Sebastian Vettel will start the United States GP at very back of the grid as Aston Martin are fitting his AMR21 with a new ICE as well as other parts.
Vettel is joining an ever-growing list of drivers requiring a fourth hybrid system with F1’s regulations stating only the first three are free, after that it is penalties for the drivers.
A new ICE means a 10-place grid drop, while taking on any additional parts – as Aston Martin plan to do – means he will be starting at the back of the grid.
The German confirmed the penalty when he addressed the media ahead of the US weekend.
