World's first rear axle transmission crossbeam made of plastic in the S-Class from Mercedes-Benz
The world's first plastic transmission crossbeam in the rear axle subframe has been developed by ContiTech Vibration Control and BASF for the S-Class from Mercedes-Benz. It is made from the engineering plastic Ultramid® A3WG10 CR, a specialty polyamide from BASF which is particularly reinforced and optimized to withstand high mechanical loads. Compared to the previous beam made from die-cast aluminum, this highly durable component offers a weight saving of 25%.
