Ferrari has unveiled a formidable, track-focused iteration of its SF90 hybrid supercar: the Ferrari SF90 XX Stradale and its open-top counterpart, the XX Spider variant. Notably, the XX moniker, introduced by Ferrari in 2005 with the Enzo-based FXX, has traditionally been reserved for extreme track-only models. This tradition, however, has been disrupted by Ferrari with the debut of the SF90 XX duo, marking the first time road-worthy Ferraris have borne the esteemed XX badge. Moreover, it signifies the first instance since the 1995 F50 that Ferrari has adorned a road car with a prominent motorsport-style fixed rear wing. However, make no mistake, as the SF90 XX twins are designed as racetrack beasts engineered to deliver astonishing lap times.
Commencing with the design, the SF90 XX boasts an unmistakably aggressive aero package compared to the standard model. The front end features a substantial front splitter, channeling airflow towards a reconfigured underbody, while vents and scoops have been fine-tuned to enhance downforce. Notably, two ducts on each side of the front end are complemented by two additional outlets in the center of the hood. Large gills have been incorporated into both the front and rear fenders to expel air from the wheel wells. At the rear, prominent updates include twin inlets above the engine cover, an enlarged diffuser, a light strip replacing traditional taillights, and a substantial rear wing. Ferrari asserts that these advanced aerodynamic elements generate a remarkable 1,168 pounds of downforce at 155 mph.
While the SF90 XX exhibits noticeable exterior distinctions from the standard model, interior modifications are less pronounced. The cabin features an Alcantara dashboard complemented by an abundance of carbon-fiber trim. The seats have been lightened, featuring a seemingly single-piece design with adjustable backrests. The Spider and Stradale versions are nearly identical, differing only in the Spider variant’s retractable roof, which deploys in a mere 14 seconds. Impressively, it adds a mere 220 pounds to the coupe’s weight while maintaining equivalent dynamic performance.
In terms of mechanical enhancements, the SF90 XX houses a more potent iteration of the hybrid powertrain present in the standard SF90. The twin-turbo 4.0-liter V8 engine benefits from new pistons, specialized combustion chamber machining, and refined inlet and exhaust ducts, boosting output from 769 to 786 horsepower. Furthermore, the electric motors have received power upgrades, producing a combined 229 horsepower compared to the standard model’s 217 horsepower, resulting in a total output increase from 986 to 1,016 horsepower.
The vehicle retains the same 7.9-kilowatt-hour battery, maintaining an EV-only range of 15.53 miles and a top EV speed of 84 mph. Ferrari has also introduced an additional electric motor boost function, delivering increased power during corner exits to enhance lap times. According to Ferrari, this system shaves 0.25 seconds off lap times at the Fiorano circuit. The eight-speed dual-clutch transmission remains unchanged, but Ferrari has implemented software refinements. Thanks to these performance enhancements, both variants can accelerate from zero to 62 mph in just 2.3 seconds and reach a top speed of 199 mph.
Ferrari plans to produce a limited number of these models, with 799 units of the SF90 XX Stradale and 599 units of the SF90 XX Spider. Remarkably, all of these units have already been sold, with approximate price tags of $840,000 and $930,000 for the Stradale and Spider, respectively. Deliveries for the coupe are scheduled to commence in the second quarter of 2024, while the convertibles will start reaching their owners in early 2025.
