For the 1975 model year, Porsche introduced the first production turbocharged 911’s. Only 284 examples built for the inaugural year in 1975 Although called the 930 Turbo (930 being its internal type number) in Europe, it was marketed as the 930 Turbo Carrera in North America. 1976 Turbo Carrera, Porsche only produced 530 U.S.-spec Type 930s built for that model year. The body shape incorporated exaggerated fender flares and a large rear deck spoiler announced that the Turbo Carrera was no ordinary 911. The Turbo’s performance matched its looks; the turbocharged three-liter air-cooled engine delivered its power through a strengthened four-speed manual gearbox, and many were equipped with an optional limited-slip differential.
Porsche 911 Turbo was revised in 1977 when the German manufacturer unveiled an upgraded version of the car. The new car had adjusted suspensions and new air deflectors installed in front of the rear wheels as well as a couple of new elements meant to improve the aerodynamics. The engine was upgraded too, the 3.3-liter being now able to produce a maximum power of 300 hp with a 0 to 100 km/h acceleration in 5.3 seconds. There would be only 727 North American-specification Turbos built and sold for model year 1977.
In 1978 Porsche revised the 930 with a 3.3-litre turbocharged engine with intercooler that produced 300 PS (220 kW; 300 hp). The increased engine size reduced the turbo lag. The intercooler required a "tea-tray" tail design for the whale tail. Porsche branded the car as the Porsche Turbo
