The limited-edition SF90 XX Stradale has been unveiled today, alongside its open-top counterpart, the SF90 XX Spider, both specially developed for road use and based on the high-performance SF90 Stradale.
Ferrari will produce only 799 units of the SF90 XX Stradale and 599 units of the SF90 XX Spider. These two plug-in hybrid models, powered by a V8 engine, represent the most advanced and revolutionary examples yet of Ferrari’s special series, pushing the performance of its road-legal vehicles to unprecedented levels.
The SF90 XX Stradale inherits the distinctive design language of the SF90 Stradale and SF90 Spider, both plug-in hybrids. It combines a V8 internal combustion engine with three electric motors—two independent units positioned at the front axle and one situated between the engine and transmission. This configuration delivers a maximum power output of 1,030 horsepower, an increase of 30 hp over the standard SF90 Stradale, setting a new benchmark in performance.
With 797 horsepower, the rear-mounted turbocharged V8 engine pushes the boundaries of this platform even further. The F154FB engine used in the SF90 XX Stradale is derived from the powertrain found in the SF90 Stradale but has been significantly enhanced. Efficiency improvements include refined air intake and exhaust ports, increased compression ratio, and new pistons and specialized combustion chamber mechanisms. Removing the secondary cooling system also reduced engine weight by 3.5 kg compared to its predecessor.
Like the SF90 Stradale, the SF90 XX Stradale features three electric motors—one located between the internal combustion engine and the gearbox, and two at the front axle. These motors deliver up to 233 horsepower (171 kW) at peak, thanks to a patented dynamic enhancement system—the first of its kind in a road-going Ferrari. The high-performance lithium-ion battery powers all three motors, enabling a full-electric driving range of 25 km. When the internal combustion engine is turned off, the front motors allow the car to reach a top speed of 135 km/h.
The SF90 XX Stradale and SF90 XX Spider are equipped with an eight-speed dual-clutch transmission, first introduced in the SF90 Stradale. However, gear-shifting has been significantly upgraded using a patented system originally showcased in the Ferrari Daytona SP3, delivering more dynamic and responsive acceleration modes. Additionally, the new system enhances the sound of gear changes by incorporating an exhaust tone that mimics the roar of high-revving engines during aggressive launches at medium to high RPMs.
In terms of aerodynamics, the standout feature is the fixed rear wing, developed using insights from Ferrari’s XX program. This wing plays a crucial role in delivering exceptional aerodynamic performance, perfectly integrated into the vehicle's design through close collaboration with Ferrari’s design center. Its shape was carefully optimized to enhance how the pressure field generated by the wing interacts with the complex airflow patterns around the closed, moving Johnnie wing.
The interior design philosophy of the SF90 XX Stradale centers on racing functionality, prioritizing weight reduction. Key areas affected include door panels, vents, and floor mats, which now feature simpler forms and technical fabrics, while functional components utilize carbon fiber. The upper dashboard is trimmed with Alcantara® fabric, while the lower section uses a technical textile—both inspired by motorsport heritage.
SF90 XX Spider
The SF90 XX Spider allows the Ferrari Styling Centre to implement modifications to the rear end, creating a distinct and instantly recognizable silhouette. The iconic flying strut seamlessly blends with the sharply pointed front profile, visually extending the car’s length forward and giving it a completely different character compared to the SF90 XX Stradale.
This gives the car a lower center of gravity, particularly from the side view. This effect is due not only to the panoramic windshield that smoothly merges with the side windows but also because the flying struts are mounted lower than those on the SF90 XX Stradale. Even though the suspension arms become visible when the roof is lowered, they are made from carbon fiber, preserving the wide, crouched appearance created by the struts. This enhances the car’s visual low-slung stance.
When the roof is raised, the suspension arms connect seamlessly, becoming a single unit with the roof structure. Like the arms, the roof itself is crafted from carbon fiber. Thanks to Ferrari’s innovative rigid folding roof mechanism, the roof can be opened or closed in just 14 seconds while traveling at speeds up to 45 km/h, allowing passengers to enjoy the car to the fullest regardless of weather conditions.
