Maranello, 29 June 2023 – Based on the SF90 Stradale, the new special limited series SF90 XX Stradale was unveiled today alongside its SF90 XX Spider counterpart. To be built in just 799 and 599 examples respectively, these new V8-powered PHEVs represent the latest and most extreme example of a concept of special versions, which pushes the performance of Ferrari’s road-going models to new levels.
The concept has been honed over the past 20 years or so, with many of these models quickly becoming considered benchmarks in the Prancing Horse’s line up, such as the 488 Pista and 812 Competizione. Over the same two decades, Ferrari has also developed the XX Programme to offer a select group of expert client drivers extreme cars that are not homologated for the road, but that can be driven at the very limit on the track. All of the models produced by the programme have proved a huge success, with the most recent addition being the FXX-K EVO.
Drawing on its experience in both of these spheres, Ferrari decided to create a road-legal car which embodies the maximum expression of the two programmes’ engineering concepts. The SF90 XX Stradale is based on the supercar in the range, the SF90 Stradale, and raises its already impressively exhilarating track and on-the-limit driving experience to new heights. Performance is boosted thanks to its impressive 1,030 cv (30 more than the SF90 Stradale), specific software logics and the use of radical new aerodynamics solutions, including a fixed rear spoiler – the first to appear on a road-going Ferrari since the days of the F50 – which delivers an unparalleled 530 kg of downforce at 250 km/h.
The same concept provided the inspiration for the SF90 XX Spider, which combines the ultimate on-track adrenaline rush with the heady pleasure of en plein air driving, where the iconic sound of the Ferrari V8 gives such a vital contribution. The SF90 XX Spider benefits from the same sophisticated aero solutions as the SF90 XX Stradale, as well as specifically developed cockpit air flows that guarantee superb occupant comfort with the top down. It is equipped with Ferrari’s acclaimed Retractable Hard Top (RHT), which comprises aluminium panels and not only deploys and retracts in a mere 14 seconds, but can also be activated at speeds of up to 45 km/h.
The SF90 XX Stradale has also inherited the signature PHEV layout found in the SF90 Stradale and SF90 Spider, in which the V8 internal combustion engine is integrated with three electric motors, two independent on the front axle, and one located between the engine and gearbox at the rear. This configuration allows the car to unleash a maximum of 1030 cv (+30 cv more than the SF90 Stradale), setting a whole new performance benchmark.
Like the SF90 Stradale, the SF90 XX Stradale has three electric motors, one located between the ICE and the gearbox and two on the front axle. In this instance, they deliver a maximum of 233 cv or 171 kW, thanks to the patented extra boost vehicle dynamics logic, an absolute first on a Prancing Horse road car. The SF90 XX Stradale’s high performance lithium-ion battery powers the three motors, guaranteeing a 25km range in full-electric mode. When the ICE is off, the front motors give the car a maximum speed of 135 km/h.
The control logic optimally manages the power flows focussing on either efficiency or performance as required. The driver can use the eManettino selector on the steering wheel to choose from four different power management modes. In eDrive mode, the internal combustion engine is turned off and traction is entrusted entirely to the front axle; in Hybrid mode, it favours battery energy depletion and manages transitions autonomously, maximising the full-electric range; in Performance mode, the internal combustion engine is kept running as the priority is on maintaining consistent performance, rather than on achieving the peak power; and in Qualifying, the system unleashes its maximum power output, thanks to a control logic that prioritises performance, using the brand-new extra boost function.
The SF90 XX Stradale is the most extreme version of the SF90 Stradale; its design criteria are thus those of a track car, calibrated to ensure it can be homologated for road use. That said, the SF90 XX Stradale is not just a special version: it is the first XX model to go through the factory gates, transferring the very pinnacle of Prancing Horse track technology, aerodynamic efficiency and power, to the road.
Designed by the Ferrari Styling Centre headed by Flavio Manzoni, the SF90 XX Stradale incorporates the engineering principles that underpinned the SF90 Stradale and pushes them to new extremes. Thanks to the close synergic relationship between the Styling Centre and the Technical Department, significant modifications were carried out, predominantly with the aim of increasing the downforce of the original car.
In terms of its concept, this is to all intents and purposes an XX car. Its characteristics, the fruit of a more incisive, radical design language, are even more extreme still. The SF90 XX Stradale’s styling cues are designed to highlight its thoroughbred performance characteristics whilst still retaining the pure lines and forms of its predecessor. Hence the decision not to hide air intakes and vents, a fundamental part of racing cars’ stylistic language. A technical solution that also becomes a signature element: the three louvres on the SF90 XX Stradale’s front wing and on the rear one are an example of this. As was the case with the F12tdf, these are typical cues from Ferrari’s styling language.
The guiding principle of the SF90 XX Stradale’s interior design was highlighting the cockpit’s racing vocation through solutions that would provide significant weight-savings. The main areas involved were the door panels, tunnel and mats, which are now simpler in terms of their shape and the mainly technical fabrics used, while carbon-fibre was used for functional areas. The upper part of the dashboard is trimmed in Alcantara®, while the lower part is trimmed in technical fabric. Both are inspired by the racing world.
The door panels emphasise the theme seen aboard the SF90 Stradale: the concave sections that converge on the dashboard are highlighted by the colour contrast. The three louvres in the middle zone, on the other hand are a nod to the air vents on the wheel arch, creating an overall dynamic, sculptural effect. The three apertures, which reference the exterior language, also seamlessly integrate technical and control functions, in a completely new stylistic interpretation.
