This article delves into the specifics of this formidable race car, exploring its unique features and the context of its creation. Readers will gain insight into what made the K4 a significant, albeit limited, entry in Porsche's racing lineage.






















The Porsche 935 is a racing car developed from the 911 Turbo (930) for Group 5 motorsport. It was introduced in 1976 as Porsche's factory entry for the World Championship for Makes, and quickly became a dominant force in endurance racing. The car was known for its distinctive flat-nose design and wide bodywork, which evolved significantly throughout its production.
Mechanically, the 935 was powered by a turbocharged flat-six engine, with displacement varying across different iterations. Early models featured a 2.85-liter unit, later expanding to 3.2 liters, producing significant horsepower figures. The chassis was heavily modified from the production 911, incorporating advanced aerodynamics and suspension components designed for track performance.
The 935 achieved widespread success, securing numerous victories including the 24 Hours of Le Mans in 1979 and multiple World Championship titles. Its impact on motorsport history is substantial, making it a highly sought-after model among collectors of vintage racing cars and Porsche enthusiasts.
However, I always ask myself lif these closed rims do not impact the cooling of the brakes? Thx for sharing, Dirk
