season of Super Formula that year.
In 2019 he switched to Kondo Racing before being dropped for 2021 to make way for Nissan to sign Nobuharu Matsushita.
