Overview | Engine parts used by F1 drivers after ten races

What are the limits?

A driver is allowed to replace the following engine parts four times: internal combustion engine (ICE), turbocharger (TC), MGU-K, MGU-H. At the beginning of the year, the FIA set the limit at three, but during the Azerbaijan Grand Prix weekend, it was increased to four. The control electronics (CE) and battery (ES) may only be renewed twice. Finally, F1 teams are also allowed to replace the exhaust system (EX), which may be done a maximum of eight times in the 2023 season.

Mercedes and Alpine the best

Mercedes are so far doing very well in terms of engine component reliability. Not even one driver with a Mercedes engine has received a grid penalty for using too many engine parts. The other team that have not yet received a grid penalty is Alpine, although Pierre Gasly is now on the edge. At Red Bull Racing, Sergio Perez has already used more parts than allowed. In Australia, the Mexican started from the pit lane, after which his team decided to give some extra parts to Perez, after all, the grid penalty had no impact. Importantly, with Daniel Ricciardo replacing Nyck de Vries at AlphaTauri, the engine parts used for that car remain the same.
