The Ferrari P4/5 is a high-performance coupé car produced in a single example, and presented on August 18, 2006 in Pebble Beach, on the occasion of the prestigious Pebble Beach Concours d’Elegance.
The particular car, based on the Ferrari Enzo, was commissioned by the famous American collector James Glickenhaus, who wished to have a Ferrari Enzo that externally resembled the Ferrari 330 P3/4, a previously purchased and restored 1967 car.
In 2006 the American collector signed a contract with Pininfarina for the design, engineering and production of a unique piece based on Ferrari Enzo, subsequently named with the consent of the Maranello-based company Ferrari P4/5 by Pininfarina.
The project is developed under the responsibility of engineer Paolo Garella, head of Pininfarina Special Projects.
Although the P4/5 has many parts in common with the Enzo, more than two hundred elements have been specially created. The style of the car, under the stylistic direction of Pininfarina entrusted to Ken Okuyama, was curated by designer Jason Castriota.
The engine is the F140, a V12 with 65-degree cylinder banks of 5,998 cm³ and four valves to cylinder, the same as the Ferrari Enzo. Power output is 660 hp (485 kW) at 7800 rpm, with maximum torque of 657 Nm at 5500 rpm. The acceleration from 0 to 100 km/h is covered in 3.55 seconds and the top speed is 362 km/h.
The interiors were designed in collaboration with Glickenhaus himself, and features two new innovations, namely the integration of an Ipod and a Laptop, and the seats that have been customized to fit the collector and his son.
The P4/5 features an aluminum roll-cage (it is 165 kg lighter than the Enzo), as well as refined aerodynamics that allow for better stability and grip when cornering. Furthermore, the aerodynamic study was developed at the Pininfarina Aerodynamic and Aeroacoustic Research Center in Grugliasco, for a perfect integration and functionality of the installed aerodynamic appendages.
The style of the car is a perfect blend of past and present, a car with classic lines that connects the road GTs as if it were a bridge to the glorious prototypes that competed on the long straights of the 24 Hours of Le Mans in the roaring years of motoring.
The car cost the American tycoon a good four million dollars, and given its uniqueness its value is destined to rise to extraordinary figures.
In 2010, by the will of Glickenhaus himself, who has always been in love with Endurance racing, the Ferrari P4/5 Competizione was derived from the Ferrari P4/5 by Pininfarina, a racing car designed for use on the track.
Made on the basis of the Ferrari F430 GT2, the new project incorporates the body and the mechanical appearance of the latter, while the body is composed of quick-release elements made of carbon fiber, which reproduce much of the style of the P4/5 road.
The Ferrari P4/5 Competizione is powered by a four-liter V8 engine.
The designers chose this unit for its light weight and lower fuel consumption than the larger six-liter V12.
In 2011 the Ferrari P4/5 Competizione was taken to the Nürburgring 24 Hours race with the drivers Fabrizio Giovanardi, Nicola Larini and Manuel Lauck, where it finished in 39th place overall and in second in the E1-XP2 class (of which they part of the so-called experimental cars).
In 2012, another experimental model debuted: the Ferrari P4/5 Competizione M Hybrid, equipped with a new sports package and powered by a hybrid powertrain. The changes include the addition of a KERS system derived from Magneti Marelli capable of increasing power by 80 HP.
During the qualifying tests of the 2012 Nürburgring 24 Hours, the P4/5 Competizione M Hybrid recorded the thirtieth absolute time in 8'32"586 with the same drivers of the previous year, while in the race the car then obtained the twelfth overall and first in class for a hybrid-powered GT.
