Alfa Romeo TZ1

Designed by Orazio Satta and Giuseppe Busso at Alfa Romeo, the “TZ” was produced together with Autodelta, which was responsible for the development of the propulsion engine and of the assembly, with the SAI Ambrosini, responsible for the production of the tubular frames and with the Zagato, in charge of the bodywork with tubular chassis here named TZ “Tubolare Zagato”.

It featured a 1,570 cc twin cam engine shared with the Giulia TI and powered by 112 hp at 6500 rpm, was enhanced over the years to reach even 160 hp.

The key strength of this racing car was certainly its lightness. The light weighted tubular chassis (only 62 kg) matched with an aerodynamic bodywork developed by Abarth for the speed records , a light weighted aluminum engine, the disc brakes on the four wheels with independent suspensions and the magnesium wheels, gave to this "bullet” an incredible total weight of only 660 kg and a top speed of 240 km/h.

In order to increase performances was used a style called "coda tronca" in Italian, meaning "short tail”, incorporating the research of Dr. Kamm, that gave this car an innovative aerodynamic profile.

The car debuted in 1963 and after the homologation, it started to take more class wins both in Europe and North-America.
