Ferrari P4/5 by Pininfarina The Ferrari P4/5 by Pininfarina is a one-off, coachbuilt sports car created in 2006 by Pininfarina for collector James Glickenhaus. Drawing inspiration from Ferrari P4, Ferrari 330 P4, Ferrari 250 GTO and Ferrari 512 S, the project combined classical endurance-racing aesthetics with contemporary supercar engineering derived from the Ferrari Enzo, executed under the direction of designer Ken Okuyama and unveiled at events such as the Maranello Concorso and Pebble Beach Concours d'Elegance.
Pininfarina's design studio in Cambiano led the exterior reshaping of an Enzo Ferrari donor chassis, overseen by Ken Okuyama, with influence from coachbuilders like Scaglietti, Bertone, Zagato, Giugiaro, and historical racing houses including NART and Scuderia Ferrari. Styling cues referenced the 1967 24 Hours of Daytona, Le Mans 24 Hours, and Targa Florio era prototypes, echoing forms seen on the Ford GT40, Porsche 917, Aston Martin DBR1, Alfa Romeo 33 Stradale, and Matra MS670. The Pininfarina team integrated aerodynamic principles established by engineers such as Valerio Colotti, Giacomo Caliri, and designers like Leonardo Fioravanti to balance downforce and drag while preserving coachbuilt proportions reminiscent of Carrozzeria Touring and Vignale creations.
Commissioned by James Glickenhaus, the project united American collectors and Italian ateliers, involving negotiations with Ferrari S.p.A. executives, designers from Pininfarina S.p.A., and engineers linked to Maranello. The build drew on expertise from suppliers associated with Magneti Marelli, Bosch, Brembo, Pirelli, and OZ Racing, and intersected with personalities including Enzo Ferrari's legacy representatives, collectors like Peter Mullin, curators from Museo Ferrari, and concours organizers at Amelia Island and Goodwood Festival of Speed.
Mechanically, the P4/5 retained the 4.3-litre naturally aspirated Ferrari F140 V8 variant used in the Enzo Ferrari, producing similar power and torque characteristics to rivals such as the McLaren F1, Pagani Zonda, Lamborghini Murciélago, Maserati MC12, and Saleen S7. Engineering refinements referenced work by powertrain specialists from Dallara, Michelotto, and performance tuners associated with Scuderia AlphaTauri personnel, while performance testing occurred on circuits linked to Autodromo Nazionale Monza, Circuit de la Sarthe, Nürburgring Nordschleife, and the Silverstone Circuit.
The car used the Enzo's carbon-fibre monocoque and suspension geometry developed with input from carbon specialists such as Toray and Carbotech, and brake systems from Brembo; wheel and tyre packages reflected choices by Pirelli P Zero and Michelin Pilot Sport teams. Structural elements and homologation practices echoed suppliers used by Scuderia Ferrari and fabrication techniques shared with Dallara Automobili, Multimatic, and Alcoa lightweight component manufacturers. Steering, transmission, and electronic controls paralleled systems developed for the Enzo alongside calibration philosophies from Magneti Marelli and Bosch Motorsport.
As a single bespoke coachbuilt model, the P4/5 followed traditions of one-off commissions like the Rolls-Royce Sweptail, Ferrari SP12 EC, Ferrari Sergio, and historic custom jobs by Pininfarina such as the Pininfarina Battista concept lineage. The vehicle was completed in Cambiano and delivered to James Glickenhaus, after being showcased at venues like Villa d'Este Concours, Concorso d'Eleganza Villa d'Este, Villa d'Este, Concorso di Modena and later displayed in private collections and museums including The Mullin Automotive Museum and traveling exhibits organized by RM Sotheby's and Gooding & Company.
Reception among automotive journalists from outlets such as Autocar, Top Gear, Car and Driver, Road & Track, Motor Trend, and commentators like Jeremy Clarkson and Chris Harris was mixed but influential; critics compared it to coachbuilt classics from Bertone and Zagato as well as contemporary supercars from McLaren Automotive and Pagani Automobili. The P4/5 stimulated debates in institutions like RM Auctions and at events including Pebble Beach about factory identity, coachbuilding rights, and collector culture—echoing earlier controversies involving Ferrari 250 GTO restorations and bespoke commissions such as those by Pinfarina alumni. Its legacy inspired later one-offs and special projects from Ferrari Special Projects, Mansory, and Novitec and influenced retrospectives at Museo Enzo Ferrari and exhibitions curated by The National Motor Museum.
The P4/5 appeared in media coverage across publications like Forbes, GQ, Esquire, Wallpaper*, and was photographed by studios affiliated with Vogue and Vanity Fair; it featured in television segments on Top Gear and archival programs at CNN and BBC. It has been included in video-game rosters and simulation titles developed by studios such as Polyphony Digital, Codemasters, Electronic Arts, and Slightly Mad Studios while influencing design studies at Royal College of Art, IED, University of Turin, and workshops hosted by Conservatoire National des Arts et Métiers. The P4/5 continues to appear in auctions and exhibitions run by RM Sotheby's, Gooding & Company, and Bonhams and remains a reference point for collectors, designers, and historians examining the intersection of Pininfarina coachbuilding and Ferrari heritage.
