Alfa Romeo
33 Stradale

Why it matters

The 33 Stradale was a road-going version of Alfa Romeo's Tipo 33 sports-racing prototype, hand-built with a 2-litre racing V8 and Franco Scaglione bodywork. It was among the first road cars with dihedral ('butterfly') doors, and its tiny production, with no two cars identical, makes it one of the most sought-after Alfa Romeos.

Production

Every figure says what it counts.

Independent counts (e.g. engine and colour) are never combined into a calculated figure. Surviving examples are never presented as original production.

History

The first prototype was built between January and September 1967 and shown at the Monza Sport Car Show and the Turin show that November. Production cars, with two headlamps instead of the prototypes' four, were assembled by Carrozzeria Marazzi near Milan with aluminium bodies over a tubular structure, priced at 9,750,000 lire. Most went to customers, one stayed with Alfa Romeo, and several chassis were given to Pininfarina, Bertone and Italdesign for concept cars. The original plan had been for 50 cars.

Identification guide

How to tell an original from a replica or later conversion.

Production cars carry 750.33.1xx chassis numbers (first car 750.33.101); the two four-headlamp prototypes are 105.33.01 and 105.33.12. Production cars have two headlamps, some with a chrome nose 'moustache'. Details such as vents, wiper count and throttle bodies vary from car to car, so the documented chassis number is the key reference.
