Audi has made an announcement of a certain progress in reducing suspension spring weight. At the moment the springs are made of steel, not only the ones of Audi, but also the springs of most manufacturers. This will change in the near future after the German automaker announced new springs that will make their debut in a “medium/large model” in late 2014 and which will be made of GFRP (Glass Fiber Reinforced Polymer), polymer reinforced with glass fibers.
These new springs are colored green and weigh 40% less than the steel ones. Moreover, the GFRP springs will not corrode and are not affected by chemicals, which means that their life span will be long.
Audi has developed these new springs, in collaboration with an Italian company, whose name is not known. It is still not known which model will be equipped first with these springs but the timing is suggesting that the 2015 Audi A7/S7 may be the one.
