Alfa Romeo
Giulia Sprint GTA (Stradale)

Why it matters

The GTA, introduced in February 1965, took the Giulia Sprint GT and reworked it into a lightweight competition coupé; the "A" stands for alleggerita, lightened. RM Sotheby's describes it as a transformation from affordable sports car to giant-killer, and notes that most GTAs, even Stradale road versions, were used for racing.

Production

Every figure says what it counts.

Independent counts (e.g. engine and colour) are never combined into a calculated figure. Surviving examples are never presented as original production.

History

RM Sotheby's says the body was aluminium apart from the roof, which it describes as a Peraluman 25 alloy panel, with alloy used widely in the inner structure, Perspex side windows and no sound deadening. The Stradale road version kept bucket seats and a minimal rear seat. Most cars had a twin-plug cylinder head with reworked ports, larger sump, oil cooler, high-compression pistons and hotter cams; the driveline got a lightweight flywheel, magnesium bell housing, limited-slip differential and hollow shafts.

The auction house reports that specification varied from car to car, and that undisturbed original GTAs are rare. The example it describes was completed on 22 June 1965 according to Alfa Romeo's Centro Documentazione.

Identification guide

How to tell an original from a replica or later conversion.

Genuine GTAs can be confirmed through the Alfa Romeo Automobilismo Storico Centro Documentazione, which can state the completion date of a given chassis. Features listed by RM Sotheby's for the Stradale include alloy body panels and inner structure, Perspex side windows, a Peraluman 25 roof, a twin-plug head on most cars, magnesium bell housing, limited-slip differential and hollow half shafts, though specification differed between cars. FIA papers and the original registration record support a car's identity.
