Sho Tsuboi Poised for F2 Move as Zak O'Sullivan Switches to Formula E

Sho Tsuboi, a Toyota-backed driver and the 2024 Super Formula champion for TOM'S, is set to leave the series at the end of the season to switch to FIA Formula 2. The 31-year-old is currently involved in Haas F1 team's Testing of Previous Cars (TPC) programme, which shares a technical partnership with Toyota. He recently participated in a TPC test at Jerez alongside Haas reserve drivers Ryo Hirakawa and Jack Doohan.

Kazuki Nakajima, vice-chairman of Toyota Racing, stated that the company is ready to support its drivers' ambitions if they wish to compete internationally. As Tsuboi prepares for his move to F2, Ritomo Miyata, who currently drives for Hitech in F2, looks unlikely to remain in the category for another year. Miyata could potentially return to Japan to reunite with TOM'S in both Super Formula and Super GT.

In another development, Zak O'Sullivan will depart Super Formula to join Envision Racing in Formula E for the 2026/27 season. The former Williams F1 reserve driver will race alongside Maximilian Gunther in Envision's new lineup. However, a schedule overlap between Formula E's pre-season test at Jarama on 16–20 November and the Super Formula finale at Suzuka on 20–22 November leaves it uncertain whether O'Sullivan will complete the current Super Formula season.
