Porsche 911 SC 3.0 Targa Design preview in Green

In 1978, Porsche introduced the new version of the 911, called the '911SC'. Porsche reintroduced the SC designation for the first time since the 356SC (as distinguished from the race engined 356 Carrera). There was no Carrera version of the 911SC. The "SC" stands for "Super Carrera". It featured a 3.0-litre aluminum engine with Bosch K-Jetronic fuel injection and a 5-speed 915 transmission. Originally power output was 180 PS (130 kW; 180 bhp), later 188 bhp (140 kW; 191 PS) and then in 1981 it was increased to 204 PS (150 kW; 201 bhp). The move to an aluminum engine was to regain case reliability, something missing for many years with magnesium. In 1981 a Cabriolet concept car was introduced at the Frankfurt Motor Show. The convertible body design also featured four-wheel drive, although this was dropped in the production version. The first 911 Cabriolet debuted in late 1982, as a 1983 model. This was Porsche's first cabriolet since the 356 of the mid-1960s. A total of 4,214 were sold in its introductory year, despite its premium price relative to the open-top targa.[15] Cabriolet versions of the 911 have been offered ever since.
