Background

The 928 was a 2+2 hatchback coupé with a water-cooled aluminium V8 at the front and a rear-mounted transaxle, and the first Porsche road car with a V8. The doors, front wings and bonnet were aluminium, and the headlamps folded back to lie flat in the wings, remaining exposed when retracted. The rear suspension used the Weissach axle, designed to produce a small amount of toe-in under braking and cornering.

The 928 used a 4.5-litre V8 from 1978 to 1982. The 928 S arrived in the US for 1983 with 4.7 litres and moved for 1985 to a 5.0-litre engine with four valves per cylinder. The 928 S4 followed for 1987 with revised front and rear bodywork, and the 928 GT of 1989 to 1991 was offered with a five-speed manual only.

Automatic versions used gearboxes sourced from Mercedes-Benz, three-speed at first and four-speed from the 928 S. The 928 GTS, sold in the US from 1993 to 1995, had a 5.4-litre engine and wider rear wings, and was the final version. The 928 Weissach Edition of 1982 and the 928 S4 Club Sport of 1988 were also listed in the US.
