Ferrari Corse Clienti’s XX Programme claimed two strong successes from 2005 to 2010, first with the Enzo-based FXX model and then with the 599 GTB-based 599XX. Conceived as a means of both developing new road car systems while engaging preferred loyal customers, the XX Programme positioned these two models as track-only non-competition cars whose owners could use them in marque-sponsored events. The resulting data would be poured into a future Ferrari model, ensuring satisfaction and gain for both customer and manufacturer—the proverbial win-win.

Of course, a true successor to the FXX could only evolve with the arrival of a new Ferrari hypercar model, a milestone that eventually transpired at the 2013 Geneva International Motor Show. On the world’s greatest stage for automotive debuts, Maranello introduced the potent and beautiful hybrid LaFerrari. Once this was accomplished, it was only a matter of time before an exclusive track-only version for use in Corse Clienti events would follow. Sure enough, at the Finali Mondiali held at Yas Marina Circuit in Abu Dhabi in 2014, Ferrari unveiled the LaFerrari-based FXX K, a breath-taking fusion of form and function.

Like the LaFerrari, the FXX K was propelled by a Formula 1-derived Hy-Kers hybrid powerplant centred on a further version of the Tipo F140 V-12 engine, the F140 FF, now displacing 6.3 litres. The mill was upgraded with new camshafts with mechanical (rather than hydraulic) lifters, specially polished intake manifolds, and a new exhaust system without mufflers, contributing to an increase to 848 horsepower.

A "Manettino" dial on the centre console provided four different levels of assist from an electric motor, including one designed for “instant maximum torque delivery”, offering an additional 187 horsepower. With total output now reaching 1,035 horsepower, 85 more than the LaFerrari, this was undoubtedly a thoroughbred of unprecedented stature.

The LaFerrari bodyshell underwent numerous tweaks for optimal aerodynamic performance on the track, with the nose receiving a two-part splitter with vertical fins on either end, while the rear end was transformed with twin spoiler-ettes to manage airflow, improving downforce by as much as 50 per cent over the LaFerrari. Boasting a much more menacing stance, the FXX K is 194 millimetres longer and 59 millimetres wider than its road-going sibling, while shedding some 90 kilograms for a weight of approximately 1,255 kilograms. The improved power-to-weight ratio was evident in the new car’s testing times, as it lapped Fiorano in just 1 min 14sec, five seconds faster than the LaFerrari.

In 2017, following the pattern of the prior two XX Programme models, Ferrari began offering an Evoluzione upgrade for FXX K owners. The FXX-K Evo featured a host of aerodynamic refinements, including redesigned rear brake intakes and a fixed full-width dual rear wing that sits over an active spoiler, in total improving downforce by 23 per cent more than the FXX K; and a shocking 75 per cent more than the original LaFerrari.

As with its two predecessors, production of the FXX K was kept to a minimum with approximately 60 examples currently accounted for. It remains the most advanced product of the XX Programme to date, and for the time being, the ultimate customer-available Ferrari development car.

A SINGLE-KEEPER, FACTORY-UPGRADED EVOLUZIONE

Claiming a life of modest racing use through two ownerships, as well as a factory upgrade to Evoluzione specifications, this striking FXX-K Evo is a very desirable example. Delivered new in 2015, chassis number 212002 is presented in Bianco Italia paint with Rosso Fuoco and Argento accents, and benefits from the fastidious care of just two keepers during its lifetime. Originally designated as Programme racing car #61, the FXX K was enjoyed in Corse Clienti events during the 2016 and 2017 seasons before being upgraded to Evoluzione specifications and renumbered as car #90.

In May 2018 the Evo was acquired by the consigning owner through the esteemed marque specialists Lake Forest Sports Cars of Lake Bluff, Illinois. The car is believed to have been maintained and serviced by Ferrari through the entirety of its life.

At the time of a Ferrari technical report on file, the engine had accrued only 213 kilometres since the upgrade work, and the gearbox had accrued only 96 kilometres. At the time of the report, the front brake discs evidenced only 6 per cent wear, while the rear discs showed 0 per cent wear. Although the total odometer reading at the time of cataloguing was 5,722 kilometres, the car has accrued only 213 kilometres since the factory rebuild. These figures suggest that the FXX-K Evo has many miles of track enjoyment available for the future keeper, and the beautiful car was appropriately displayed in September 2025 at the Hampton Court Concours d’Elegance.

Given that this year marks the 20th anniversary of the successful XX Programme, there could be no better time to acquire this uber-rare techno-marvel track prodigy. As one of Maranello’s most ferociously advanced production-based track cars yet devised, chassis number 212002 would make for an outstanding acquisition for any supercar enthusiast, racing participant, or marque aficionado. The next caretaker can look forward to a warm welcome at marque-focused concours d'elegance and Corse Clienti events, or relish the unique thrill of testing the car’s limits on circuit, where the wrath of 1,035 horses can be harnessed in stunning fashion.
