Sebastian Vettel will start from the United States Grand Prix pitlane after the FIA confirmed his Red Bull-Renault will take its sixth power unit of the 2014 Formula 1 season.
The reigning F1 champion had known for some time that he would likely need an extra engine before the end of the campaign, with the USGP penciled in as the venue to take it.
In a statement issued by the FIA on Friday, it confirmed that Vettel was having a totally new power unit fitted – which included a new engine, new turbo, new MGU-K, new MGU-H, new energy store, and new control electronics for various systems. The FIA added that it been informed of the plan to change the engine on Monday.
The decision to take the new engine and all its components means that Vettel will have to start from the pits, although Red Bull boss Christian Horner has suggested that the German will still likely take part in some of qualifying.
