GTA chairman Masaaki Bandoh revealed the plans in his regular press conference ahead of this weekend's season finale at Motegi on Saturday. SUPER GT brought in a new 450km race format last year, with one race each at Fuji and Suzuka being run to the longer distance instead of the regular 300km length. For the 2023 season, 450km became the default distance, with Autopolis using the format for the first time and only the races at Okayama, Sugo and Motegi staying at 300km.
At around 480km, it would be slightly longer than the 450km format, although shorter than the 500km length that used to be a regular feature of the SUPER GT schedule. Fuji and Suzuka appear to be the most likely candidates for the new formats be used, especially with both venues set to again host two races apiece in 2024. Bandoh previously has spoken of making the August Suzuka race a timed event.
