Based on the LaFerrari, the FXX K is the successor to the Ferrari FXX (based on the Enzo Ferrari, the LaFerrari's predecessor), with the "K" representing the kinetic energy recovery system (KERS). While based on the LaFerrari, Ferrari claims that the FXX K is a completely new model. It was unveiled at the Yas Marina Circuit in December 2014 as the third model in the XX Programmes family (excluding Evoluzione models).
In October 2017, a higher-end model that generates more downforce, the FXX K Evo, was revealed.
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?
The 6.3L (6,262 cc) naturally aspirated V12 engine, codenamed F140 FE, now pumps out 848 hp (632 kW). The HY-KERS unit has also been tuned to produce 187 hp (139 kW). In total, the FXX K produces a massive power output of 1036 hp (773 kW) and a torque figure of at least 664 ft·lb (900 N·m). New camshafts, a modified valve train, revamped intake manifolds, and mechanical tappets, along with a modified exhaust system, are implemented as well. The redline remains unchanged at 9,250 rpm, though.
The FXX K is capable of creating more than 1190 lb (540 kg) of downforce at a speed of 124 mph (200 km/h) thanks to its improved active aerodynamics. It features winglets joined by a rear spoiler that raises on vertical stabilizers. The FXX K uses the same seven-speed dual-clutch semi-automatic gearbox as the LaFerrari and remains rear-wheel drive. Weight has been reduced by 199 lb (90 kg) with the removal of many of the LaFerrari's luxuries, as well as the use of special Pirelli P Zero tires and Brembo-made carbon ceramic brakes. The FXX K also uses a multi-link rear suspension setup.
The FXX K's performance numbers include 0-60 mph (97 km/h) in 2.4 seconds, 0-100 mph (161 km/h) in 4.5 seconds, and a top speed of 214 mph (345 km/h).
The FXX K has four driving modes that control the HY-KERS unit via the "Manettino" controller. Qualify emphasizes maximum short-distance performance, Long Run is suitable for long-distance driving, Fast Charge enables a faster recharge of the battery, and Manual Boost makes the car use all power of the engine and batteries for maximum torque, cornering, and speed. The Forza renditions of the car run on the Long Run mode.
The Ferrari FXX K's improved powertrain mean an increase in its rate of acceleration, with 0-60 mph (97 km/h) in 2.4 seconds and 0-100 mph (161 km/h) in 4.5 seconds. With its aerodynamic improvements and weight reduction, the FXX K is capable of being one of the best-handling non-racing cars in the series, capable of exceeding 1.6 lateral Gs when cornering. Its braking performance has also been greatly improved with active aerodynamics working to deflect air resistance upwards. However, the FXX K is not without its disadvantages; the car struggles to pick up speed at speeds above 175 mph (282 km/h) and also has a low top speed of 214 mph (345 km/h) due to its extreme amount of downforce. However, the Hot Wheels Expansion for Forza Horizon 3 features Loop-the-Loop and Speed Bost track parts, which allow an FXX K to hit up to 233 mph (376 km/h). In summary, the FXX K is best suited for handling-intense tracks and not high-speed tracks.
Despite the Ferrari FXX K being introduced in December 2014, forzamotorsport.net lists the FXX K's year as 2016.
The Forza games correctly list the FXX K's year as 2014.
The Ferrari FXX K in the Forza series lacks a racing number.
The Ferrari FXX K's active rear wing can neither be deployed nor retracted in Forzavista.
Unlike the LaFerrari, the FXX K's glass engine cover cannot be opened either.
The Forza games show the FXX K as having a weight of 2831 lb (1284 kg).
