The Porsche 930 Turbo and Turbo Carrera 3.0-litre (1975–1977)
Porsche introduced the first production turbocharged 911. Although called the 930 Turbo (930 being its internal type number) , the body shape incorporated wide wheel-arches to accommodate the wide tires, and a large rear spoiler often known as a whale tail on the early cars (modified from the original 1974 IROC design). They were initially fitted with a 3.0-litre engine 260 PS (190 kW; 260 hp) and four-speed gearbox.
