The SF90 XX Stradale delivers the most efficient aerodynamic performance of any Ferrari road car, making it comparable only to that of the LaFerrari supercar. It delivers double the maximum downforce of the SF90 Stradale, improving grip and yielding a palpably faster lap time at Fiorano. The product of Maranello’s inestimable racing experience, this result was achieved by redesigning the cooling flow management for the thermal and electric components as well the engine compartment.

The SF90 XX Stradale’s signature element is most definitely the rear fixed wing, which was thoroughly researched, tested and developed on the track-ready XXs. This is an element with enormous aero potential and has been perfectly integrated into the car’s volumes, thanks to close collaboration with the Ferrari Styling Centre. Its shape was dictated by the need to efficiently hone the way in which the pressure field created by the wing interacts with the complex pressure and backpressure systems that develop around the shut-off Gurney.

The latter, also redesigned, has two configurations: LD (Low Drag) in which the mobile element is raised, minimising drag, while in HD (High Downforce), the mobile element is lowered, uncovering the fixed area. This generates an overpressure area, which deflects the incoming flow vertically to deliver the absolute maximum downforce possible: 530 kg at 250 km/h.

The SF90 XX variants have inherited the SF90 Stradale’s PHEV layout, in which the V8 engine is integrated with 3 electric motors, 2 on each front axle and one located between the engine and gearbox at the rear, the V8 power unit itself has been made more extreme thanks to increased average compression ratio achieved by polishing the inlet and exhausts tracts as well as specific machining of the combustion chamber and pistons. In Qualifying mode, the SF90 XX can reach 62mph from a standstill in just 2.3sec and onto a top speed of 199mph.

The soundtrack of the SF90 XX has also been enhanced to produce an even fuller, richer sound.
