We are at the stage of the season where plenty of engine changes are being made, often resulting in a grid penalty. But what about all Formula 1 drivers with regard to their used engine parts? It can be seen that half of the grid has already had to believe it, while the other half can no longer switch to a new engine or new engine part with impunity.
In 2021, if we are talking about engine parts for which you can get a grid penalty if you use more copies than allowed, we are talking about the following seven parts.
Internal Combustion Engine (ICE): max 3 pieces
Turbo Charger (TC): max 3 pieces
MGU-H: max 3 pieces
MGU-K: max 3 pieces
Energy Store (ES): max 2 pieces
Control Electronics (CE): max 2 pieces
Exhaust (EX): max 8 pieces
The drivers are allowed to use three parts of the first four parts mentioned above with impunity, and of the ES and CE only two and no fewer than eight exhausts. If you go over that, a grid penalty will follow. Below we list how many parts each driver has already used, updated until after the Grand Prix weekend in Turkey.
It can be seen that ten drivers have already received a grid penalty for changing engine parts. Ten drivers still have to fear. The next victim seems to be Vettel. He will get a new engine in the US, he confirmed. In terms of engine suppliers, only Renault, which only supplies its own Alpine with engines, is still with impunity. However, both drivers are the only ones on edge regarding all parts, including the exhaust. Alfa Romeo and Haas also have impunity, just like Aston Martin. Only one driver had to use five engines: Valtteri Bottas.
