Overview

• Engine makers and teams will meet in London on September 11 to discuss the next power unit formula and timelines.
• The leading concept is a 2.4-litre V8 running on fully sustainable fuel with a simplified KERS, cutting the electric share to about 10% from roughly 50% in 2026.
• Proponents claim the proposal could reduce power unit costs by up to around 65% and trim car weight by an estimated 80kg compared with the 2026 generation.
• FIA president Mohammed Ben Sulayem favors an earlier change, potentially in 2029, but several manufacturers argue for 2030 or 2031, with Audi among those wary of an accelerated pivot.
• Separately, F1 CEO Stefano Domenicali is driving a plain-language effort to explain the complex 2026 technical changes to help newer fans understand the sport.
