The vehicle in detail

The introduction of the 911 SC in 1978 represented a concerted effort by Porsche to appeal to a wider market than had hitherto been the case with earlier cars. Zuffenhausen’s move to use the fully galvanised G-series chassis from 1976 onwards had presented an ideal opportunity to produce a 911 for all seasons; a tantalising prospect made all-the-more feasible by the introduction of the new 3.0-litre type-930 engine.

Featuring a stiffer die-cast aluminium crankcase in place of the 2.7-litre magnesium unit, the engine had been developed for the nascent 930 Turbo and featured Bosch K Jetronic electronic fuel injection rather than the earlier unit’s mechanical equivalent. Although this resulted in a modest reduction in peak power, both flexibility and torque were improved, rendering the new unit ideally suited to everyday road use at variable speeds.

The 911 SC was an immediate success, with more than 60,000 cars constructed over its six-year lifespan. In 1980—with a third of total SC production delivered already—Porsche took the decision to acknowledge the achievements of their motorsport department by producing a limited edition run of just 468 911 SC “Weissach” cars. Internally designated as with the “M439” option code, these cars were intended exclusively for the US market and were ostensibly standard in mechanical specification. Exterior finish choice was divided equally between either Metallic Black or Platinum Metallic, with all cars trimmed in Doric Grey leather and burgundy piping. Additionally, “Weissach” cars would be identifiable by their Platinum Metallic finish 15-inch Fuchs wheels, chin spoiler and modified Turbo-style rear spoiler.
This wonderfully original example was completed at the Porsche factory on 13 June 1980, duly finished in Platinum Metallic and fitted with a limited-slip differential, cruise control, alarm system and front fog lights. Displaying an enviably low odometer reading of just 79,001 kilometres, it was acquired by the vendor in April 2016.

Impeccably preserved in its original factory specification—and, crucially, retaining its matching-numbers engine—this remains a highly exclusive variant of arguably the most important air-cooled 911 in Porsche’s history. These factors, in conjunction with 911 SC’s legendary usability and the Weissach’s huge “kerb appeal”, mean that more compelling cases for 911 ownership have seldom been put forward.
