Design
The manufacturer claims that the SF90 Stradale can generate 390 kg (860 lb) of downforce at 250 km/h (155 mph) due to new findings in aero and thermal dynamics.
The main feature of the design is the twin-part rear wing which is an application of the DRS (Drag Reduction System) used in Formula One. A fixed element in the wing incorporates the rear light, the mobile parts of the wing (called "shut off Gurney" by the manufacturer) integrate into the body by using electric actuators in order to maximise downforce. The SF90 Stradale uses an evolution of Ferrari's vortex generators mounted at the front of the car.
The car employs a cab-forward design in order to utilise the new aerodynamic parts of the car more effectively and in order to incorporate radiators or the cooling requirements of the hybrid system of the car. The design is a close collaboration between Ferrari Styling Centre and Ferrari engineers.
The rear-end of the car carries over many iconic Ferrari Styling elements such as the flying buttresses. The engine cover has been kept as low as possible in order to maximise airflow. According to the car's lead designer, Flavio Manzoni, the car's design lies in between that of a spaceship and of a race car. The rear side-profile harkens back to the 1960s 330 P3/4.[5]
Assetto Fiorano
A higher-performance version, the SF90 Stradale Assetto Fiorano, will be available as well. The Assetto Fiorano has racing-derived Multimatic shocks and lightweight carbon fibre parts embedded in the door panels and underbody. The Assetto Fiorano also employs a lightweight titanium exhaust system. These measures save 30 kg (66 lb) compared to the standard SF90 Stradale.[4]
