The Porsche 964, manufactured and sold between 1989 and 1994, featured significant styling revisions over previous versions of the 911. It was the first generation of 911 to be offered with Porsche's optional Tiptronic automatic transmission as well as all-wheel drive.

The 964 was available in both all-wheel drive equipped "Carrera 4" models and rear-wheel drive "Carrera 2" variants, offered as a coupe, Targa, or Cabriolet. It featured a new naturally-aspirated engine called the M64, with a flat-6 displacement of 3.6 liters. The suspension was substantially revised, and power steering and ABS brakes were added for the first time. The exterior bumpers and fog lamps were integrated into the car for better aerodynamics, and a new electric rear spoiler was introduced.
