🔧 Porsche Air-Cooled Flat-Six Engine
Porsche's air-cooled horizontally-opposed six-cylinder is the most celebrated sports car engine architecture in history. Ferdinand Piëch and Hans Mezger developed successively more powerful versions from the 2.0L 911 S of 1963 through the 2.7 RS, the 930 Turbo (3.0L with KKK K26), and ultimately to the 3.6L naturally aspirated units of the 993. The 911 ST 1970, Carrera RS 2.7 1973, and 930 Turbo all share the same rear-engine flat-six layout, bore centres, and crankcase architecture — a purity of concept achieved by no other manufacturer.
