Also known as the 993, the third-generation Porsche 911 arrived in 1993 as a replacement for the 964 version. The 993 was quite different from its predecessor, with only 20 percent of its parts carried over from the previous model. Also, the naturally aspirated 3.8-liter and the turbo 3.6-liter flat-six engines were completely new. Built until 1998, the 993 was not just the last air-cooled 911, but also the last of the hand-built 911s. Besides the usual Carrera and Turbo models, the 993-gen 911 also spawned RS, Speedster, Targa, and GT2 versions.
