911 1978-1983 3.0L / SC

In 1978, Porsche unveiled the updated iteration of the 911, christened the '911SC'. This marked the reintroduction of the SC moniker for the first time since the 356SC, distinct from the racing-engineered 356 Carrera. Unlike its predecessors, the 911SC did not have a Carrera variant. While contemporary Porsche literature and websites do not offer a period-specific explanation for "SC," it's now commonly interpreted as "Super Carrera." 

Under its hood was a 3.0-liter aluminum engine equipped with Bosch K-Jetronic fuel injection, paired with a 5-speed 915 transmission. Initially, it boasted 180 PS (132kW; 178hp), later upgraded to 191 PS (140kW; 188hp), and finally to 204 PS (150kW; 201hp) by 1981. The shift to an aluminum engine aimed to restore case reliability, a feature long absent due to the previous use of magnesium.

At the 1981 Frankfurt Motor Show, Porsche unveiled a Cabriolet concept, featuring a convertible body design with four-wheel drive, although this feature was omitted in the production version. The first 911 Cabriolet hit the market in late 1982 as a 1983 model, marking Porsche's return to the cabriolet market since the mid-1960s 356. Despite its premium pricing compared to the open-top targa, 4,214 units were sold in its inaugural year. Ever since, Cabriolet versions of the 911 have remained a staple offering.
