SUPERCAR  WORLD AND ITALIAN EXCELLENCES
told by true lovers of "MADE IN ITALY"

Ferrari SF90 Stradale the first hybrid

1,000 horses, 0-100 km / h in 2.5 "and 25 km zero emission at a maximum of 135 km / h.

It is the most powerful road Ferrari ever.

Due to its existence and its general success, hybrids have a permanent home in the Ferrari team. The 949 horsepower Cavallino Rampante (707 kW) has shown that, even for a company so rich in history, progress is perpetually part of the plan. And the latest Ferrari product is no exception.

It was preceded on the hybrid road by LaFerrari, which stands for this SF90 Stradale as - obviously we exaggerate - a G91 fighter is for a Eurofighter; already because today the progress is tumultuous, the desire to excel more and more thrust and that of owning an object if not unique, however very rare, spasmodic, for those who obviously can afford it.

Production will start in the second half of the year and the first deliveries will start in 2020, but the new Ferrari SF90 Stradale has already conquered a star role in the firmament of the new generation supercars, as evidenced by the booking requests already arrived from the middle world, without knowing the price (it is assumed between 500 and 600,000 euros).

The preview presentation that took place last week in Fiorano has in fact revealed a masterpiece of style, innovation, technology, capable of marking an epochal turning point in the history of the Cavallino and of relegating the disappointments suffered in Formula 1 to the background.

Without complexes, in fact, the men of Maranello have assigned the new jewel the same name as the racing single-seater, adding Stradale to the initials SF90, which indicates the 90th anniversary of the foundation of the Ferrari team. A choice consistent with the historic vocation of this company, which has always made competitions the ideal test bench for developing advanced technologies that can be transferred to road cars.

SF90 Stradale: result of expertise in competitions

 

Not that in Ferrari they were completely fasting from the study of hybrid power supplies: the LaFerrari hypercar, from the technology that it inherited a lot from the expert tise in F1, is a demonstration of this. It is, however, an "dream" ultra-supercar, like - always to continue with some of the most fitting examples -  Porsche 918 , McLaren P1 , Mercedes-AMG Project One, Koenigsegg Regera. Vehicles that (to find them!) Require huge investments to get a copy. However, they (like LaFerrari) have been designed to highlight the state of the art in the field of hybrid propulsion, a technology that - thanks to the constant development in competitions, the "voice" to which Ferrari has always been in tune - today is gradually "Exported" also in the supercoupé sector, not necessarily "hyper".
 

SF90 Stradale: 1.000 CV hi-tech

 

“Arid figures” which nevertheless help to understand the technological level reached by Ferrari designers in the development of the new SF90 Stradale: 1,000 round round CV on a dry weight of 1,570 kg; the award-winning 3.9-liter turbocharged V8 combined with three electric motors (one of which, placed behind between the gearbox - also of a new design - and the thermal unit, derives from the application in Formula 1 and for this inherits the name MGUK , or Motor Generator Unit, Kinetic) which provides the Maranello plug-in hybrid novelty with a very favorable weight / power ratio (just 1.57 kg / HP); and, on the road, a declared maximum speed of 340 km / h, 2 "5 for shooting from 0 to 100 km / h and just 6" 7 to splash from 0 to 200 km / h. All this, controlled through an eSSC-electric Side Slip Control management unit and by numerous systems for steering the hybrid module, the traction and the vehicle dynamics: eTC-electronic Traction Control system, brake torque distribution control between the hydraulic system and brake-by-wire electric motors, Torque vectoring and four driving modes.

Three electric units and a 4.0-liter V8 for 1,000 HP

 

Except that unlike the British fireball, the Italian one shows the technique. The 1,000 hp power and 1,200 Nm torque system is based on the 4.0-liter V8 engine mounted fearfully close to the ground. The three electric units (one for each of the front wheels and one at the rear) ensure another 220 HP (potentially 435) which add up to the 780 of the 800 Nm thermal engine. The transmission is new and with a double eight-speed clutch. The lithium-ion battery has a capacity of only 7.9 kWh, because the idea of traveling with zero emissions obviously does not intrigue too much for Ferrari drivers.

Ferrari SF90 Stradale: the most powerful V8 ever

 

In detail, the "PHEV" Ferrari is equipped, with regard to the thermal unit, with the well-known V8 3.9 turbo of the F154 family, which in recent days has received in Stuttgart the fourth consecutive recognition (a record!) As "International Engine of the year ". The architecture of the "Ottovù" of Maranello is well known, not surprisingly, 488 GTB, 488 Pista and 488 Spider and F8 Tributo are currently adopted, as well as GTC4LussoT and Portofino, and Maserati Quattroporte GTS. With regard to the new location, the thermal unit has been further "revised and corrected", with the stated objective of moving the performance limits achievable by this architecture by one notch.

It is the fastest road Ferrari ever (340 km / h) with astounding acceleration capabilities (0-100 in 2.5 seconds). If that was not enough, it is also the first that can be opened and started with the key in your pocket. The basic engine is the 780 hp V8 turbo recently winner, for the fourth consecutive year, of the "engine of the year" award, but with a displacement increased from 3,902 to 3,990 cc; in addition there are the three electric motors (two arranged at the front, one behind) which bring another 220 hp. The three units are powered by a lithium ion battery rechargeable to a power outlet (plug-in system) which ensures, as mentioned, 25 km of autonomy in electric mode. The two independent front engines allow the SF90 Stradale to reach 135 km / h, but the most important aspect is that, with the V8 off and the motion ensured by the electric units, this Ferrari can have access to the ZTL, proving itself to all effects a car in line with changing times. That said, we are still in the presence of a high-performance supercar "built to dare, to go further", as the head of technological development Michael Leiters points out, illustrating the work done to contain the weight (1570 kg, thanks to the use of materials such as carbon fiber, aluminum, titanium, magnesium), to improve aerodynamics (thanks to the Flavio Manzoni Style Center), to optimize the man-machine relationship (with steering wheel and instrumentation inspired by Formula 1).

Driving modes and aids

 

Four driving modes:

  • eDrive: electric drive only
  • Hybrid: the system manages the power independently, adapting to the implicit requests of the driver
  • Performance: favors the use of the internal combustion engine
  • Qualify: here it draws on all available power (internal combustion engine + 3 electric motors on the two axles for an all-wheel drive however sui generis - e-4WD - since there is no central differential)

The electronic aids package rests mainly on the eTC (Electronic Traction Control), the Torque Vectoring on the front axle and the brake-by-wire braking system that optimally balances hydraulic power, electric motor brake and regenerative recovery when braking.

Performance

Before moving on to the performance data, we want to remember that the SF90 Stradale in the dry lap on the Fiorano test circuit, gained on the LaFerrari, about 1.5 seconds.

■ Starting from a standstill: 0-100 km / h in 2.5 ", 0-200 km / h in 6.7"
■ Maximum speed: 340 km / h
■ Autonomy in «zero emissions» mode: 25 km
■ Maximum speed in «zero emissions» mode: 135 km / h
