Ferrari FXX-K

The "FXX K" is Ferrari's research and development vehicle based on Maranello's first hybrid, the LaFerrari. The K in the new car's name is referring to the kinetic energy recovery system (KERS) which is used to maximize performance. The FXX-K is not intended to be used in competition and was developed to give an uncompromising experience to the driver.

The vehicle was unveiled at the Yas Marina Circuit in late 2014.^[1]

Specifications

The FXX K produces a total power of 1,050 PS (772 kW; 1,036 hp) and over 900 N⋅m (664 lb⋅ft), of which 860 PS (633 kW; 848 hp) are delivered by the V12 ICE and 190 PS (140 kW; 187 hp) by the electric motor. The V12 engine has been tuned for track use as well as the HY-KERS system. With a dry weight of 1,165 kg (2,568 lb), the FXX-K has extremely effective downforce generation of 540 kg (1,190 lb) at 124 mph (200 km/h).^[2][3] The car has four driving modes: Qualify (maximum performance on short distance), Long Run (for long distance driving), Fast Charge (for faster recharging of the battery) and Manual Boost, that uses all the power of the engine and batteries for maximum torque, cornering and speed. It has F1-based technology, including the E-Diff electronic differential, F1-Trac traction control and racing ABS brakes, all controlled from the center console (Manettino). Like the preceding FXX and 599XX, the FXX K is a part of Ferrari's Client Test Driver program, that allows owners of XX cars to drive at special tracks, collecting data for use in future Ferrari road and race cars. The front of the car has a large splitter and twin-profile spoiler, the headlights are very small for improving aerodynamics. On the rear, the tail is higher and includes a electronically operated spoiler with a tail fin and a small wing in the end of each fin to maximize the downforce.

The FXX K has a power to weight ratio of 1.42 kg (3.13 lb) per horsepower.

Production

Production of the FXX K began in 2015 and continued till 2017 with a total of 40 units produced. Like the previous FXX and 599XX, the cars will be kept and maintained by Ferrari and will be available to the owners on track day events.

The FXX-K Evo was unveiled at the Ferrari Finali Mondiali 2017 on 28 October 2017 at Stazione Leopolda in Florence during the Ferrari 70th Anniversary celebration. It is an aero dynamic package available for the existing Ferrari FXX K. The Evo package allows the car to produce 23% more downforce than the standard FXX K and 75% more than the road-legal LaFerrari due to a modified front fascia, a large rear wing and underbody diffusers. Performance and weight figures are unknown but a 90 kg (198 lb) decrease in weight is said to estimated by the manufacturer. ^[5][6]

Therefore, the FXX-K Evoluzione has a power to weight ratio of 1.34 kg (2.95 lb) per horsepower.

On 29 August 2018, the FXX-K Evoluzione (number 54) was shown again to the public during the Formula 1 Milan Festival 2018 led by ex Formula 1 driver Giancarlo Fisichella.^[7]
