SF90 STRADALE: THE NEW SERIES-PRODUCTION SUPERCAR

1st August 2022

BEYOND IMAGINATION

The car’s name encapsulates the true significance of all that has been achieved in terms of performance. The reference to the 90th anniversary of the foundation of Scuderia Ferrari underscores the strong link that has always existed between Ferrari’s track and road cars. A brilliant encapsulation of the most advanced technologies developed in Maranello, the SF90 Stradale is also the perfect demonstration of how Ferrari immediately transitions the knowledge and skills it acquires in competition to its production cars.

BEYOND PERFORMANCE


ENGINE : V8
0-100 KM/H : 2.5 sec
EDRIVE POWER : 120 kW
MAXIMUM POWER @ 7500 RPM : 780 cv

The SF90 Stradale is the first ever Ferrari to feature PHEV (Plug-in Hybrid Electric Vehicle) architecture which sees the internal combustion engine integrated with three electric motors, two of which are independent and located on the front axle, with the third at the rear between the engine and the gearbox.






UNPRECEDENTED PERFORMANCE


Vortex Generator

Rear downforce is balanced at the front of the car by a complex and optimised system of vortex generators.

Although this is not its very first appearance on a Ferrari sports car, the system has been honed to the maximum on the SF90 Stradale: the front section of the chassis has been raised 15 mm compared to the central section of the chassis at the point where the vortex generators are located, thus increasing the amount of air channelled towards them and boosting their effect.

The front bumper is divided into two sections that have specific wing functions. Between the upper section and the bonnet is a pronounced indent that locally compresses the flow. This feature, together with the two diffusers ahead of the front wheels, contributes to generating downforce over the front axle.

Forged wheels

Specific aerodynamic research went into the geometry of the forged wheels which are made using a construction technology that allows greater freedom when it comes to aerodynamic solutions. The specific geometry of the wheels incorporate radial elements on the outer channel which are equally spaced between the spokes and designed to act as wing profiles.

The geometry of these profiles mean that the wheel works like a rotor blade, very efficiently managing the flows from inside the wheelarch and guaranteeing two main effects: air evacuation from wheel arch is boosted; the flow exiting the wheel rim is lined up with the longitudinal flow running along the sides.

Shut-off Gurney

The SF90 Stradale’s engine cover has been kept extremely low to improve the interaction between the flows over and under the body, and thus minimise drag.

The end section of the engine cover features a suspended wing divided in two sections: one fixed, which incorporates the third brake light, and one mobile with a wedge-shaped front area.

The latter has been dubbed the shut-off Gurney, a patented active system located at the rear of the car which regulates the air flow over the upper body, reducing drag at high speeds with low lateral dynamics loads and increasing downforce in corners, under braking and during changes of direction.

SMART COOLING FLOW MANAGEMENT

The internal combustion engine, gearbox, turbo-charged air, battery pack and electric motors, the inverters and charging systems and brakes all need cooling. Meticulous attention was paid to the design of the engine bay which houses both the usual internal combustion engine systems that generate temperatures of nearly 900°C, and highly temperature-sensitive electronic components.






DRIVING PLEASURE FOR EVERY DRIVER


The first Ferrari sports car to beequipped with 4WD

The exceptional work done to boost the power unit’s power would have all been in vain without in-depth dynamics research and the development of a whole series of solutions to boost the SF90 Stradale’s lap times, whilst simultaneously guaranteeing that drivers of all kinds could make full use of the car’s potential and have fun behind the wheel.






A FUTURE-FORWARD DESIGN


Headlights

Another signature solution is the headlights which hail a move away from the L-shaped look, to a slender slit design integrated with the brake air intakes resulting in a characteristic C-shape which lends the front of the car an original and futuristic appeal.

In an absolute first for a Ferrari, the SF90 Stradale uses matrix LED headlight technology to improve visibility in all driving conditions thanks to active beam control.



Aeronautical cockpit

More compact overhangs (the rear one is shorter than the front one in particular) and the frontward-shift of the cabin have created a cab-forward-type architecture which emphasises the fact that the engine is mid-mounted. A very low centre of gravity has also allowed the designers to lower the cabin area by 20 mm.

Combined with a more curved windshield, slender A-posts and a wide track, this creates a beautifully proportioned car with sleeker volumes.

The compact bubble-shaped cabin has an aeronautical cockpit feel and the fact that it has been shifted so far forward is further emphasised by the geometry of the two body-coloured rear flying buttresses that enclose the rear.



Tail lights

The tail lights have also evolved quite radically from Ferrari’s iconic round shape. The eye-catching, more horizontal luminous rings create a more horizontal perception of the tail lights which in turn visually lowers the height of the tail.

BEYOND TECHNOLOGY


A futuristic approach to the interface

While the SF90 Stradale’s exterior was crafred to underscore its seamless combining of form, technology and performance, the interior is even more radical. The very explicit aim there was to create a cockpit that ushered in an entirely new design direction, the effects of which would carry over into Ferrari’s entire future range.

EYES ON THE ROAD, HANDS ON THE WHEEL

The designers took a futuristic approach to the interface concept with a strong focus on creating a wraparound aeronautically-inspired cockpit with particular emphasis on instruments. This further emphasised and underscored the symbiotic relationship between car and driver. In fact, the SF90 Stradale makes an epoch changing leap forward both in formal and content terms, updating the Human Machine Interface with all-digital technology.

The Head Up Display is another part of the innovative HMI and allows various data to be projected onto the windshield within the driver’s field of vision so that their attention is not distracted from driving.

From a creative perspective, the SF90 Stradale interface project gave the Ferrari Style Centre’s designers the opportunity to interpret the screens in the cabin as a canvas on which all the car’s functions and controls could be represented. The screen graphics on the SF90 Stradale were also designed to create a 3D effect which is particularly striking during transitions, such as when the instrument panel is turned on or when swapping from one screen to the next.
