A number of steel bodies from Audi, from the A1 (Combined fuel consumption in l/100 km: 7.1 – 3.8; Combined CO₂-emissions in g/km: 162 – 99)** to the A7 Sportback, comprise significant proportions of high- and ultra high-strength steels of different strength classes. The best of these are the hot-shaped steels, which stand out due to their extreme tensile strength and the resulting weight-savings potential.

Audi is taking the development of the steel body a step further – to the Multimaterial Space Frame, which combines components of aluminum, steel and fiber-reinforced polymers (FRP) with one another. The future of this new “ultra” technology has already begun with the bodies of the A7 Sportback and the new A6 (Combined fuel consumption in l/100 km: 9.6 – 4.4; Combined CO₂-emissions in g/km: 225 – 114)**.
