Porsche 928 S4 1991 - 164 807 KM

At the dawn of the 1970s, Porsche wanted to break away from its image as a single-model brand. And despite the resounding success of the 911, some of the managers at Zuffenhausen tried to push the emblematic coupe towards the exit. Indeed, the layout of its backpack flat-six was considered outdated and without a future. A statement that seems comical in retrospect, but which was the subject of fierce debate at the time.

This desire to diversify led to the development of new bodies and engines, giving rise to the PMA (Porsche front-engine) models such as the 944 and 928, the latter embodying Porsche's desire to position a car in the GT 2+2 sports car market. It began its development phase in 1971 and went into production 6 years later, in 1977. Equipped with a front-mounted 4.5-liter V8, its avant-garde design is the antithesis of that of the 911. And like all PMAs, it didn't go down too well with Porsche enthusiasts, who regarded the new architecture as sacrilegious. But no matter, this was not the car's core target market. Largely aimed at the American public, its V8 and automatic gearbox quickly made it popular across the Atlantic.

Surprisingly, the 928 enjoyed a longevity of 18 years, with a succession of increasingly powerful and accomplished versions. In 1986, the Porsche 928 was redesigned and marketed as the S4, an upgraded version of the S2 with a 320 hp 5.0 L V8 engine. The front and rear fascias were redesigned to improve aerodynamics, and a rear spoiler was added to improve downforce at high speeds.
