Why it matters

The Tubolare Zagato was Alfa Romeo's first Giulia designed from the start for racing, with a lightweight tubular spaceframe, an aluminium Zagato body with a low-drag nose and Kamm tail, independent rear suspension and disc brakes all round. RM Sotheby's compares its standing to Ferrari's GTO and calls it the most collectable post-war four-cylinder Alfa.

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

History

The TZ appeared in competition in late 1963 and was FIA-homologated in 1964. That year TZs took class victories at Sebring, the Targa Florio, the Nürburgring 1000 km, Le Mans and the Tour de France, finished third and fourth at the Targa Florio behind two Porsche 904s, and one won the Alpine Rally outright. The cars were road-registrable and also sold to private racers in Europe and the United States.

Artcurial credits the design to a team under Giuseppe Busso and Orazio Satta, built to answer the Lotus Elite. Production figures differ between sources, from about 112 TZs plus 12 plastic-bodied TZ2s to 117 built through 1966; the museum lists 117.

Identification guide

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

TZ chassis numbers in the cited cars fall in the 750xxx series (750006, 750066, 750087, 750097, 750100). Genuine cars can be checked against the Alfa Romeo Centro Documentazione, the Alfa Romeo Zagato Register and the Registro Italiano Alfa Romeo, which issues certificates of authenticity. RM Sotheby's notes that factory records of the era did not record engine numbers, so engine originality is hard to prove; the Tipo 511 engine carries numbers such as 00034, and racing cars used a twin-plug cylinder head. Artcurial reports an internal manufacturing number (No 812) found on several panels and a distributor plate in the engine bay showing the chassis number.
