The 2026 Regulations

The 2026 ruleset is the most radical technical reset since the hybrid introduction. Cars are shorter and narrower. Power units split electrical and combustion output roughly 50/50. Active aerodynamics — movable front and rear wings — replace the static downforce maps of the ground-effect era.

Cadillac's arrival as the 11th team ends a decade of grid stability. Sergio Pérez leads the American entry alongside a field reshaped by Audi's takeover of Sauber, new driver line-ups, and a regulatory philosophy aimed at closer racing and lighter machinery.

Whether the reset compresses the field or creates a new dynasty remains the central question of the era's opening seasons. The regulations are designed to reward energy management and adaptability — traits that may favour different teams than the ground-effect formula did.
