As automobiles move toward hybrid and electric technologies, the role of rubber ribbed belts may evolve. Although many hybrid models still rely on traditional internal combustion engines, there is a growing trend toward the utilization of electric drive systems, which may eventually lead to a decreased reliance on ribbed belts. Nevertheless, until fully electric vehicles become more predominant, rubber ribbed belts will continue to be a fundamental component in the engine systems of traditional vehicles.

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.
