Sebastian Vettel will take part in qualifying on Saturday despite the FIA confirming he will use a sixth power unit at Austin.
The Red Bull driver has already used his allocation of five engines this season and using an extra one would result in an automatic 10-place grid penalty while changing the entire power unit results in a start from the pitlane.
Motorsport’s governing body confirmed on Friday after Free Practice One that Vettel will have a new power unit – which includes a new engine, new turbo, new MGU-K, new MGU-H, new energy store, and new control electronics for various systems – fitted to his RB10.
Meanwhile, Red Bull team principal Christian Horner has revealed that Vettel will take part in qualifying despite his penalty.
There have been reports that the reigning World Champion could skip qualy to save mileage on his new power unit, but that won’t be the case.
“We’ll certainly be taking part in qualifying,” Horner told the BBC Sport.
“But we have to be very careful with our mileage; he has to get through three race weekends with this unit.”
