Ferrari P4/5 by Pininfarina

P4/5 in brief

The P4/5 was built as a single unit to order — its commissioner was American collector and director James Glickenhaus. The design was by Pininfarina, and the name is a nod to famous Ferrari racing prototypes.

This isn't a production model but a bespoke collector's item. It's not for sale on regular classifieds sites and only appears at the rarest of events or auctions.

Technology and design

The P4/5 is based on the Ferrari Enzo, so it has the same 6.0-litre V12 engine with around 650bhp and a semi-automatic gearbox with paddle-shift controls. That means driving dynamics remain at supercar level.

The body is all-new — low, wide and sleek, with a cabin reminiscent of racing prototypes. The design deliberately eschews modern Ferrari shapes and harks back to the legends of the 1960s.

Later history

The P4/5 was unveiled in 2006 and garnered huge attention as one of the most striking one-off cars. Its owner later continued this project and created a racing-ready variant.

Due to its unique origins, the P4/5 is considered one of the most striking stories of modern Ferrari customisation, with its value depending on its history rather than the manufacturer's price list.

What to know about such cars

One-off cars don't have a traditional market price—the value is determined each time individually and depends on the history and the owner. Before buying, check the provenance and documents.

Maintenance should be entrusted to Ferrari specialists, as some parts may be made specifically for this car. Also, consult on registration and permits to use on public roads.

Trim levels

Names and equipment vary by market and year; we list the versions most commonly found in Europe.
