The Porsche 993 is the fourth generation of the Porsche 911 model sports car manufactured and sold between January 1994 and early 1998, replacing the 964. Its discontinuation marked the end of air-cooled 911 models.

The Porsche 911 is a two-door 2+2 high performance rear-engined sports car introduced in September 1964 by Porsche AG of Stuttgart, Germany. It has a rear-mounted flat-six engine and originally a torsion bar suspension. The car has been continuously enhanced through the years but the basic concept has remained unchanged. The engines were air-cooled until the introduction of the 996 series in 1998.
