2018 Audi A8 Body Structure

Body Structure

Luxury automakers have a history using different materials in their vehicles. The body structure of the Audi A8 combines four different lightweight design materials – a mix of aluminum, steel, magnesium and carbon fiber-reinforced polymer (CFRP). A high-strength combination of hot-formed steel components make up the occupant cell, which comprises the lower section of the front bulkhead, the side sills, the B-pillars and the front section of the roof line. Some of these sheet metal blanks are manufactured in varying thicknesses by means of tailoring technologies – they’re tailor-made in other words – and others also undergo partial heat treatment. That reduces weight and increases the strength, especially in areas of the vehicle that are particularly critical for safety.




Fasteners

The auto industry uses different fasteners and methods to attach metals together. Below is a picture of all the different types used by Audi in the new A8 body structure.
