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 version of the SF90 Stradale. This is the Prancing Horse’s first PHEV series hybrid spider, and inherits from the SF90 Stradale its extreme range supercar setting and record-breaking performance, managing to increase driving pleasure and usability thanks to the latest RHT folding hardtop version.
Ferrari SF90 Spider retractable hardtop
The SF90 Spider is also equipped with a retractable hardtop RHT (Retractable Hard Top), a solution that allows excellent thermal and acoustic insulation in the covered configuration, no deformation at high speeds and maximum habitability thanks to the double curvature. The roof opens and closes in just 14 seconds.
The roof occupies 100 liters and the use of aluminum has allowed a saving of about 40 kg compared to traditional rigid roof solutions. The electrical height- adjustable glass rear window also guarantees optimal comfort in open-air use, even at high speeds.
Ferrari SF90 Spider features 1000hp plug-in hybrid drive
For the first time on a Ferrari spider of the range, the SF90 Spider offers a plug-in hybrid architecture in which the internal combustion engine is integrated with two electric motors at the front, which makes up the RAC-e system (Electric Curve Trim Regulator). , and one at the rear, deriving from the experience gained by the Prancing Horse in Formula 1 and which inherits the name MGUK (Motor Generator Unit, Kinetic). The synergy between the endothermic engine and electric motors allows reaching the maximum power of 1000 hp.
The powertrain architecture is defined by a 780hp V8 turbo internal combustion engine, the 8-speed DCT gearbox with Ediff, the RAC-e electric front axle equipped with two independent electric machines that also performs the function of exclusive propulsion in gear electric, by the MGUK electric machine positioned between the engine and gearbox, by the high voltage battery and by the power electronics (inverter) for the management of the electric motors.
Ferrari SF90 Spider, electric gear characteristics
The main energy flows of the hybrid system of the SF90 Spider can be divided into two macro-areas: Supply, based on the pressure of the accelerator pedal by the driver and Recovery, managed by the controller of the hybrid system.
The delivery is processed by the engine control and hybrid control systems and is constantly monitored by the electronic control systems. Its modes can be divided into Electric gear only entrusted to the front axle (FWD mode), Hybrid gear entrusted to the thermal engine and MGUK (RWD configuration) and 4WD hybrid gear in which the electric front axle is activated on-demand by the controller for traction out of corners and energy recovery during braking.
The Recovery uses three strategies: Regenerative braking, which is available on both axes both in standard braking conditions in the presence of ABS; Recovery in release (overbraking) on both axles in conditions of release of the accelerator pedal, managed independently on the front wheels; Battery charging by managing the operating point of the thermal engine and rear electric motor (MGUK).
Ferrari SF90 Spider, eDrive, Hybrid Performance and Qualify driving modes.
Driving the Ferrari SF90 Spider the traditional Manettino is flanked by a selector for the management of energy flows called eManettino. From here you can select four driving modes: eDrive, Hybrid Performance, and Qualify.
In Drive, the heat engine is off and traction is entrusted to the electric front axle; in this mode, it is possible to travel up to 25 km with a fully charged battery (7.9 kWh). The speed limiter is at 135 km / h.
In Hybrid, the car decides independently whether to turn on or off the heat engine, which if turned on can work at maximum power ensuring high performance. The power of the electric motors is limited to reduce battery consumption.
In the Performance driving mode, the combustion engine is always kept on and the maintenance of battery charge is favored over efficiency, so as to guarantee full availability of power; also in this case the electric power is limited to reduce battery consumption. Finally, in Qualify, the system reaches 1000 hp of maximum power.
How much does it weight? Reduced power loss ratio (1.67 kg/hp)
The introduction of the hybrid architecture also posed a challenge from the point of view of weight management. Although the additional 270 kg of the hybrid system was largely compensated by the surplus of power delivered (220 hp, with a weight/power ratio of the system equal to 1.23 kg/hp), a great deal of optimization and lightening work was required.
The total weight of the SF90 Spider is therefore 1670 kg and thus guarantees a record weight/power ratio, equal to 1.67 kg/hp. The perception of weight while driving is further mitigated by the RAC-e electric front axle which, by considerably improving traction and cornering stability, facilitates reaching the limit and provides an equivalent lightening quantifiable in about 200 kg.
Ferrari SF90 Spider, Fiorano Assetto
Like the SF90 Stradale, the SF90 Spider also offers an additional set-up available on request for those who intend to take the racing approach to the extreme.
The Assetto Fiorano differs from the standard set-up for a series of exclusive contents, including Multimatic shock absorbers derived from the experience of the Prancing Horse in GT competitions with adjustment optimized for use on the track; use of high-performance materials (such as carbon fiber and titanium) which lighten the car by 21 kg; rear spoiler in carbon fiber; Michelin Pilot Sport Cup 2 tires approved for road use; and a dedicated two-tone livery (optional).
Ferrari SF90 Spider, how it is made
The definition of the external forms of the SF90 Spider follows the principle that guided the development of the SF90 Stradale, namely the creation of a futuristic and innovative design. Despite the presence of the retractable roof, the Ferrari engineers have maintained the stiffness performance of the SF90 Stradale chassis.
The result was achieved by reshaping the surfaces in order to integrate the tonneau cover into the B-pillar of the SF90 Stradale, preserving the style theme. The flying buttresses behind the occupants’ heads, characteristic of every Ferrari spider, are also integrated into the car’s body. The result is that, even with the roof off, the proportions of the SF90 Stradale are transferred to the SF90 Spider without formal compromises. The engine, the real jewel of the car, is clearly visible both with the roof closed and plein air.
Ferrari SF90 Spider, the cockpit
The interior definition was guided by the redesign of the HMI. The on-board instrumentation is almost totally digital and the car is black. By pressing the ‘Engine Start’ button on the steering wheel, a start ceremony involves all the components of the pilot station until the cockpit is switched on.
The central cluster consists of a single 16 ” high definition digital screen, curved towards the pilot. In the default screen, everything is dominated by a large circular tachometer framed by the battery charge indicator, on the sides of which are the navigation screen and the one on the audio controls. The large size of the screen allows great flexibility in customizing the screens, which can be easily navigated using the steering wheel controls. For example, you can view the navigator map on full screen.
Thanks to the introduction of the head-up display, key information can be projected onto the windscreen within the driver’s field of vision. The SF90 Spider’s steering wheel features a series of multi-touch controls that allow the driver to control every aspect of the car without ever taking his hands off it.
The F1 bridge, characteristic of the previous models, disappears from the central tunnel and gives way to a modern reinterpretation of the gear selection gate, a true icon of manual gearbox Ferraris. In the new gate, the gear selection grid becomes a digitized grid for automatic transmission control.
In the rear part of the tunnel, there is the ignition key housing, an exact replica of the horse emblem on the bonnet that becomes a real completion of the interior style. The key works in full keyless mode, so as to allow not only ignition but also the opening of the doors without being removed from the pocket.
