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-derived 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. With all eyes on one of the world’s greatest stages 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 breathtaking 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 type 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 1min14sec, 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 over 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.

Offered by its original owner, this 2018 Ferrari FXX-K Evo was purchased in October 2017—according to the agreement document on file. Part of the final batch of approximately only 20 FXX K examples which were delivered new from the factory with the highly desirable Evo upgrade package, chassis number 238035 is presented in Rossa Martino with Bianco Avus accents. The race number “87” boldly sits on each flank to complete the livery. At the time of cataloguing, the odometer displayed 4,244 kilometres. Meanwhile, a technical report published in June 2024 indicated 85 per suspension bushing life, 45 per cent for the driveshaft, 85 per cent on the gearbox, and 85 per cent for the engine life.

Significantly, a Corse Cliente invoice on file confirms the FXX-K received a high-voltage battery overhaul in April 2024. At this point, the complement of fluids were flushed and replaced in addition to the installation of new brake pads. The total cost for the work amounted to €68,511.89. It is further accompanied by its “Yellow Book” for special-edition models

As one of Maranello’s most ferociously advanced production-based track cars yet devised, chassis 238035 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.

Just five months after the Ferrari 488 GTB supercar premiered at the Geneva Motor Show in March 2015, its competition counterpart rolled out of the pitlane at the Vallelunga circuit in Italy for the first time. Powered by a twin-turbocharged 3.9-litre V-8 engine, the Michelotto-built 488 GTE embarked on a few early shakedown laps ahead of an exhaustive development programme in time for the 2016 motorsport season, from which Ferrari emerged with the FIA World Endurance Championship GT class Constructors’ Championship crown.

The following year, the 488 GTE swept the board. It earned the marque back-to-back Constructors’ titles, factory squad AF Corse topped the Teams’ standings, and Works drivers Alessandro Pier Guidi and James Calado were crowned LMGTE Pro champions. As BMW joined manufacturers Porsche, Ford, and Aston Martin in the bid to dethrone Ferrari, the aerodynamically revised 488 GTE Evo was introduced for 2018.

Offered here is chassis number 3844, which was issued with its accompanying Certificate of Origin on 21 February 2020. It was then sold new from the Ferrari Competizioni GT racing department to official marque dealership Garage Zenith SA of Sion, Switzerland in June. Soon put into action, the 488 GTE Evo made its debut the following month in the European Le Mans Series round at Paul Ricard. After two test session at the French venue, the car was entered by championship-winning factory team AF Corse and piloted by Swiss endurance driver Christoph Ulrich alongside team-mates Alexander West (the Swede would win that year’s GT World Challenge Europe Pro-Am Drivers’ title) and German businessman Steffen Görig. They combined to finish in 25th place overall, ranking 5th in the LMGTE class.

The trio reunited the next month for the ELMS contest at Spa-Francorchamps. Crossing the line after four hours, the Ferrari scored 29th overall and 7th in its category. For their third outing, a return visit to Paul Ricard, Ulrich and Görig were partnered by triple Brazilian Stock Car champion and two-time 24 Hours of Le Mans class winner Daniel Serra. The Ferrari factory driver helped the 488 GTE Evo to 6th in class (27th overall).

That hat-trick of ELMS events provided a solid footing ahead of an entry into the most famous of all endurance races. Due to delays brought about by the global pandemic, the 2020 edition of Le Mans was pushed back from a usual June calendar slot to mid-September. For the visit to the Circuit de la Sarthe, West reunited with team-mates Ulrich and Görig.

The AF Corse line-up had their qualifying times deleted when the stewards determined that the car had been lifted while under restricted Parc Fermé conditions. Accordingly, the Ferrari started 57th on the grid. Retirement then beckoned on lap 80, when West span through the Porsche Curves. A tap into the barrier resulted in damage to the front-left suspension.

Chassis 3844 was repaired for the ELMS season finale at the Algarve International Circuit (Portimão). Ulrich, West, and Görig climbed five places in the race but ultimately withdrew just past half distance—a legacy of Ulrich colliding with a rival Porsche. RM Sotheby’s is advised by the vendor that the repair was not deemed significant enough to return the car to Michelotto, thus AF Corse repaired the car in-house.

Since its retirement from front-line competition, the Ferrari was purchased by the consigning owner in October 2022 via Parabolica Sports of Luzern, Switzerland. Please note, a data sheet (available to view on file) issued that same year recorded the chassis to have covered fewer than 21,500 kilometres while the engine was shown to be out of life. More recently, a vehicle check and bleed of the brake system was performed by AP Racing Support in Wetzikon, south-east of Zurich, in March 2025. Chassis 3844 presents extremely attractively today in the livery configuration it wore at Le Mans.

For commentary on advisable safety-related items that may require renewal prior to the car racing again, please contact a member of the RM Sotheby’s Car Specialist team.

Should the next owner wish to add to chassis 3844’s competition history, the 488 GTE Evo remains eligible for a variety of national-level GT racing series in addition to the prestigious Club Competizioni GT official Ferrari programme.
