The new 2024 Ferrari SF90 XX is among the marque’s most extreme road-going models to date. It evolves the flagship SF90 supercar with a host of technologies honed on the series of track-day specials from which it takes its name.
- Ferrari SF90 XX models develop 1,030hp, 804Nm
- All 1,398 units (799 Stradale, 599 Spiders) have been sold out
- It is the first road-going Ferrari since F50 to have a fixed rear wing
Available in Stradale (coupe) and Spider (convertible) forms, the SF90 XX is intended to “push the car on the edge” of its potential, according to development boss Gianmaria Fulgenzi. The brief was to drastically enhance performance, but to also “give the confidence to the driver to push the car at its limit”, said chief test driver Raffaele de Simone.

The car features the first fixed rear spoiler mounted to a road-going Ferrari since the F50 of 1995, and it has been added as part of an aggressive aerodynamic overhaul. This is capable of generating 315kg of downforce at 250kph, thanks in part to a trick Gurney flap system that lowers the rear deck to deflect air into the wing’s path.
To balance the aerodynamic load from front to rear and improve drivability, the SF90’s floor has been sealed off under the bonnet, into which new S-ducts have been integrated to channel hot air over the car. These vents alone contribute to a 20 percent improvement to frontal downforce, which totals 325kg at the SF90 XX’s top speed of 320kph.
The changes make the SF90 XX the most aerodynamically efficient Ferrari road car yet. De Simone added that the car’s stability is further aided by a stiffer spring set-up – reducing the body roll rate by 10 percent – and lowered rear ride height.

In addition to boosting downforce, the aerodynamic overhaul also improves the flow of cold air into the redesigned radiators, whose improved cooling performance have allowed Ferrari to unlock an additional 30hp compared to the regular SF90. This improvement is split between a 17hp uplift from the twin-turbocharged 4.0-litre V8 and 13hp on the electric motors, giving combined outputs of 1030hp and 804Nm.
The motors feature a new ‘extra boost’ system derived from Ferrari’s Formula 1 programme, providing their full output for short bursts of acceleration. Activated in the car’s Qualifying mode, it provides additional power from the electric motors at corner exit. In this mode, the SF90 XX can reach 100kph from a standstill in just 2.3sec and hit double that speed 4.2sec later.
This system is split into 30 ‘tokens’ representing the charge remaining in the 7.9kWh battery. Deploying it around Fiorano shaves 0.25sec off the SF90 XX’s lap time, using seven of the 30 tokens in the process.
Redesigned front brakes and bigger (390mm) rear discs work with the ABS-Evo system that made its debut on the Ferrari 296 GTB to improve the XX’s stopping power: it decelerates from 200kph to a standstill in 108.1m, and from 100-0kph in 29.2m.
The exhaust system has also been reworked to produce a “fuller, richer sound”, helped by new gearbox software claimed to improve the overrun noise made when lifting off the throttle at high revs.
“All the technical features we normally use for an [track-only] XX car” were integrated into the plug-in hybrid flagship, said marketing and commercial head Enrico Galliera. These include the lightest seats fitted to a Ferrari to date, contributing to a 10kg weight saving on the XX Stradale compared to the conventional SF90 Stradale that weighs 1,570kg with every lightweighting option fitted. The XX Spider weighs 1,660kg.
Ferrari has yet to disclose the lap time the SF90 XX achieved around Fiorano, but Galliera was bullish in telling our sister publication Autocar UK that the gap to the regular SF90 is “significant” – so much so that the brand deems it worthy of a dedicated announcement event later this year. The existing SF90 is the current record holder for road cars at the circuit, having lapped it in 1:19.00 (to the nearest second).
Ferrari SF90 XX Stradale, SF 90 XX Spider price
Prices for the SF90 XX started from €770,000 (roughly Rs 6.90 crore) for the Stradale coupe and rose to €850,000 (roughly Rs 7.61 crore) for the Spider. ‘Started’, past tense, is the operative word: all 1,398 examples (799 Stradales and 599 Spiders) are already accounted for, having been sold as a “reward” for “our most loyal clients”, according to Galliera. Deliveries of the Stradale begin in the second quarter of 2024, with the Spider following in the final quarter of next year.
