2010 Platform
2010 Platform - Audi A6 First to use a new aluminum Steel Space Frame (ASF II). This could be the German OEM prototype referenced for a 2010 platform in NR and Investor presentation. Talks about steel/foam reinforcements and weight savings of up to 300Kg.
"Despite the lightly evolved design, the new A6 under the skin is just the opposite with a new construction method resulting in 50% body shell weight loss and 50% increased rigidity. Car Online spoke with Audi chief strategist and reports the A6 will be the first model to introduce the new body structure which incorporates both steel and aluminum materials. "
"Similar to the ASF (Aluminum Space Frame) body construction seen in the low volume R8, TT and A8 models, the new A6 will receive this hybrid body of steel and aluminum, dubbed ASF II, consisting of an all aluminum passenger cell with steel/foam reinforcements."
