Sebastian Vettel has to accept a deferral in the starting lineup at the US Grand Prix.
Austin - The 34-year-old native of Hesse confirmed at the Circuit of the Americas that the engine in his Aston Martin needs to be changed.
Because the allowed number is exceeded, he gets a penalty.
For the four-time world champion, this means another setback in what was already a very mixed first season with his new team.
Before the race in Austin, Vettel finished twelfth in the ranking.
