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.

A sports car is a car designed with an emphasis on dynamic performance, such as handling, acceleration, top speed, the thrill of driving, and racing capability. Sports cars originated in Europe in early 1910s and are currently produced by many manufacturers around the world.
