Overview

• FIA and power-unit manufacturers will meet in London on Sept. 11 to chart the regulations for the era following the 2026 engines.
• FIA president Mohammed bin Sulayem says a V8 direction is decided with an earliest target of 2029, while many manufacturers prefer 2030–2031 to protect recent investments.
• Two concepts are in play: a 2.4-liter naturally aspirated V8 backed by Mercedes, Ferrari, RB Powertrains and Cadillac, and a biturbo V8 favored by Audi.
• There is emerging alignment on the electric side with a battery around 240 kW, roughly 120 kW in normal deployment and up to about 220 kW for overtaking, and the FIA could raise the per‑race fuel limit to near 120 kg if a naturally aspirated route is chosen.
• Costs and fuel pricing are pivotal topics, with the FIA proposing a 20% cut to the 2026 cost cap as teams flag expensive sustainable fuel and manufacturers signal pressure to increase customer-engine fees.
