|Although it is based on the LaFerrari, the folks from Maranello consider the FXX K to be its own model. The XX designation is more than a car, it’s a program that enables owners to race their cars at exclusive events with full factory support. The K is for the KERS system that contributes 187 additional electrical prancing horses to the total output of well over 1,000 hp. To keep the FXX K stable, it is capable of creating more than half a ton of downforce through its active-aero systems; the coolest of which are the winglets that are joined by a rear spoiler that raises on vertical stabilizers. Is it the ultimate Ferrari? If going five seconds faster than the LaFerrari at the (Fiorano) test track is a measure, well… what do you think?|
— Official description 
Introduced in December 2014, the FXX K is the track variant of the LaFerrari and the successor to the Enzo Ferrari-based FXX. Its "K" designation refers to the kinetic energy recovery system (KERS) that supplements its combustion engine.
It was in production from 2015 to 2017. Ferrari unveiled the FXX K Evoluzione on 28 October 2017, an enhanced model with 23% more downforce and 90 kg (198 lb) decrease in weight.
The FXX K uses a similar drivetrain to the LaFerrari, but with total power increased to 1036 hp (773 kW) and a torque figure of at least 664 ft·lb (900 N·m). Its redline is set at 9250 rpm.
Optimized for track racing, the FXX K has a dry weight of 2831 lb (1284 kg), and is fitted with a series of body alterations that include winglets joined by a rear spoiler that raises on vertical stabilizers. As a result it is capable of producing more than 1190 lb (540 kg) of downforce at 124 mph (200 km/h).
The FXX K emphasizes the handling-over-speed driving characteristic of the LaFerrari with more cornering grip and greater steering response, which are enabled by improved aerodynamics and a lower weight. It counts as one of the best handling cars in the Forza series, being capable of at least 1.7 lateral Gs at 120 mph (193 km/h), and also exceeds in braking performance due to being able to deflect air resistance upwards upon braking.
Powered by a 1036 hp (773 kW) drivetrain, the FXX K is also capable of recovering speed very quickly upon corner exits, as it only requires 2.4 seconds for 0 to 60 mph (97 km/h) and 4.5 seconds for 0 to 100 mph (161 km/h). Despite higher engine figures, top speed is limited to 214 mph (344 km/h) although acceleration remains largely unaffected by wheelspinning.
The FXX K is best used on handling-demanding tracks as its low top speed relative to other hypercars may be of disadvantage on high-speed courses.

- The 6.3L V12 Hybrid engine swap originates from this car.
- It is shown in the Forza series using the Long Run mode from four driving modes that control the HY-KERS unit.
- It is depicted as a 2016 model on forzamotorsport.net.
- The FXX K in the Forza series lacks a racing number.
- Its active rear wing can neither be deployed nor retracted in Forzavista. Unlike the LaFerrari, its glass engine cover cannot be opened either.
- In Forza Motorsport 7, completing a race on Mugello Autodromo Internazionale in an FXX K unlocks the Italian Tune Up achievement.
- In Forza Motorsport 7, the FXX K has a glitch where all the manufacturer colors of the car feature the exact same stripe color as with the first manufacturer color instead of different colors for the stripes for each manufacturer color.
