A ribbed belt, also known as a serpentine belt, is a continuous belt with longitudinal grooves running along its length. These grooves enable the belt to grip the pulleys more effectively, reducing slippage and improving power transfer between the engine and various auxiliary components. In modern vehicles, including the W211, ribbed belts are used to drive multiple accessories such as the alternator, water pump, power steering pump, and air conditioning compressor.

The production process of poly V belts also impacts their pricing. Advanced manufacturing techniques can lead to higher costs due to the sophisticated machinery and technology involved. For instance, belts produced with precision molding and cutting-edge quality control processes may offer better performance and longevity than those made with traditional methods. As a result, manufacturers that invest in innovation and technology often have higher-priced products.
