Driving a 1000 horsepower Ferrari capable of traveling in electric mode for 25 kilometers at the same time. The new Ferrari SF90 Stradale represents the new era of the Maranello-based manufacturer, thanks to the completely new style created by Flavio Manzoni and to the new plug-in hybrid powertrain combined with all-wheel drive. To all this is added the series production, the SF90 will not be produced in a limited edition, and performances never seen before starting from 1000 horsepower, the weight / power ratio of 1.57 kg / hp and an aerodynamic load of 390 kg at 250 km / h. Another novelty comes from the fact that for the first time a Ferrari V8 becomes the most powerful model in the range, surpassing the “aristocratic” V12s. Where did we go to find out how the new Ferrari SF90 Stradale Assetto Fiorano is doing? Naturally on the Fiorano circuit, where all the supercars of the Cavallino are tested
Ferrari SF90 Stradale, plug-in hybrid engine
To push the new Ferrari SF90 Stradale we find a powertrain consisting of the 780 horsepower V8 turbo engine combined with three electric motors for a total of 220 hp (162 kW): one placed between the internal combustion engine and the gearbox, and two on the front axle. . A battery with high-performance Li-ion technology powers the three motors and guarantees a range of 25km in eDrive mode, fully electric, using only the front axle. With the internal combustion engine off, the two independent front engines allow the car to reach a maximum speed of 135 km / h and also move the car in reverse. The 8-speed dual clutch gearbox has been completely redesigned and also comes the all-wheel drive. Together with the maximum specific power of 195 hp / l, the highest ever in the segment, the combustion engine declares maximum torque of 800 Nm at 6000 rpm. To achieve this result, Ferrari engineers worked on several areas of the engine, starting with an increase in displacement from 3902 cc to 3990 cc thanks to the bore now increased to 88 mm. The intake and exhaust system has been completely redesigned with a new reduced-width cylinder head with the injector positioned centrally and the adoption, for the first time on the Ferrari V8, of the GDI at 350 bar. To improve the internal fluid dynamics, in addition to the use of the larger diameter intake valve, the layout now assumes a configuration in which all the ducts are almost aligned horizontally at the height of the engine heads: the turbocharger unit has been lowered, while the exhaust line has been raised higher, as evidenced by the tailpipes in the upper part of the bumper. The turbos are now equipped with electrically controlled wastegate to improve catalyst heating and new compressor volutes.

Ferrari S90 Stradale plug-in hybrid
The operating mode of the plug-in hybrid Ferrari SF90 Stradale is managed via the new steering wheel. By acting on a special selector on the steering wheel and called eManettino (in analogy with the Manettino for managing driving controls and still present), the driver can select four different power unit management modes: eDrive: the internal combustion engine remains off and the traction is entrusted only to the electric front axle; starting from a fully charged battery, it is possible to travel up to 25km in this mode. This profile is suitable for driving in city centers, or in any situation where the sound of the Ferrari V8 could be a problem; Hybrid: this is the standard operating mode, in which the power flows are managed in such a way as to optimize the overall efficiency of the system; the control logic decides independently whether to keep the internal combustion engine on or off; if turned on, the internal combustion engine is able to work at maximum power, so as to guarantee high performance if required by the pilot; Performance: unlike the Hybrid, this mode forces the internal combustion engine to stay on all the time and favors maintaining the battery charge over efficiency, so as to ensure full availability of power as soon as it is required. This is the preferred mode in all situations in which you want to privilege driving fun; Qualify: this mode allows the maximum power of the system to be reached, as the electric motors are also allowed to work at their maximum potential (162kW); the control logic favors obtaining maximum performance, giving lower priority to maintaining the battery charge.
Ferrari SF90 Fiorano Assetto
The protagonist of our test, the SF90 Stradale under construction by Assetto Fiorano differs from the standard one for the special Multimatic shock absorbers derived from GT races, for the further lightening, thanks to the use of high performance materials such as carbon fiber (door panels , bottom) and titanium (springs, complete exhaust line) which allowed a weight reduction of 30 kg, and for the high-load rear spoiler in carbon fiber, capable of generating 390 kg of load at 250 km / h. The Assetto Fiorano equipment includes Michelin Pilot Sport Cup2 tires specially designed to improve track performance in dry asphalt conditions. They feature a softer compound and fewer grooves than those offered with basic equipment.
Ferrari SF90 Stradale interior
Climbing on board, the list of novelties continues, it is mounted for the first time on a production car, with the central cluster consisting of a single 16 ” high-definition digital screen curved towards the driver. The steering wheel is also new, now with touch controls that can control virtually every aspect of the car without ever taking your hands off the wheel. Traditional controls include the now classic little lever for driving controls, headlight control, windshield wipers and direction indicators.
