Overview

• Formula 1 and the FIA have called manufacturers and teams to a September 11 meeting after Monza to discuss the next power unit cycle beyond 2026.
• The leading concept under review is a 2.4‑litre V8 using fully sustainable fuel with a simplified KERS, targeting roughly a 10% electrical contribution.
• Proponents cite major savings and weight cuts, with reports indicating potential cost reductions of up to about 65% and power units around 80kg lighter than 2026 designs.
• Timing remains contested, with an earlier 2029 shift floated while many manufacturers prefer 2030 to preserve a five‑year cycle and align with new chassis rules.
• Separately, Stefano Domenicali says F1 will explain the 2026 overhaul in plain language, as next year’s cars shrink, adopt active aero, move to near 50/50 ICE‑electric output, and use an overboost in place of DRS.
