Unique among internationally esteemed car shows is the Rétromobile, this year celebrating its 50th anniversary and continuing a tradition that promises surprising new discoveries for even the most seasoned car enthusiasts who attend. Held in the French capitol at the Paris Expo—Porte de Versailles from January 28 through February 1, a highlight is sure to be the Gooding Christie’s collector-car sales event on January 29, its first ever held in France. Now the official auction house of Rétromobile, Gooding Christie’s has an impressive docket, from prewar classics from Bugatti and Talbot-Lago to contemporary Ferrari hypercars.

Most notable of the latter is a rare 2018 Ferrari FXX K Evo offered at no reserve. This car is an outlier among Ferraris, not least because it’s an example of the final FXX model in Ferrari’s Programme XX, launched in 2005. FXX models were neither road cars nor racers, but essentially analytical tools intended to fast-track engineering advances, with owner-drivers behind the wheel under carefully controlled closed-circuit conditions. This elite coterie of Ferrari “test-driver clients” was hand-selected to become partners in product development that would advance Ferrari technology at every turn.

Ferrari’s then-General Manager and later CEO Amedeo Felisa explained about the cars, “The FXX will not be raced. It is a test car only.” To that end, each vehicle was fitted with a comprehensive suite of telemetry equipment to record essential track data, and owners were debriefed as if they were Formula 1 drivers, participating actively in research and paying handsomely for the privilege.

Nearly a decade since its introduction in 2017, the FXX K Evo presents specifications that remain off the charts. Developing a combined output of more than 1,000 hp, the engine is a naturally aspirated, 6.3-liter V-12 with HY-KERS (hybrid) electric-motor assist. The power plant is mated to a seven-speed ​​dual-clutch automatic gearbox. Novel then, the formula is de rigueur today for the most accomplished performance cars. Ferrari’s Enzo—made from 2002 through 2004—was a point of departure for the FXX, which revised everything including engine mechanicals, exhaust, gearbox , an all-new race-developed suspension, carbon-ceramic Brembo brakes, and even 19-inch Bridgestone racing slicks formulated for the FXX series.

Though not intended for racing, the FXX is brutal, with creature comforts conspicuously absent. The FXX Evoluzione, launched in late 2007, improving on every performance parameter by fractions of a second, with engine, gearbox, and aerodynamic improvements across the board. Importantly, the FXX Evo informed LaFerrari and subsequent XX models, including the 599XX and our subject car, the FXX K Evo. Not many FXX of any version were made, with only about 30 examples built from 2005 through 2008. In the spirit of advancement, most were upgraded to Evoluzione spec when that package was introduced.

One of approximately 40 examples of the FXX K Evo built from 2017 to 2019, this single-owner car is one of only about 10 factory-originals, as opposed to a conversion from an earlier FXX spec car. Born with Rosso paint and an interior in Nero Alcantara, it was subsequently repainted in black to match the consignor’s other FXX K Evo, which is also offered in this sale. Notably, a black FXX was given by the factory to Michael Schumacher in 2006 to acknowledge his imminent retirement from Formula 1.

Although a participant in Ferrari’s Programme XX, the car on offer has seen very little use and, according to the catalog, has been exclusively driven by factory technicians. Despite minimal mileage, reportedly less than 100 kilometers (62 miles), it underwent a major factory overhaul at Ferrari in June of 2025, the cost of which totaled more than €24,800 (approximately $29,400). The car is estimated to fetch from $5.3 million to $6.5 million when it crosses the auction block.
