The 928 models were powered by a water-cooled V8 engine in which the cylinders were at a 90° angle. The displacement of the engine increased from the initially 4.5 liters to 5.4 liters. Power was transmitted through the transaxle principle. To improve aerodynamics, starting with the 928 S model (model year 1979), the models were equipped with a front and rear spoiler.
The rear axle of the 928 was a completely new development. What made this double wishbone suspension, also known as the Weissach axle, unique was its stabilizing toe-in effect. This worked more or less like passive rear wheel steering, which contributed significantly to the Gran Turismo’s active safety.
928 (model years 1978 – 1982)
The rounded rear end with no rear spoiler was an unmistakable and distinctive feature of the 928. Unlike later successors, this model had no front or rear spoiler. The 928’s 4.5-liter engine produced 240 horsepower.
