The All-Aluminum Auto Body - A Study Based on the Porsche 928 830094

An all-aluminum body in a unitized construction of a sportscar has been developed as a prototype. Design features, forming, welding, and surface treatment have been studied as well as the results of the test trials. A weight-saving of 47 % compared to an all-steel body was achieved with good characteristics of static and dynamic stiffness, operational reliability, passive safety properties, corrosion resistance, noise level, and repairability.
