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. It featured a 3.0-liter engine with Bosch K-Jetronic fuel injection and a 5-speed 915 transmission.Originally power output was 180 bhp,later 188 bhp and then in 1981 it was increased to 204 bhp. In 1981 a Cabriolet concept car was introduced at the Frankfurt Motor Show. Not only was the car a true convertible, but it 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. It proved very popular with 4,214 sold in its introductory year, despite its premium price relative to the open-top targa. Cabriolet versions of the 911 have been offered ever since.
It was during this time, that Porsche AG decided the long-term fate of the 911. In 1979 Porsche had made plans to replace the 911 with their new 928. Sales of the 911 remained so strong however, that Porsche revised its strategy and decided to inject new life into the 911 editions. 911 SC sales totaled 58,914 cars.
Peter W. Schutz (CEO Porsche AG 1981–1987) wrote:
The decision to keep the 911 in the product line occurred one afternoon in the office of Dr. Helmuth Bott de:Helmuth Bott, the Porsche operating board member responsible for all engineering and development. I noticed a chart on the wall of Professor Bott's office. It depicted the ongoing development schedules for the three primary Porsche product lines: 944, 928 and 911. Two of them stretched far into the future, but the 911 program stopped at the end of 1981. I remember rising from my chair, walking over to the chart, taking a black marker pen, and extending the 911 program bar clean off the chart. I am sure I heard a silent cheer from Professor Bott, and I knew I had done the right thing. The Porsche 911, the company icon, had been saved, and I believe the company was saved with it.
