Founded by former Alfa and Ferrari engineers, Carlo Chiti and Lodovico Chizzola, Auto-Delta was a tuning company that became Alfa Romeo’s official race department some three years after the Italian tuner’s inception in ’61. Of the shop’s many successful race vehicles was the Alfa Romeo Alfetta GTV Turbodelta GR.4, a turbocharged, lifted rally version of Alfa’s then-newly-redesigned 2.0L Alfetta GTV 2000L built for FIA Group 4 homologation.
Putting down around 150hp and 170ft-lbs of torque, the blown 2.0L inline-four is said to be the first-ever Italian-made production car (if you can call it that). Only 400 units were produced over its two-year production run, all of which were built to full rally-spec. And while a great number of examples were driven into the ground over years of competition, one remarkably clean genuine Turbodelta GR.4 has just surfaced for sale. This particular 1979 example’s original owner was Alfa Romeo SPA itself, which suggests it was a factory test mule for Alfa’s high-level rally development efforts. The seller fails to cite any specifics, but says this specimen features a number of “unique modifications.” This Auto-Delta-built 1979 Alfa Romeo Alfetta GTV Turbodelta GR.4 is for sale through Italy’s Ruote da Sogno, where the price is available upon request.
