Description Autodelta, the racing division of Alfa, developed a car for competitions named GTA instead of GT, the 'A' standing for 'Alleggerita', Italian for lightweight. The GTA was produced first in 1965 as a 1600 (1570 cc) and later as a 1300 Junior version. The GTA automobiles were also manufactured in either street (Stradale) or pure race (Corsa) trim, as painted here.
