Audi Space Frame winner of the EuroCarBody AWARD
Audi is the winner of the EuroCarBody AWARD from the Automotive Circle International for the innovative body concept of the Audi TT, Audi Space Frame (ASF).
In the new TT, Audi has further developed ASF technology, and added high-strength steel to the material mix. Aluminium accounts for 69 percent of the total body weight. Steel components are used at the rear of the floor assembly. The doors and boot lid are also made of steel. This provides an optimum distribution of axle loads, making for superior handling.
The TT body-in-white weighs 206 kg, of which 140 kg is aluminium and 66 kg is steel; as an all-steel construction it would be 48 percent heavier. The aluminium components of the ASF comprise 63 kg of sheet, 45 kg of castings and 32 kg of extruded sections.
The new form of ASF developed for the Audi TT has qualities that are perfect for a sports car. The static torsional stiffness of the Coupé is roughly 50 percent higher that that of its predecessor; on the Roadster the increase is an incredible 128 percent.
