The presentation of a new Ferrari is always an event. And that the Maranello firm presents today the Ferrari SF90 XX Stradale and the Ferrari SF90 XX Spider, extreme variants of the Ferrari SF90, is no exception.
Wearing the initials XX implies that these are the most radical versions of the Ferrari SF90, whose set-up and aerodynamics are designed for use on the circuit. They will be produced in limited editions of 799 and 599 units, respectively.
However, when the lucky elite who have gotten their hands on one of these special new Ferraris receive it, they will be able to do something that no previous buyer of a Ferrari XX has been able to do: drive it street legally.
Yes, the SF90 XX Stradale and Spider, as radical as they are, are approved for road use. Definitely, this new special series is not like the others.
And it is that until now, since the Ferrari FXX derived from the Enzo in 2005, the purpose of the XX program has been to create monsters for the circuit without the need to comply with the laws of approval for road use, such as issues of emissions, free height, aerodynamic elements, etc.
It was followed by the Ferrari 599XX in 2010 and the Ferrari LaFerrari-derived FXX K in 2017. These models can only be used on the track, especially at private Ferrari events where XX owners paid to become test drivers. Ferrari explained that the recovery of telemetry and driving impressions would be used to refine future models.
This will not be the case with the new SF90 XX Stradale and Spider, which, although they can be used on the circuit, of course, can also be used to go down to Monaco or park them in Puerto Banús.
More than 1,000 HP of power
On a mechanical level, the 4.0 biturbo V8 engine located in the central rear position now produces 797 hp, compared to the previous 780 hp, reached at a speed of 7,900 rpm, although the car goes up to 8,000 rpm, with the cutoff at 8,300 rpm. Its maximum torque is 804 Nm at 6,250 rpm. The intake, exhaust, and pistons have been modified.
The combined power of the three electric motors (an MGU-K between the V8 and the gearbox, and two electric motors at the front for all-wheel drive) has been increased from 220 to 233 hp. They continue to be powered by a 7.9 kWh battery that offers 25 km of electric range in the WLTP cycle, with a top speed of 135 km/h. (In Spain it will not have a ZERO label but an ECO one).
The total power has increased from 1,000 to 1,030 hp. The transmission follows an eight-speed dual-clutch gearbox, with new developments. The SF90 XX also features an "extra boost" mode, which provides a slight boost in power for a few seconds at the push of a button.
For the first time since 1995, a street Ferrari is equipped with a fixed wing.
The most obvious changes, however, are aerodynamic, with a massive wing dominating the car's silhouette. And it is not an anecdotal fact. Ferrari has never been a fan of fixed wings on road cars, with the F40 and F50 being their last two offerings with a fixed wing.
But it was necessary to meet XX's goals of improving
downforce and also, probably, to add the visual drama that clearly
distinguishes the SF90 XX from the stock SF90.
Along with a new front splitter and an active Gurney spoiler on that same fixed wing, downforce has increased dramatically. At 250 km/h, it generates 530kg of payload (a figure valid for both the SF90 Stradale and Spider), compared to 390kg for the standard SF90. Reworked suspensions contribute, of course, to this increase in aerodynamic performance.
On the other hand, the roof panel of the Spider version is still motorized and can be opened or closed while driving at speeds of up to 45 km/h, an operation that takes 14 seconds.
In terms of performance, the SF90 XX Stradale and Spyder reach a top speed of 320 km/h, going from 0 to 100 km/h in 2.3 seconds, and from 0 to 200 km/h in 6.5 seconds.
Ferrari masters the technology that helps the driver to get the most out of the car on the track or to feel like a driver, depending on the point of view, and the SF90 XX will be no exception. Thus, it has the latest version of Ferrari's side slip control system to manage oversteer in the most aggressive dynamic modes.
It also incorporates an upgraded version of the ABS Evo system that debuted on the 296 GTB and can adjust the force at each wheel under heavy braking to maintain stability and help the car corner.
On board, the SF90 XX, the attention of the Ferrari guys has focused mainly on materials, with the upholstery combining Alcantara and technical fabrics. Carbon seats save 2.6kg, for a total weight reduction of 10kg. The car weighs 1,560 kg dry as a coupé and 1,660 kg as a Spider.
Lastly, as it is a street, Ferrari, the customer will be
delighted to know that the price of the car, still unknown in Spain, includes
routine maintenance (every 20,000 km or once a year) for the first seven years.
of life of the car.
