Audi To Introduce Polymer Suspension Springs On New Models

Audi is preparing to introduce new lightweight polymer springs that are designed to improve suspension adjustment and efficiency.

Set to debut in an executive class model before the end of the year, the fibre glass-reinforced polymer (GFRP) springs are apparently 40 per cent lighter than their traditional steel counterparts

Except the Corvette's are leaf springs -- quite different

I'm not sure what a suspension bolt has to do with Polymer vs Steel? For a modern suspension, there is no real "bolt" that holds the springs on. If the spring comes off you will have either lost your entire trailing arm or strut, in which case the Polymer vs Steel debate will be the least of your worries.

I love to see innovations like this. Weight reductions in unsprung weight really improve handling. Although the gains in probably be off-set by the added rotational mass of the current "big wheels" trend.

Reviews - Get back on your Tricycle and go play. Once again you showed you're NOT an auto enthusiast or guru regarding cars (Corvettes specifically). I have a little red wagon you can get some experience with.

GM was the innovator who first implemented fiber class into a production cars suspension, Audi is just implementing it into modern suspension. BMW will be addressing the reduction in unsprung mass with carbon fiber wheels.

All this talk of polymer this carbon fiber that radically increases cost, but the benefits are miniscule.

Weight reduction, improved gas mileage and stronger materials usually equal large benefits . . .
