The 63rd single-seater designed and built by Scuderia Ferrari to take part in the Formula 1 World Championship is born out of a regulation change that is without precedent in this category of motor sport. Generally, in the past, regulations went in the direction of slowing down the cars. However, this year, the rule changes go in the opposite direction, meaning the cars have more aerodynamic downforce and more mechanical grip.
There are several differences between the 668 project and Ferraris from the recent past: the lengthened nose and the arrow-shaped wing are a consequence of the regulations, as is the obvious fin on the engine cover and the more complex aero appendages ahead of the air intakes on the sidepods, whose unusual shape was designed in harmony with the front crash structure. Visible at the front is a duct that has an aerodynamic role, while behind the driver, the roll-hoop, which incorporates the engine air intake has been completely redesigned. Also updated is the suspension layout, which still retains a push rod design at the front with pull rods at the rear. The hubs and wheel nuts have been redesigned to facilitate the work of the mechanics when changing wheels during the pit stops. Finally, also as a function of the expected increase in performance this year, the power-steering and braking systems have been upsized.
On the aerodynamic side, Ferrari opted to concentrate on the bargeboard and sidepod entry area, creating an very unique solution with wide air inlets high above the car's floor and completely integrated with the usual aerodynamic panels that are positioned in this area to control airflow to the back of the car.
In contrast to the aerodynamics, when it comes to the power unit, there have been few changes to the regulations. The main one concerns the amount of fuel that can be used by each car during the race: with the predicted increase in performance, with a bigger percentage of each lap spent at full revs, the permitted amount of fuel has increased from 100 to 105 Kg, although the flow rate is still fixed at 100 kg/hour.
The 062 engine is a definite step forward compared to its predecessor, when it comes to chasing performance. The layout of some of the mechanical components on the hybrid power unit has been revised, while other areas maintain a similar layout to the 2016 car. On the sporting regulation front, the abolition of the “Token” system allows the teams more room for development over the course of the season.
