The 911 SC effectively replaced the 911 S and was one of Porsche's first models that was meant for the international market. It was sold as a cheaper alternative to the 911 Turbo. The SC used an unblown version the 930 Turbo unit that offered 180 to 200 bhp depending on model year. Options included the rear whale tail, front chin spoiler, Bilstein dampers, 16 inch wheels with Pirelli P7 tires and sports seats. Sometimes dealers lumped these options together to create their own sport package. It was available as a Coupe and Targa from 1978 - 1983, while the Cabriolet version was only available in 1983.
Finally, in 1982 the model 911 SP 'Ferry Porsche' was introduced as a special edition to celebrate 50 years of Porsche. This special edition was finished in Meteor metallic paint with burgundy leather interior and a 'Ferry Porsche' signature on the headrests. Only 200 of these now-classic special cars were built (130 Coupes and 70 Targas). The 911 SC “Jubilee” or “Ferry Porsche” is the first “limited series” sold in Europe.
In 1980, a true limited edition model 911SC was produced for the American market. The 'Weissach' edition was a standard SC with special paint. It was built in 1980 to honor the Porsche Motorsport team working in Weissach Germany. 468 units were made and half were painted Metallic Black, the other half in Platinum Metallic. The interiors were wrapped in Doric Grey leather with burgundy piping. Additional body and mechanical specs included whale tail spoiler, Bilstein dampers and Fuchs wheels.
The 'Martini' edition of 1978, was identifiable by a set of side stripes similar to those that appeared on the 1976 British Motor Show 911 Turbo which was clad with the stripes to celebrate victories in the World Manufacturers Championship and the World Sports Car Championship, as well as the fourth consecutive racing season with sponsors Martini & Rossi. The stripes were so popular that Porsche quickly made them an option available to any owner as a factory or retro fit.
