POWERFUL AND ELEGANT
Ferrari’s first plug-in hybrid supercar – the SF90 Stradale is also the first Ferrari sports car to be equipped with 4WD
Ferrari has introduced a new chapter in its history with the introduction of its first series production PHEV (Plug-in Hybrid Electric Vehicle), the SF90 Stradale.
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 weightto-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.
Another major innovation is the steering wheel which now has a touchpad and a series of haptic buttons that allow the driver to control virtually every aspect of the car using just their thumbs. The central instrument cluster is now entirely digital with the first automotive application of a 16” curved HD screen which can be fully configured and controlled using the controls on the steering wheel.
POWERTRAIN
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.
The internal combustion engine and the electric motors work in synergy to unleash an incredible 1,000 cv which means the SF90 Stradale sets a whole new benchmark in terms of its performance and innovative content not just with regard to the Ferrari range, but also its competitors.
INTERNAL COMBUSTION ENGINE
Thanks to its 780-cv power output, the turbo V8 featured in the SF90 Stradale raises the bar for the performance limits achievable by this type of architecture. The starting point was the F154 family engine which has won the International Engine of the Year award for the fourth consecutive year, an unprecedented achievement for any power unit.
Together with its 195 cv/l specific power output, which is the highest in the segment, the engine also delivers
800 Nm of torque at 6,000 rpm. To deliver this extraordinary result, Ferrari’s engineers focused on several different areas of the engine, starting by increasing its capacity from 3,902 cc to 3,990 cc thanks to a larger bore of 88 mm.
The intake and exhaust system was completely redesigned and now features a new, narrower cylinder head with a central injector and the adoption of 350bar GDI, another first for a Ferrari V8.
To improve the internal fluid dynamics, not only was a larger diameter intake valve adopted but the ducts are all horizontally lined up at engine head height; the turbo charger assembly has been lowered while the exhaust line is higher, as testified by the fact that the tail pipes are now in the upper section of the rear bumper. The turbos are now equipped with electronically-controlled wastegates to improve catalyser heating and new compressor volutes to optimise fluid-dynamics.
The re-engineering goes well beyond fluid-dynamics: the rationalisation of the layout has resulted in both a lower centre of gravity, thanks in part to the adoption of a smaller-diameter fly wheel, and a reduction in overall weight thanks to the use of Inconel instead of steel for the exhaust manifold. Meticulous attention was lavished on sound quality when redesigning the exhaust system and the result is fuller, richer harmonics across the entire frequency range.
7 YEARS MAINTENANCE
Ferrari’s unparalleled quality standards and increasing focus on client service underpin the extended seven-year maintenance programme offered with the SF90 Stradale. Available across the entire Ferrari range, the programme covers all regular maintenance for the first seven years of the car’s life. This scheduled maintenance is an exclusive service that allows clients the certainty that their car is being kept at peak performance and safety over the years. This very special service is also available to owners buying pre-owned Ferraris.
Regular maintenance (at intervals of either 20,000 km or once a year with no mileage restrictions), original spares and meticulous checks by staff trained directly at the Ferrari Training Centre in Maranello using the most modern diagnostic tools are just some of the advantages of the Genuine Maintenance Programme. The service is available on all markets worldwide and from all Dealerships in the Official Dealership Network.
The Genuine Maintenance programme further extends the range of aftersales services offered by Ferrari to satisfy clients wishing to preserve the performance and excellence that are the signatures of all cars built at the factory in Maranello which has always been synonymous with leading-edge technology and sportiness.
