Speaking after the session, the champion appeared demoralised as he already seemed resigned to a US Grand Prix loss, and instead looked ahead to Mexico.
However, just hours before the US GP, Russell was placed under investigation by FIA stewards.
According to the FIA, Mercedes did not cover his car two hours after the end of qualifying but continued to work on the car, which is not in compliance with Article 40.6 of the sporting regulations.
The rule states: “whilst cars are covered overnight, they may be fitted with devices to keep them warm. In the case of a breach of this Article, it will also be considered that the Competitor has breached Article 40.9. The relevant driver will be penalised by a single penalty for the combination of both offences."
Article 40.9 further states that “a competitor may not modify any part on the car or make changes to the set-up of the suspension whilst the car is being held under parc ferme conditions.”
Therefore Russell will receive a penalty for the parc ferme breach and he will therefore start the race from the pitlane, which sees team-mate Hamilton boosted up to P17 on the grid.
