At the 53rd Turin Motor Show of November 1971 Fiat introduced the 128 Coupé, also called 128 Sport, a 2-door, 4-seat coupé based on a shortened 128 chassis. It was produced until 1975, but in latter years sales were dropping off considerably in favor of the mid-engined X1/9. Since Fiat had to pay a commission to Bertone for every X1/9, it was decided to provide some internal competition in the form of the updated hatchback coupé 128 3P. "3P" stands for "Tre Porte", or "Three Doors" in Italian. The 128 3P used the existing design back to the B-pillar, with some detail modifications to the grille and headlights.
