Additional US Grand Prix grid penalties issued - including one pitlane start

Esteban Ocon will be forced to start the United States Grand Prix from the pitlane after Alpine changed some of his Formula 1 power unit components. Frenchman Ocon only managed to qualify 18th fastest after a tricky qualifying session at Austin, but was due to line up in 17th after a grid drop for Zhou Guanyu was applied. However, given how lowly grid position, Alpine have elected to replace Ocon's Internal Combustion Engine, Energy Store and Control Electronics. As per the technical regulations, the changes require Ocon to now start from the pitlane. Alpine have also changed the exhaust system on the A522 - but it is only the sixth one of the season, with eight permitted. Elsewhere, Yuki Tsunoda has taken a five-place drop after his gerarbox was changed. He has taken a third casing of the season - with four permitted, but the Japanese driver is now onto his fifth driveline and internal components of the campaign, with four permitted. It means Tsunoda drops to 18th with from his original 13th on the grid with Fernando Alonso, Kevin Magnussen, Daniel Ricciardo, Mick Schumacher and Zhou all shuffling forward one spot.
