Introduced in 1966, GTA (where the "A" stood for Alleggerita), was the official racing version of the Giulia Sprint GT, and was produced in both road and racing versions. As usual, the racing version was entrusted to the factory competition department, Autodelta founded in 1961 as an independent company by Carlo Chiti and Ludovico Chizzola and subsequently absorbed by Alfa Romeo. Aesthetically, the road and racing versions are similar with the exception of a few details: aluminum panels, side and rear windows in Plexiglas, lightened interior finishes and linings that allow it to weigh a good 200 kg less than the road version.
With regard to the mechanical part, the intervention carried out by the racing department starting from the traditional Alfa 4-cylinder DOHC engine of 1,570 cc is notable, which is profoundly modified in the GTA. The main intervention concerns the angle between the valves which is reduced from 90 to 80 degrees, the dimensions of the valves are considerably increased and as there is no space between them to house the central spark plug, the ignition is modified with a two spark plugs per cylinder; all improvements and modifications that allow the engine to develop more than 150 HP reaching 9,000 rpm. Thanks to these characteristics and extraordinary performance, the GTA made its debut on the track, at Monza, on 20 March 1966, with Andrea de Adamich and Teodoro Zeccoli triumphing in the Jolly Club four-hour race.

THE STORY OF OUR PROTAGONIST, ONE OF THE VERY RARE 123 PRODUCED.
The example featured in our report, chassis number "AR776142", is a "Stradale" produced on 23 November 1973, painted in "Biancospino" (Alfa Romeo Historic Automobile Certification).
After the first delivery in Italy and subsequent sale in Germany, in 1983 it was imported into Japan where two years later, in September 1985, it was registered with the number plate "68.33".
The Japanese owner was the owner of a well-known historic car trading company; he bought the car in road configuration but over the years he collected many original Autodelta parts with which he gave the car a racing trim.
The following original Autodelta accessories were applied: light door with Plexiglas glass, oversized fuel tank with racing cap, oversized magnesium oil sump, rear ram, racing pilot seat, roll bar, oil cooler, racing air intake conveyor, magnesium wheels.
After 35 years, in 2018 it was sold and registered in England from where it returned to Italy to be restored bringing it back to the original specifications of the "Stradale" model. In February 2019 it was exhibited at the RM-SOTHEBY'S auction in Retromobile-Paris where it was declared sold for 263,000 euros including royalties. On 6 December 2017 it was accompanied by an ALFA ROMEO CLASSICHE certificate of origin which certifies its authenticity. On 20 November 2019 it obtained the ASI certificate of historical relevance. On 14 December 2019 it was approved by ASI with the issue of the identity certificate and the GOLD TARGA. In April 2021 it was registered in Italy.
