Ferrari customer teams Haas and Alfa Romeo have both been supplied with fresh engines in Melbourne, another sign that the Italian manufacturer's unit may be suffering from reliability issues.
In Saudi Arabia last time out, Charles Leclerc was hit with a 10-place grid penalty as a result of his team adding a third control electronics to his pool of hardware.
The Monegasque had already encountered a CE issue in the opening round in Bahrain.
As a precautionary measure, Ferrari also supplied both Leclerc and teammate Carlos Sainz with new Internal Combustion Engines in Jeddah.
While new components were added to the Scuderia's hardware inventory in Melbourne, Ferrari's customer teams – Alfa and Haas – were supplied with new ICE's for both outfits' drivers.
It's therefore the second of three ICEs authorized by the rules for the duration of the 2023 season.
The changes have not warranted any penalties as all teams remain within their annual allowance, but swapping engines as early as the third race in a 23-round season is worrying for Ferrari.
