IDENTIFYING THE SC CHANGES Through model years

MY 1977: SC announced as Coupe and Targa models. 2,994cc flat six as 3.0 Carrera, but refined for greater efficiency. No quarterlights. Sport had Turbo tea tray, while standard UK interiors had pinstripe cloth seats with leather option. Heating and ventilation improved by a third electric fan and minor instruments now had plain backgrounds. Standard SC wheels were 15-inch ATS five-spoke and arches received wider flares.

MY 1979: Chromed window surrounds disappear

MY 1980: Upgrade to 188bhp. SC inherits 380mm Turbo threespoke steering wheel. Tighter weave carpeting.

MY 1981: Now tuned to run on 98 RON with compression ratio raised to 9.8:1 and delivering 204bhp at 5,900rpm and 265Nm at 4,300rpm.

915 gearbox given higher fifth. Thicker torsion bars fitted and Sport version given own slimmer whaletail, as well as Bilstein dampers and 16-inch Fuchs. ‘Pasha’ cloth added to options and now extended to rear cabin. Zinc body coating (already standard) warranty extended to seven years. Leatherette (vinyl) upholstery standard for most SC factory production: UK cars almost always delivered with higher spec, including sunroof.

MY 1982: Cabriolet launched; takes over 40 per cent of 911 sales in 1982/3.

MY 1984: Carrera 3.2 supersedes SC.
