Pininfarina Ferrari P4/5
The Ferrari P4/5 (officially known as the Ferrari P4/5 by Pininfarina) is a one-off sports car made by Italian sports car manufacturer Ferrari but redesigned by Pininfarina for film director and stock exchange magnate James Glickenhaus. The car was an Enzo Ferrari but the owner James Glickenhaus preferred the styling of Ferrari's 1960s race cars, the P Series.
The project cost Glickenhaus US$ 4 million and was officially presented to the public in August 2006 at the Pebble Beach Concours d'Elégance. Several websites were allowed to publish images of the clay model in July 2006.
On September 2009, Glickenhaus announced his intention to race a new version of the P4/5 in the 2010 24 Hours Nürburgring. The car, called the P4/5 Competizione, would not be a conversion of his road car but instead an entirely new car with a Ferrari chassis, VIN number and drivetrain. On May 2010 however, it was revealed that the Competizione would in fact be raced in 2011, based on a 430 Scuderia.
It would be built to FIA GT2 standards and raced by Scuderia Cameron Glickenhaus in an Experimental Class under the direction of Paolo Garella, former Head of Special Projects at Pininfarina. Ferrari completely distanced themselves from the P4/5 Competizione project in 2011, refusing to sell the team parts for vital engine rebuilds between races.
