The Ferrari SF90 Stradale the new series-production supercar

The Ferrari SF90 Stradale the new series-production supercar

THE MOST POWERFUL PRANCING HORSE CAR EVER REFERENCES SCUDERIA FERRARI

Ferrari introduces a new chapter in its history with the introduction of its first series production PHEV (Plug-in Hybrid Electric Vehicle), the SF90 Stradale, images, videos and information on which can be seen on the dedicated web site: SF90stradale.com. The new model is extreme on every level and represents a true paradigm shift, because it delivers unprecedented performance for a production car. Figures such as 1,000 cv, and a weight-to-power ratio of 1.57 kg/cv, and 390 kg of downforce at 250 km/h not only put the SF90 Stradale at the top of its segment, but also mean that a V8 is the top-of-the-range model for the first time the marque’s history.

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.

The SF90 Stradale has a 90° V8 turbo engine capable of delivering 780 cv, the highest power output of any 8-cylinder in Ferrari history. The remaining 220 cv is delivered by three electric motors, one at the rear, known as the MGUK (Motor Generator Unit, Kinetic) due to its derivation from the Formula 1 application, located between the engine and the new 8-speed dual-clutch transmission on the rear axle, and two on the front axle. This sophisticated system does not, however, make for a more complicated driving experience. Quite the opposite, in fact: the driver simply has to select one of the four power unit modes, and then just concentrate on driving. The sophisticated control logic takes care of the rest, managing the flow of power between the V8, the electric motors and the batteries.

The SF90 Stradale is also the first Ferrari sports car to be equipped with 4WD, a step necessary to allow the incredible power unleashed by the hybrid powertrain to be fully exploited, ensuring the car has become the new benchmark for standing starts: 0-100km/h in 2.5 sec and 0-200km/h in barely 6.7 seconds.

Ferrari’s engineers were able to further broaden the spectrum of dynamic controls by introducing the full-electric front axle, known as the RAC-e (electronic cornering set-up regulator). As well as exclusively providing propulsion in electric drive, the two front motors independently control the torque delivered to the two wheels, extending the concept of Torque Vectoring. Fully integrated into the car’s vehicle dynamics controls, the RAC-e governs the distribution of torque, making driving on the limit much simpler and easier.

The introduction of this hybrid architecture was a challenge with regard to managing the additional weight which was resolved by an obsessive attention to detail and the overall optimisation of the whole of the car. For maximum performance in terms of overall weight, rigidity and centre of gravity, the chassis and bodyshell of the SF90 Stradale is all new, built using multi-material technology, including, for example, carbon fibre.

The development of a hybrid car of this kind demanded the development of a series of innovative aerodynamic solutions. The significant boost in the power unit’s performance brought with it an increase in the amount of heat energy to be dissipated and required the development team to carry out an in-depth review of the aerodynamic flows on the radiating masses. It also demanded new solutions to increase downforce efficiently and guarantee maximum stability at all speeds and in all driving conditions.
