F1 announces changes to 2026 rules and plans for 2027 adjustments

Summary

Formula 1 is revising its regulations after only half a season under the 2026 rules. The FIA's World Motor Sport Council has approved a two-stage overhaul that will affect 2027 and 2028, responding to issues like cars losing electrical power mid-straight. Key changes include altering the combustion-to-electrical power ratio and increasing the internal combustion engine's power cap. Adjustments to aerodynamic features are also set, while challenges remain due to fuel capacity limits that necessitate shorter race distances. Additional pre-season testing is scheduled ahead of 2027 to accommodate increased technical complexity.
