The Alfa Romeo Junior Z was a limited production two-seater coupé with aerodynamic bodywork by Zagato of Milan. The kamm tail wedge-shaped body was designed by Ercole Spada at Zagato. The rear boot lid could be opened a crack (electrically operated) so as to aid in cabin ventilation. The Junior Z was introduced at the 51st Turin Motor Show in November 1969. Unlike Zagato's earlier, race-oriented and aluminium-bodied Giulietta SZ which had a very active competition history, the Junior Z was not specifically intended for racing and did not see much use in competition.
In total 1,117 examples were built, of which 2 bodyshells were destroyed during production because they were not within specification. Production of the Junior Z continued through 1972, and was replaced by the 1.6-litre 1600 Junior Z at the end of the year; although according to the records two more 1.3-litre cars were completed in 1972.
