Corrado Iotti, head of development for the power unit, and Guido di Paola, head designer have signed off their 2019 PU known as ‘064’.

According to rumors in the Italian media, the SF90 car will be easily recognizable because it should have a more streamlined 064 engine airbox than it has been in the last two years. The feeling is that the SF90 returns to a dynamic grip more similar to that of 2017 to have a much more efficient engine cover as a result of a different location of the accessories of the PU, which allowed them to reduce the section for the benefit of greater cleaning of the flows to the rear wing.

In addition to this, oil burning for engine performance has been stamped on, so Ferrari appears to be looking toward higher burn efficiency of the fuel itself to compensate hence the steel cylinders, but they compensate for the increase in overall weight by using new materials for the cylinder head. The process uses a unique metal powder to build components directly from the CAD file via bed-fusion technology.

It is this innovative technology that makes it is possible to create parts that have increasingly complex geometries and very thin walls that could not be obtained with more traditional methods.
