The Porsche 911 Carrera 4 was a variant of the Porsche 964 that was introduced in 1989. The 964 Carrera 4 was the first four wheel drive offering for the 911, built in coupe, cabriolet, and Targa body styles. These sports cars were powered by Porsche's M64 engine, which was a 3.6L flat six that generated 247hp. Power from this engine was sent to the rear wheels through a Getrag 'G50' 5 speed manual transmission. In addition to the Coupe, Cabriolet, and Targa body styles, the 964 Carrera 4 also featured other notable variants such as the Widebody and Lightweight. By the end of 964 Porsche 911 Carrera 4 production in 1994, a total of 20,395 examples had been built.
