Kimi Antonelli faces the greatest risk of a power-unit grid penalty.

Antonelli has reached his season allocation for the internal combustion engine, exhaust, energy store and control electronics. Using another of any of those components would bring a 10-place grid penalty.

Isack Hadjar, Lando Norris, Lance Stroll, Fernando Alonso and Carlos Sainz have already served power-unit penalties this season. Further allocation breaches would cost them five grid places per component.
