THE USE OF ALUMINUM IN THE PORSCHE 928

Of the 1420 kg total body weight of the Porsche 928, 266 kg are aluminum, distributed throughout the engine, clutch and manual gear box, chassis and suspension, body, and electrical assemblies. Die-cast, chill-cast, rolled, and extruded aluminum components are employed. The engine is of all-aluminum which provides a favorable power-to-weight ratio. The upper and lower parts of the crankcase are made of different types of aluminum. There are 35 aluminum alloy castings in the engine. Clutch and transmission housings are highly stressed and are made of a cast alloy. The unitized body includes aluminum fenders, doors, and hood together weighing 33 kg. Use of aluminum helps reduce vehicle weight and increase stiffness.
