Ferrari drivers Sebastian Vettel and Kimi Raikkonen are set to carry 10 place grid penalties into this weekend's United States Grand Prix, after the outfit elected to use a fifth power unit in both cars.
Vettel trails Lewis Hamilton in the points by 66 points but is now likely to start from the midfield after Ferrari opted to install a fifth engine into his SF15-T.
"It has always been the plan," Vettel explained. "It is not a big secret, it is not a surprise to us.
"This shouldn't be understood as a downside because we've been pushing hard and the guys managed to make big steps in terms of performance."
The pair have a penalty as they have used up their allocated four engines per season, with sanctions being introduced once a driver takes a fifth unit.
