Super Formula Considers Extending Lifespan of Current Dallara Car Beyond 2027

Super Formula may keep its Dallara SF23 chassis beyond 2027, with JRP president Yoshihisa Ueno confirming the next-generation project remains exploratory.

The SF23 was slated for replacement from 2028, but Ueno says no final decision is made. The concept phase continues before any technical tender or timeline is set.

Targets span speed, raceability, aesthetics, and engine sound, with strict cost discipline. The remit is to meet fan expectations without overloading teams financially or operationally.

Stakeholder consultations are ongoing across teams, suppliers, and promoters. That feedback will determine the car’s direction and whether incremental evolution or a clean-sheet design is justified.

Dallara has supplied chassis since 2014, yet Ueno leaves alternatives open. Market competitiveness, support capability, and lifecycle cost will decide any supplier change.

International expansion is paused. A planned 2025 round at Inje Speedium collapsed after agreement failed, and the 2026 calendar carries no overseas events.

Calendar changes continue domestically. The 2026 season opener moves from Suzuka to Motegi, prompted by Formula 1’s Suzuka date shift that compresses preparation time.

Motegi returns for the first time since 2020, with Suzuka targeted to resume opening duties in 2027. Talks to run as an F1 support event ended without agreement.

Extending SF23 would safeguard cost control and continuity, aiding privateer stability. The trade-off is delayed innovation, so performance uplift targets must be realistic and measurable.

Technical choices will focus on downforce levels, wake management, and tyre operating windows. Engine sound remains a priority for spectacle without undermining efficiency targets.

Any supplier switch requires early definition of spares, testing, and upgrade cycles. Teams need clear homologation rules to plan staffing, simulator work, and inventory.

Expect greater clarity in the coming months as 2028 approaches. Super Formula’s strategy favors measured progress over headline changes, with fan appeal and sustainability as equal pillars.
