Designed by architect Flavio Manzoni, the FXX-K is based on the street-legal LaFerrari and began production in 2015

The name 'FXX-K' is actually Ferrari’s research and development program based around a laboratory car which is 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 will not be used in competing and was developed to be completely uncompromising. It uses a range of modern innovations that will ensure maximum performance anywhere.

The FXX-K produces a total of 1035 horsepower, of which 848 are delivered by the V12 ICE and 187 hp by the electric motor, with a maximum torque of over 900 Nm. The V12 engine has been tuned for track use as well as the HY-KERS system. The FXX-K has extremely effective downforce generation and the result is a downforce of 540 kg (1,190 lb) at 360 km/h (220 mph).
