The Giulia TZ1 or "Tubolare Zagato" is one of the most sought after post war Alfa Romeos. It's racing successes and the stunning GTO-like looks assure its desirability.

The first TZ prototype was a Spyder on which Zagato bolted a "Coda Tronca" roof panel. A competition Giulia was introduced at the 1963 FISA Monza Cup. The competition TZ development was guided by Autodelta, a company led by ex-Ferrari engineer Carlo Chiti. The TZ shared the same basic 1,570 cc engine with the Sprint Speciale and Spider Veloce. Aiding the TZ project in its quest for aerodynamic performance was the treatment of the rear bodywork. Incorporating the research of Dr. Wunibald Kamm, the TZ used an approach called "coda tronca", otherwise known as the "Kamm tail". For ultimate streamlining, the principle is that an aircraft-like, extended tail is optimal. Since that is not practical for an automobile, Dr. Kamm discovered that there is surprisingly little increase in drag by simply chopping it at an angle. Zagato had previously proved the success of this tail treatment with their Coda Tronca Sprint Zagato Alfas, and so it was a natural evolution to adapt this to the TZ.

In 1964 the TZ1 was FIA homologated (100 units were needed for homologation to the Gran Turismo category) and immediately began logging its impressive string of race wins in Europe and North America. As the TZ program progressed and became successful, Autodelta increasingly became Alfa Romeo's racing wing, leading to an eventual acquisition by the firm.

By 1964-65, something faster was needed and this time Zagato used fiberglass to create the more aggressive TZ2, which met with considerable success during the 1966 season. Approximately 14 TZ2s chassis were built.

I am not a natural flatterer, I like to think that I "tell it like it is", politely I hope. So when I tell you that I am very impressed by the contents of your website, it is just not English politeness. I of course love the subject matter but you deal with it in an energetic and respectful manner. I am overwhelmed by the research that has gone into compiling the list of coachbuilders/bodybuilders for Europe and North America. I have never heard of the vast majority of them. Congratulations on an excellent website.
