Ocon and Tsunoda withdrew due to violations of the parc ferm rules after qualifying. This brings the total number of drivers that for the US GP undergoes some form of grid penalty on six drivers.
The Alpine F1 team installed Esteban Ocon a sixth internal combustion engine, a fourth energy storage system and a seventh exhaust system after qualifying. According to the sporting regulations, Esteban Ocon must therefore start the race from the pit lane.
Yuki Tsunoda in turn received a fourth gearbox under parc ferm conditions. Only four units may be used during the season, but since it happened under parc ferm conditions, Tsunoda will receive a five-place grid penalty.
