The Ferrari SF90 Stradale (Type F173) is a mid-engine PHEV (plug-in hybrid electric vehicle) sports car produced by the Italian automobile manufacturer Ferrari. The car shares its name with the SF90 Formula One car with 90 standing for the 90th anniversary of the Scuderia Ferrari racing team and also "Stradale", an Italian word for "made for the road".[4]
Design
The manufacturer claims that the SF90 Stradale can generate 390 kg of downforce at 250 kph 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 drag reduction system (DRS) 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 for 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.
