The new car, obviously an evolution of the SF90, will be presented on February 11th, much earlier than the other ones from the Scuderia’s rivals. The reason for this choice is that Scuderia Ferrari has “a very intense bench test program” for this year.
More specifically, the various components of the car will be redesigned towards footprint reduction to benefit airflow: chassis, power unit and gearbox are now an integrated structure to reduce the overall volume. In particular, the new PU’s volume has been reduced with modifications to exhaust, hydraulics and hybrid systems.
Even the suspensions structures will be integrated with elements of the car that generated downforce, since they will be directing airflow on the car’s floor and rear wing.
Obviously the main focus is to add downforce to the SF90 project without adding drag. They added new deflectors on the side to lower the direction of the airflow, and most importantly to channel the flow closer to the car structure, deviating it from hitting the rear tires, therefore increasing tire durability and making it easier to get the tires to the right operating temperatures. These mods will also speed up the flow.
Rumor talk about a new hydraulic heave damper and a much much wider cape under the nose of the car.
Now let’s talk about the new power unit, code name “Engine 065”. The power of the internal combustion engine has been increased from 850hp to 880hp. That brings the total, counting the hybrid system, to 1060hp. They opted for a “bi-metal alloy” (in theory steel) instead of an aluminum alloy to improve resistance and reduce thermal expansion, and they have introduced new internal channels to improve oil flow. These changes should improve reliability and give them the chance to use fuel with much higher heating power.
They are also experimenting a new manufacturing process for their engines called additing manufacturing, to replace the metal casting, to reduce weight and overall volume of the engine. This made necessary improving the cooling system on the cylinders, because of the higher operating temperatures.
