LaFerrari, project name F150,[4] is a limited production mid-engine, mild hybrid sports car built by Italian automotive manufacturer Ferrari.

Nine conceptual design studies were considered for the V12 hybrid flagship in 2011, reduced to five in April 2011 (three by Ferrari Centro Stile and two by Pininfarina).

[6] LaFerrari is based on findings from testing of the FXX development prototype[5] and on research being conducted by the Millechili Project at the University of Modena.

Other changes include more efficient powertrain's control electronics, re-angled radiators to direct airflow out along the underbody rather than over the bonnet, a longer front air dam to help increase downforce, an L-shaped flap on the upper corner of each windscreen pillar to reduce compression on the rear of the cabin in the absence of a roof, different door opening angles with different wheel arches and a new carbon-fiber insert allowing the doors to rotate.

The K in the new car's name refers to the kinetic energy recovery system (KERS) which is used to maximize performance.

[25][26] 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 of the power of the engine and batteries for maximum torque, cornering and speed.

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.

[29]LaFerrari is the first full hybrid produced by the Italian automotive marque,[30] providing the highest power output of any Ferrari road car whilst decreasing fuel consumption by 40 per cent.

[31] LaFerrari's internal combustion petrol engine is a longitudinally rear mid-mounted Ferrari F140 direct fuel injected 65° V12 engine with a displacement of 6,262 cc (6.3 L) generating a maximum power output of 800 PS (588 kW; 789 hp) at 9,000 rpm and 700 N⋅m (516 lb⋅ft) of torque at 6,750 rpm,[32][2] supplemented by a 163 PS (120 kW; 161 hp) KERS unit (called HY-KERS), which provides short bursts of extra power.

The "bridge" which exists between the two seats, designed like a suspended wing, is home to other instruments linked to the dual-clutch gearbox.

The instrumentation consists of a 12.3-inch (310 mm) TFT display with the option to choose between two layouts and can host data from the telemetry system.

[41] Eighty-five LaFerrari coupés between 2014 and 2015 model years were recalled due to headrests from Lear's L32 seat failing to absorb the required amount of energy, and the tyre-pressure monitoring system displaying the wrong message when a tire suffered a puncture.

[43] Ultimately, it was put up for auction on 3 December 2016, by RM Sotheby's at the Ferrari Finali Mondiali weekend at Daytona International Speedway.
