Presented in 2013 at the Geneva Motor Show, the Ferrari LaFerrari (project F150) is the successor of the Ferrari Enzo Ferrari (2002-2004), produced in 499 units between 2013 and 2015. It has a 6.3 V12 internal combustion engine, with a power output of 789 bhp at 9200rpm, supplemented by an electric motor and a KERS, for a final power output of 950 bhp. This makes the LaFerrari the fastest road-legal car that Ferrari has ever produced. The only track version of this car, called "FXX K" began its production in 2015. Flavio Manzoni designed this car. Its rivals are the Porsche 918 Spyder Weissach Package, McLaren P1™ and Lamborghini Asterion LPI 910-4.
