Ferrari presented the new SF90 XX Stradale. It is a limited edition special version based on the SF90 Stradale. The new supercar will be; also available in the SF90 XX Spider version with retractable hard top. Models that are characterized by aerodynamics taken to the extreme to offer customers even more thrills. strong when driving.
Both are approved for road use and represent the strongest version; innovative and extreme of the “special version” concept.
REFINED AERODYNAMICS 
The Ferrari technicians have worked a lot on aerodynamics. Compared to the SF90 Stradale, the maximum vertical load is; doubled, in order to ensure better grip on the track. In particular, the fixed rear wing stands out, studied, tested and developed on the cars of the ‘Programma XX’ of Ferrari. The car benefits from a larger splitter. generous compared to those of the similar element of the SF90 Stradale, defined through a detailed study in the wind tunnel. The rear speaker is also built in. been completely redesigned.
The new layout of the bottom is also a perfect fit. been optimized to increase air extraction from the radiators in front of the front wheels. The design of the lower side openings of the bumper, already developed in present on the SF90 Stradale, & egrave; however, it has been increased to reduce the back pressure. This new superar can; count on 530 kg of aerodynamic load at a speed; speed of 250 km/h.
As far as the Spider version is concerned, the retractable hard top is a must. which can be opened while running in just 14 seconds up to a speed of 1000. of 45 km/h.
Even the SF90 XX Spider can; rely on the aerodynamic solutions of the SF90 XX Stradale, combined with the specific study of the air flows in the passenger compartment with the roof open to guarantee a good level of comfort.
As far as the cockpit of the new supercar is concerned, Ferrari is the best choice. intervened through actions aimed at a significant reduction in weight. For the interiors, technical fabrics have been used and, in the functional parts, carbon fiber. The upper part of the dashboard is; in Alcantara, while the lower area is; been treated with a technical fabric.
For the SF90 XX Stradale it was; a specific racing seat was designed, with a tubular structure in visible carbon fibre.
ENGINE 
The SF90 XX Stradale (also the Spider version) inherits the powertrain of the SF90 Stradale made up of a 4-litre twin-turbo V8 engine combined with three electric motors, two on the front axle and one on the rear axle between the endothermic engine and the exchange. In this new special model, the overall power of the powertrain reaches 1,030 HP, i.e. 30 HP more; compared to the SF90 Stradale.
In particular, the unit – The 797 HP V8 is been modified to be even more; efficient by polishing the intake and exhaust pipes, as well as the adoption of new pistons and specific machining performed on the combustion chamber to increase the compression ratio. The removal of the secondary air system then made it possible to reduce the weight of the engine by as much as 3.5 kg compared to the previous application.
The supercar can; always count on a 7.9 kWh battery which allows you to have an electric-only range of 25 km. Using only electric thrusters, it is possible to; reach a speed; maximum speed of 135 km/h.
Acting on a special selector on the steering wheel called ‘eManettino’ it is Four modes can be selected; power unit management mode: in mode; ‘eDrive’ the internal combustion engine remains off and traction is on. entrusted to the electric front axle only; in ‘Hybrid’ the control logic favors the use of the energy present in the battery and manages the transitions autonomously, thus maximizing the performance. the autonomy in electric gear; in ‘Performance’ the internal combustion engine is always on and favors repeatability; of performance compared to reaching its peak; in ‘Qualifying’ the maximum power of the system is reached thanks to a control logic that favors the achievement of performance, also through the brand new functionality; of ‘extra boost’.
Then we find an 8-speed dual-clutch gearbox. Compared to the SF90 Stradale, the gear shift logic has been changed. Maranello has chosen to adopt those introduced on the Ferrari Daytona SP3.
The functionality is of Torque Vectoring, as well as; the energy recovery during braking and coasting are available in all modes; driving; The Ferrari Dynamic Enhancer in version 2.0 makes its debut on the SF90 XX Stradale, which is also active in all Manettino positions and in all grip conditions. The different systems are managed by the electronic Side Slip Control (eSSC) 1.0 system.
The makes its debut on the SF90 XX Stradalecontrol logic ‘extra boost’ directly derived from F1 which guarantees additional power for a defined time window. The objective of this function, active only in the ‘Qualifying’ dell’eManettino, is; in fact, to deliver a power peak of a suitable duration in order to improve lap times on the track.
The availability; of the additional powerit is viewable via an arc gauge on the speedometer which shows the remaining uses of ‘extra boost’, up to thirty. For this model, following the increase in power and above all the increase in aerodynamic load available, Ferrari has also revised the braking system which retains the ‘Aero’ at the front in the face of a complete redesign of the discs aimed at increasing their capacity; radiant. On the rear however, in addition to having increased the diameter of the discs and brake pads to 390 mm, full material pads were used to maximize the contact surface and improve the friction coefficient.
