Porsche 911 SC
1978 saw a new 911 introduced, known as the Porsche 911 SC. Overall, it was meant to be more refined, more driveable, and more dependable, all with the aim of attracting new buyers to the brand. The SC, which stands for "Super Carrera" was destined to be the last of the model 911 line as the all new front-engine mounted V-8 Model 928 was waiting in the wings to take over as the flagship for the 1979 model year. The SC was built around the 1974 Carrera 3.0 Turbo engine except with no turbos and it was also the first Porsche truly designed for the worldwide audience.
The model 911SC offered American buyers an attractive 15 bhp bump over it's predecessor the model 911 S. Porsche sought to make the SC a 'world' car by fitting every model for every market with an exhaust emission air pump. The emissions regulator created a 20bhp loss for the Europeans when the SC replaced their 200bhp model Carrera 2.7. Porsche made compensation for the loss of power by advancing the timing of the camshafts by a mere six degrees, allowing it to pull surprisingly strong from low rpm.
Over its life, the SC got updates almost every year. Power was increased for the 1981 year model, now with 204 hp. In late 1981, a Cabriolet concept car was introduced at the Frankfurt Motor Show. This was the introduction of Porsche's first true convertible. The Cabriolet was made available to the public in late 1982 as a 1983 model and proved to be wildly popular despite a premium price tag, selling out more than a year in advance. There were basically 3 special editions of the model 911SC.
