About the 1979 Porsche 928 S

Porsche's bold departure from the 911 formula, the 928 S represented Stuttgart's vision for a sophisticated grand tourer that could outrun anything on the autobahn. The naturally aspirated 4.7-liter V8 delivered 300 horsepower through either a five-speed manual or Mercedes-sourced automatic, propelling this aluminum-bodied coupe to 60 mph in under six seconds. Tony Lapine's timeless design featured pop-up headlights and a distinctive fastback silhouette that aged gracefully. Originally intended to replace the 911, the 928 instead carved its own niche as Porsche's flagship GT. Today, clean examples with manual transmissions command premium prices, especially early S models with their purer mechanical feel. The 928's combination of V8 soundtrack, balanced handling, and '80s exotic appeal makes it increasingly attractive to collectors seeking an alternative to air-cooled 911s.
