The W211 PK ribbed belt is designed with multiple grooves along its length. This ribbed or serpentine design increases the surface area and improves grip on the pulleys it contacts. The belt is typically constructed from high-quality rubber, which may be reinforced with various materials to enhance durability and resistance to wear, heat, and environmental factors. As a result, these belts can efficiently transmit power to multiple components, including the alternator, air conditioning compressor, power steering pump, and water pump.

A variable belt drive is a mechanical device that transmits power between shafts using a belt and pulley system that can be adjusted to change the tension and/or the diameter of the pulleys. This variability allows for different gear ratios, enabling machines to operate at various speeds and loads. Unlike fixed belt drives, which offer a single gear ratio, variable belt drives provide a more adaptable solution, making them suitable for applications where variable speed and torque are necessary.
