The drivers powered by Ferrari have a new engine
Ferrari has provided a new engine to all the drivers that the Scuderia powers, except Carlos Sainz.

The new parts have arrived in large numbers in Miami. For this weekend, Ferrari has brought new engines for Charles Leclerc as well as for the drivers powered by the Italian team.
For this fifth race of the season, Charles Leclerc, the Haas and Alfa Romeo drivers will have a new engine. Carlos Sainz does not have one because he already received a new one in Imola. Another driver not powered by Ferrari has a brand new internal combustion engine, and that is Pierre Gasly, who has just reached the quota for this season (3).
All the previously mentioned drivers also have, since this Friday, a new turbocharger and a new MGU-H.
Charles Leclerc, Pierre Gasly, Valtteri Bottas, as well as the Haas drivers, have also received a new MGU-H.
On their side, Lance Stroll and Nicholas Latifi have seen new batteries installed on their respective race cars starting from this weekend.
None of these drivers will receive any penalty following these changes.
