Again in 2023, there is a limit on the number of engine parts a driver can use. A number of drivers, including Charles Leclerc, have already received grid penalties for using more parts than allowed. Championship leader Max Verstappen is still on a roll for now in terms of his number of parts used.

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, the FIA set the limit at three for the parts, but during the Azerbaijan Grand Prix weekend, this 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), this may be done a maximum of eight times in the 2023 season.

Mercedes and Alpine the best

Mercedes is 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 has not yet received a grid penalty for this 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.
