Ferrari P45 - Mondiale dell'Automobile Paris 2006

The flat, tiled roof of the Pininfarina design studio in Turin, Italy, is a secret paradise. A short stairway above the third floor and hidden from public view, immortal automobiles appear here almost routinely. Weeks before arriving in this northern Italian city, we’d seen photos of the car standing before us now, and we’d drawn our conclusions, mostly enthusiastic. Yet seen suddenly in three throbbing dimensions, this four-wheeled aggressor seemed to morph before our eyes. Jason Castriota, an energetic native New Yorker and lead designer for Pininfarina special projects, had warned us how different a car can look in real life — and if you doubt it, consider the first Porsche Cayman you witnessed after seeing it only in pictures.

The car on the roof was something called the Ferrari P4/5 by Pininfarina — less formally, “the Glickenhaus car.” Castriota and his colleagues also designed Ferrari’s controversial new V-12 599GTB Fiorano and the show-stopping MC12-based Maserati Birdcage concept. We’d seen both downstairs — and they beggar the camera. In photos, Castriota’s all-white Birdcage is neutral, almost formless. In person, it’s one of the most muscular, sensuous automotive shapes ever, ever, ever.

The Pininfarina Rolodex is bursting with rich classic-car owners. Feelers were put out. However, the classic-car gentry only trust risk-free designs with established value, and few would risk involvement in a secret Pininfarina project that could anger Ferrari. Among world Ferraristi, one particularly wealthy American maverick came to mind — Jim Glickenhaus, 56. The Glickenhaus family’s Wall Street investment firm reinvents money daily. And besides having the wherewithal, Glickenhaus is addicted to owning priceless racing cars, among them a former Donohue Lola T70, a former McLaren/Donohue Ford Mk IV, and three Ferrari racers — a 1967 330 P3/4, a 1967 412P, and a 1947 Tipo 166 Spyder Corsa, the oldest Ferrari in existence. Nice collection.
