The Audi Space frame is a high-strength aluminium frame structure into which all panels are integrated so that they also perform a load-bearing function.
In connection with these high-strength aluminium panels, the aluminium body is noted for its exceptional rigidity, resulting in high crash protection, yet also for its substantially lower weight.
The benefits of aluminium in the Audi Space frame are reflected not only in the low weight and the high rigidity of the body, but also in a level of design freedom for cast parts and complex profiles that's unattainable with steel panels.
Advantages include greater safety, increased performance, improved handling, lower fuel consumption, ease of repair and attractive insurance premiums.
