- Tsuboi won 2024 Super Formula title with TOM’S team
- He participated in Haas F1 Testing of Previous Cars programme

Toyota-backed Sho Tsuboi will exit Super Formula after 2026 and step into FIA Formula 2 in 2027, pursuing a broader international platform after his 2024 title with TOM’S.
He tests with Haas under the Testing of Previous Cars programme, including Jerez in September alongside Ryo Hirakawa and Jack Doohan, his third 2026 outing and fifth since July 2025.
Haas’s technical alliance with Toyota strengthens the link between his F2 step and any F1 prospects, while Ayao Komatsu’s driver choices shape the team’s medium‑term pathway.
Haas’s technical alliance with Toyota underpins Tsuboi’s most credible F1‑relevant pathway yet.
F2 offers European mileage, varied circuits, and relevant tyre management, giving Tsuboi a sharper reference against peers on identical machinery and a clearer benchmark for potential F1 evaluators.
He mirrors Ritomo Miyata’s route from Super Formula to F2, though Miyata’s next step remains unsettled after a breakthrough Hitech season alongside Colton Herta and a maiden victory at Madras.
Tsuboi leaves Super Formula after 2026 to debut in FIA Formula 2 in 2027.
Toyota Racing vice‑chairman Kazuki Nakajima indicates support for Tsuboi’s international ambitions without revealing concrete plans, emphasising flexibility as Toyota-backed drivers pursue opportunities created by the Haas link.
Elsewhere, Zak O’Sullivan departs Super Formula to join Envision Racing in Formula E for 2026/27, after two seasons as Envision’s simulator and reserve while helping revive Team Impul’s form.
Pre‑season testing at Jarama runs November 16‑20 and clashes with Suzuka’s November 20‑22 finale, so O’Sullivan may leave testing early. Team director Kazuki Hoshino declines comment on arrangements.
Formula E testing at Jarama overlaps Suzuka’s Super Formula finale, creating a tight logistical call for O’Sullivan.
Tsuboi’s exit forces TOM’S and Toyota to reshape line‑ups across Super Formula and Super GT, aligning with Toyota’s broader replacement planning as programmes evolve for 2027.
The 2027 F2 campaign is the critical audit of Tsuboi’s ceiling, set against Europe’s best and venues like the Baku City Circuit, while Haas mileage keeps F1 conversations active.
