The first hybrid supercar with a Ferrari folding hardtop (RHT) arrives. The SF90 Spider inherits the 1,000 HP PHEV hybrid drive of the SF90 Stradale.
Ferrari presents the SF90 Spider, a convertible model of the SF90 Stradale. That is the Prancing Horse’s first PHEV sequence hybrid spider, and inherits from the SF90 Stradale its excessive vary supercar setting and record-breaking efficiency, managing to extend driving pleasure and value because of the most recent RHT folding hardtop model.
Ferrari SF90 Spider retractable hardtop
The SF90 Spider can be outfitted with a retractable hardtop RHT (Retractable Laborious Prime), an answer that permits wonderful thermal and acoustic insulation within the coated configuration, no deformation at excessive speeds and most habitability because of the double curvature. The roof opens and closes in simply 14 seconds.
The roof occupies 100 liters and the usage of aluminum has allowed a saving of about 40 kg in comparison with conventional inflexible roof options. The electrical height- adjustable glass rear window additionally ensures optimum consolation in open-air use, even at excessive speeds.

Ferrari SF90 Spider options 1000hp plug-in hybrid drive
For the primary time on a Ferrari spider of the vary, the SF90 Spider provides a plug-in hybrid structure through which the interior combustion engine is built-in with two electrical motors on the entrance, which makes up the RAC-e system (Electrical Curve Trim Regulator). , and one on the rear, deriving from the expertise gained by the Prancing Horse in Components 1 and which inherits the title MGUK (Motor Generator Unit, Kinetic). The synergy between the endothermic engine and electrical motors permits reaching the utmost energy of 1000 hp.
The powertrain structure is outlined by a 780hp V8 turbo inner combustion engine, the 8-speed DCT gearbox with Ediff, the RAC-e electrical entrance axle outfitted with two unbiased electrical machines that additionally performs the operate of unique propulsion in gear electrical, by the MGUK electrical machine positioned between the engine and gearbox, by the excessive voltage battery and by the facility electronics (inverter) for the administration of the electrical motors.
Ferrari SF90 Spider, electrical gear traits
The principle power flows of the hybrid system of the SF90 Spider will be divided into two macro-areas: Provide, based mostly on the strain of the accelerator pedal by the motive force and Restoration, managed by the controller of the hybrid system.
The supply is processed by the engine management and hybrid management programs and is continually monitored by the digital management programs. Its modes will be divided into Electrical gear solely entrusted to the entrance axle (FWD mode), Hybrid gear entrusted to the thermal engine and MGUK (RWD configuration) and 4WD hybrid gear through which the electrical entrance axle is activated on-demand by the controller for traction out of corners and power restoration throughout braking.
The Restoration makes use of three methods: Regenerative braking, which is accessible on each axes each in commonplace braking circumstances within the presence of ABS; Restoration in launch (overbraking) on each axles in circumstances of launch of the accelerator pedal, managed independently on the entrance wheels; Battery charging by managing the working level of the thermal engine and rear electrical motor (MGUK).
Ferrari SF90 Spider, eDrive, Hybrid Efficiency and Qualify driving modes.
Driving the Ferrari SF90 Spider the normal Manettino is flanked by a selector for the administration of power flows referred to as eManettino. From right here you’ll be able to choose 4 driving modes: eDrive, Hybrid Efficiency, and Qualify.
In Drive, the warmth engine is off and traction is entrusted to the electrical entrance axle; on this mode, it’s potential to journey as much as 25 km with a absolutely charged battery (7.9 kWh). The velocity limiter is at 135 km / h.
In Hybrid, the automobile decides independently whether or not to activate or off the warmth engine, which if turned on can work at most energy guaranteeing excessive efficiency. The facility of the electrical motors is restricted to scale back battery consumption.
Within the Efficiency driving mode, the combustion engine is at all times saved on and the upkeep of battery cost is favored over effectivity, in order to ensure full availability of energy; additionally on this case the electrical energy is restricted to scale back battery consumption. Lastly, in Qualify, the system reaches 1000 hp of most energy.
How a lot does it weight? Decreased energy loss ratio (1.67 kg/hp)
The introduction of the hybrid structure additionally posed a problem from the standpoint of weight administration. Though the extra 270 kg of the hybrid system was largely compensated by the excess of energy delivered (220 hp, with a weight/energy ratio of the system equal to 1.23 kg/hp), a substantial amount of optimization and lightening work was required.
The whole weight of the SF90 Spider is subsequently 1670 kg and thus ensures a document weight/energy ratio, equal to 1.67 kg/hp. The notion of weight whereas driving is additional mitigated by the RAC-e electrical entrance axle which, by significantly enhancing traction and cornering stability, facilitates reaching the restrict and supplies an equal lightening quantifiable in about 200 kg.
Ferrari SF90 Spider, Fiorano Assetto
Just like the SF90 Stradale, the SF90 Spider additionally provides an extra set-up out there on request for many who intend to take the racing method to the intense.
The Assetto Fiorano differs from the usual set-up for a sequence of unique contents, together with Multimatic shock absorbers derived from the expertise of the Prancing Horse in GT competitions with adjustment optimized to be used on the monitor; use of high-performance supplies (corresponding to carbon fiber and titanium) which lighten the automobile by 21 kg; rear spoiler in carbon fiber; Michelin Pilot Sport Cup 2 tires accredited for street use; and a devoted two-tone livery (optionally available).
Ferrari SF90 Spider, how it’s made
The definition of the exterior types of the SF90 Spider follows the precept that guided the event of the SF90 Stradale, particularly the creation of a futuristic and progressive design. Regardless of the presence of the retractable roof, the Ferrari engineers have maintained the stiffness efficiency of the SF90 Stradale chassis.
The end result was achieved by reshaping the surfaces with a view to combine the tonneau cowl into the B-pillar of the SF90 Stradale, preserving the type theme. The flying buttresses behind the occupants’ heads, attribute of each Ferrari spider, are additionally built-in into the automobile’s physique. The result’s that, even with the roof off, the proportions of the SF90 Stradale are transferred to the SF90 Spider with out formal compromises. The engine, the actual jewel of the automobile, is clearly seen each with the roof closed and plein air.
Ferrari SF90 Spider, the cockpit
The inside definition was guided by the redesign of the HMI. The on-board instrumentation is sort of completely digital and the automobile is black. By urgent the ‘Engine Begin’ button on the steering wheel, a begin ceremony entails all of the parts of the pilot station till the cockpit is switched on.
The central cluster consists of a single 16 ” excessive definition digital display, curved in direction of the pilot. Within the default display, the whole lot is dominated by a giant round tachometer framed by the battery cost indicator, on the perimeters of that are the navigation display and the one on the audio controls. The massive measurement of the display permits nice flexibility in customizing the screens, which will be simply navigated utilizing the steering wheel controls. For instance, you’ll be able to view the navigator map on full display.
Due to the introduction of the head-up show, key data will be projected onto the windscreen inside the driver’s field of regard. The SF90 Spider’s steering wheel includes a sequence of multi-touch controls that permit the motive force to regulate each facet of the automobile with out ever taking his fingers off it.
The F1 bridge, attribute of the earlier fashions, disappears from the central tunnel and offers technique to a trendy reinterpretation of the gear choice gate, a real icon of handbook gearbox Ferraris. Within the new gate, the gear choice grid turns into a digitized grid for computerized transmission management.
Within the rear a part of the tunnel, there’s the ignition key housing, an actual reproduction of the horse emblem on the bonnet that turns into an actual completion of the inside type. The important thing works in full keyless mode, in order to permit not solely ignition but in addition the opening of the doorways with out being faraway from the pocket.
