Audi announced that they will start utilizing glass fiber reinforced polymer springs (GFRP) that will be 40-percent lighter, stronger and more resistant to corrosion caused by chemicals such as wheel cleaners.

The automaker says each GFRP spring weighs 3.5 lbs. while a standard steel spring weighs as much as 6 lbs.  It may not look like much, but reducing 9.7 lbs. in the chassis is crucial and provides more driving precision while lessening vibration according to Board Member for Technical Development at Audi Dr. Ulrich Hackenberg.

The look and diameters of the spring also differs quite a bit than a traditional spring. It’s green in color, has a thicker fiber than steel, has a slightly bigger diameter and has a lower number of coils.

Where fuel economy is a key seller nowadays and weight saving is also a must, these new springs developed by Audi is something to behold for the future of not only factory-made cars but maybe also in the aftermarket scene.
