There are encouraging signs coming from Ferrari's Maranello base, with Autosport reporting that reliability targets have been met with their 2018 engine.
The reliability of the power units will be under even more scrutiny this season with the engine limit being reduced from four to three before grid penalties start coming into effect.
Ferrari's season unravelled partly due to reliability issues, but it appears the Scuderia have been learning from their mistakes.
Autosport believe Ferrari engine boss Corrado Iotti has been overseeing the development of a new cylinder head which will be rolled out later in the season without an alloy steel piston concept which was going to be introduced by ex-Ferrari chief Lorenzo Sassi.
Sassi was axed by Ferrari last year and is due to start working with rivals Mercedes now that he is close to serving his gardening leave period.
