Twenty years ago, at the 2006 Pebble Beach Concours d’Elegance, Ferrari unveiled a car that instantly became a modern legend: the Ferrari P4/5 by Pininfarina. Commissioned by American collector James Glickenhaus, it was more than a one-off supercar, it was a design statement that bridged Ferrari’s glorious past with the technology of its future.
A Call from Cambiano
More than two decades ago, James Glickenhaus received an unexpected call from Italy. On the line was Pininfarina, the famed design house, which had decided to revive its tradition of creating rare, limited one-offs for its most passionate clients.
Glickenhaus, already known for his remarkable Ferrari collection including a 166 Spider Corsa, P3/4 and 412 P, was immediately intrigued. He proposed that if they were to build a special one-off together, it should capture the soul of Ferrari’s legendary endurance racer, the 330 P4, re-imagined on a modern chassis.
A Modern Tribute to the 330 P4
The project’s foundation was a brand-new Ferrari Enzo, the last unregistered U.S. example, shipped directly to Pininfarina’s headquarters in Cambiano.
Under the direction of designer Jason Castriota, the design team set out to create a car that was road-legal like the Enzo, but infused with the sensual lines and emotional resonance of the 1960s endurance racers, without falling into retro pastiche.
More than 200 bespoke components were created for the P4/5. The chassis, gearbox, suspension, brakes and the magnificent 6.0-litre Tipo F140 B V12 were carried over from the Enzo. In just 14 months, the project was completed.
The result was breathtaking: a sleek, carbon-fibre body with improved downforce and reduced drag, delivering greater high-speed stability than the Enzo. The P4/5 became known as “the rolling DNA of Ferrari,” with subtle design cues referencing icons of the marque’s past, from its sculpted tailpipes to the butterfly doors.
Ironically, Ferrari itself had no prior knowledge of the project. Normally, such an unauthorised one-off would draw disapproval from Maranello. Yet when Luca di Montezemolo saw the finished car, he was so impressed that he granted permission for it to wear the Ferrari name officially. Thus, the car was christened the Ferrari P4/5 by Pininfarina.
The Racer: SCG P4/5 Competizione
Glickenhaus’s story with the P4/5 didn’t end there. In 2009 he announced plans to develop a race-prepared version. Working once again with Paolo Garella, who had served as project manager at Pininfarina during the development of the original P4/5, he created a competition car based on the Ferrari 430 Scuderia and 430 GT2.
This time, however, Ferrari refused to be associated with the effort. The car was therefore christened SCG P4/5 Competizione, bearing the initials of Glickenhaus’s own outfit, Scuderia Cameron Glickenhaus.
The Competizione was shorter, more aggressive, and fully carbon-bodied, with a fixed rear wing and bespoke aerodynamic detailing. It debuted at the 24 Hours of Nürburgring in 2011, finishing second in its class and 39th overall, despite battling gearbox and electrical issues throughout the race.
A year later, fitted with a Formula 1-inspired KERS system adding 50 horsepower and an aerodynamic fin for stability, it returned to secure 12th overall in the gruelling 2012 event. After that, Glickenhaus converted the car back to road-legal form, ending its competition chapter on a high note.
Legacy
The Ferrari P4/5 by Pininfarina remains one of the most celebrated one-offs ever built, a perfect fusion of design passion and engineering brilliance. It not only produced two extraordinary cars but also ignited the birth of a new marque: Scuderia Cameron Glickenhaus, which would go on to craft its own range of road and race cars, carrying forward the same independent spirit that defined the P4/5.
