After months of rumors and spy shots showing what would eventually become the Ferrari SF90 Stradale’s track-oriented variant, the Italian carmaker finally pulled the covers, and it’s called the SF90 XX Stradale. In a bit of a surprise, Ferrari also unveiled the SF90 XX Spider alongside it, featuring a retractable roof.
If the “XX” sounds familiar, the carmaker drew inspiration from its XX Program, which previously developed track-only models like the FXX-K EVO. This latest SF90, however, is entirely road legal, despite its addition of truly aggressive bodywork, a lightened interior, and even more power from its plug-in powertrain.
Like most special editions from Maranello, the Prancing Horse plans to only build 799 SF90 XX Stradale coupes and 599 SF90 XX Spiders.
It all starts with the SF90 XX’ track-ready aero components, easily some of the most aggressive we’ve seen on a road-going Ferrari in decades. Combining new elements like its extended front splitter and fixed, adjustable rear wing, the XX generates twice as much downforce as the standard SF90.
Ferrari’s latest features a redesigned front fascia with slimmer headlights, the aforementioned extended splitter, and a front hood with larger grooves. They channel cool air over the front fenders and doors, directing it into the two side pod intakes.
Ferrari updated the SF90’s cooling elements as part of its redesign by fitting more efficient radiators and rearranging the medium-heat radiators that cool its electric components. These changes allowed the XX to feature a new underbody design which helps extract hot air more efficiently.
The air that doesn’t escape under the car, such as that coming from the radiators ahead of the front wheels, is now channeled out and over the car via two S-Ducts integrated into its front hood. The XX’ front and rear louvers, like those seen in the F12 tdf, also extract air trapped in the wheel arches, contributing to its massive downforce improvements.
Out back, the changes are just as extensive, starting with new side scoops mounted just ahead of the rear radiators. These help slow and clean potentially turbulent air before it reaches the back cooling elements.
New for the XX is a rear LED light bar, replacing the Stradale’s four individual lights. It sits within a rear deck that extends further back, elongating the rear end. The fixed wing on top can be set to two positions, LD (Low Drag) or HD (High Drag) but must be adjusted manually.
Accompanying the massive new rear diffuser are vertical exhaust vents just above the rear wheels, helping extract air from the arches. The final piece is a pair of centrally-mounted exhaust tips, perhaps the only carryover from the standard SF90.
Alongside its aerodynamic and styling improvements, the XX’s electrified powertrain gets a decent power bump, combining a 3.9-liter twin-turbocharged V8 with three electric motors, one of which is bolted between its engine and transmission out back. The total system output is 1,016 horsepower, up from 986-hp in the standard Stradale.
While its V8 develops more power thanks to a higher compression ratio and new pistons, the Prancing Horse redesigned its intake plenum. Hence, it routes closer to the passenger compartment, delivering more sound to the cabin.
Its three electric motors now develop up to 230 hp, drawing power from a 7.9 kWh battery pack. The XX retains the standard Stradale’s electric mode, allowing up to 16 miles of electric-only range with an 84-mph top speed.
The XX Stradale still counts on the eight-speed dual-clutch automatic transmission that debuted in the SF90 but gains the programming developed for the Daytona SP3.
Ferrari claims a 3,439-lb dry weight figure, resulting in a slight reduction from the standard car’s 3,462-lb dry weight figure. The XX Spider has a dry weight figure of 3,659 lb, largely thanks to its folding hard top roof and mechanism.
Regarding performance stats, the XX will reach 62 mph in 2.3 seconds, 124 mph in 6.5 seconds, and top out at 199 mph. The XX Spider matches the coupe to 62 mph but is 0.2 seconds slower to 124 mph while retaining the same top speed. Its maximum speed is lower than the standard car’s 211 mph limit, most likely due to its upgraded aero components.
Inside, the XX features significant changes to its doors, which feature louvers like its wheel arches, while its center console is simplified and made of carbon fiber. The tech from the standard Stradale, such as its digital instrument cluster, remains alongside a smaller display to the driver’s right.
The final significant change is a new set of carbon-fiber racing seats, which feature hollowed-out sections to reduce weight while retaining a two-piece design. This allows the backrest to be adjusted independently while keeping a single-piece look. They’re trimmed in Alcantara, the same as the dashboard’s upper section, and offer the option of utilizing a four-point harness.
Like the standard Stradale Spider, the XX variant benefits from a retractable folding roof. However, given how extreme this special edition is, its rear deck was redesigned to work in tandem with the rest of the new aero bits. It will retract in 14 seconds at speeds of up to 28 mph.
Latest Ferrari News:
Ferrari has yet to unveil pricing for the XX Stradale or XX Spider. However, as mentioned earlier, the carmaker plans to build just 799 coupes and 599 spiders. While it was surprising to see both variants of this limited model unveiled on the same day, it wouldn’t be surprising if the carmaker announced all units have already been spoken for.
