The special “30 Years 911” model was the all-wheel-drive “Carrera 4” variant of the 964 with the wide coupe body of the Turbo model. However, the voluminous rear spoiler was dropped in favour of a more harmonious and elegant shape. What remained was the automatically extending rear spoiler analogous to the standard models. Basically, the model was only available in three paint finishes. Viola metallic was the exclusive colour for the German market. Most of the special models were finished in this colour. In addition, Amethyst Metallic and Polar Silver Metallic were available as standard colours. Externally, the special model is recognizable by two badges on the parcel shelf. One of them bears the engraved limitation number of the respective vehicle and on the engine cover is the lettering “911 30 Jahre” (“911 30th anniversary”). Inside, there was leather upholstery and the dials of the instruments were in the special Rubicon Gray colour.
The 3.6-liter boxer engine produces 184 kW (250 hp) at 6100 rpm.
