The Alfetta was the base for the GTV, a fastback coupé version of the saloon, introduced in 1974 as Alfetta GT, initially available only with the 1.8 litre (1779 cc) version of the Alfa DOHC four.[5] For 1976, with the final phasing out of the earlier 105 Series 1.3 and 1.6 litre coupes (GT 1300 Junior and GT 1600 Junior) and the 2.0 litre 105 series 2000 GTV, the Alfetta GT became a range, also available with the 1.6 litre (1570 cc) and 2.0 litre (1962 cc) versions of the same engine as the Alfetta GT 1.6, Alfetta GT 1.8 and Alfetta GTV 2000. The GTV designation was initially reserved for the 2.0 litre top version.

In 1979, some minor revisions, including a revised engine with new camshaft profiles and a change to mechanical-and-vacuum ignition advance, saw the 2.0 litre redesignated the Alfetta GTV 2000L. Autodelta also produced a limited edition turbocharged model, named Turbodelta, for FIA Group 4 homologation. This version used a KKK turbo which pushed power up to 175 PS (129 kW). The car also received a modified suspension layout. This was the first Italian production car with a turbocharger.

The styling of the GTV, while distinctive, can be seen to share many design features derived from the Montreal supercar, as translated down to a simpler and thus more marketable vehicle. Examples of this are the bonnet line, which while briefer, still has 'scallops' for the headlights, and the tail light clusters which resemble those of the Montreal. The door shape is similar, and in a sharing of parts, both vehicles employ the same door handles.

In 1981, the GTV received a restyling, with grey plastic bumpers and all matt-black trim replacing bright stainless steel, the 1.6 litre and 1.8 litre versions were discontinued and the Alfetta 2000 GTV became the base coupé model as the Alfa GTV 2.0. The Alfetta name was dropped, but the two-litre coupé retained its type designation of 11636 for left hand drive and 11637 for right hand drive. 15 inch alloy wheels were now standard, as opposed to the earlier cars' 14 inch pressed steel or optional 14 inch alloy.

GTV6: 1980–1987 / Engine: 2.5 V6

Later in the same year, the GTV-6, a version of the GTV with the SOHC V6 2.5 L engine from the Alfa 6 luxury sedan, was released. As a result the hood received a bulge to clear the top of the intake and became its most pronounced feature. With Bosch fuel injection instead of the six downdraught Dell'Orto carburettors in the early Alfa 6 installation, the V6 was much easier to start and retained its state of tune much better. The V6 received rave reviews from the motoring press, which had previously lambasted the same engine in the Alfa 6 because of the carburettor problems. It found its true home in the GTV-6 where it could stretch its legs better than in the less sporting Alfa 6 sedan, including winning the European Touring Car Championship an unprecedented four years in succession (1982–85), the British Touring Car Championship in 1983 at the hands of Andy Rouse, as well as many other racing and rallying competitions. The fuel injection installation eventually made it into the second series of the Alfa 6 as well. The GTV went through a number of revisions, including a new gear ratios and an updated interior in 1984.
