📚 Vehicle History

Brand Heritage:

Alfa Romeo has a long and storied history in motorsport and automotive engineering, renowned for its sporty character, distinctive styling, and passionate following.

Model Evolution:

The Alfetta was introduced in 1972 as a successor to the Giulia sedan. The 1977 model represents an update within the first generation (Type 116). It was available in both 4-door sedan and 2-door coupe (Alfetta GT/GTV) body styles, with the GTV being a particularly acclaimed performance variant.

Production Years:

1972-1987 (Alfetta Sedan), 1974-1985 (Alfetta GT/GTV).

Transaxle Innovation:

The Alfetta's transaxle design, placing the gearbox and differential at the rear, was a significant engineering feature intended to improve handling dynamics by achieving near-perfect weight distribution. This layout was also used in other notable Alfa Romeo models like the Alfetta GT/GTV and the later Alfa 6.
