Continuously variable automatic transmissions with belt-type variator are gaining increasing significance, most especially in front-transverse installations. Their favorable fuel consumption levels, increased comfort and wider ratio ranges in comparison with multi-ratio automatic transmissions make them ideal components for the modern driveline.
The continuously variable ratio adjustment provides significant advantages. However from a technical development standpoint, increasing the (design-based) mechanical efficiency and optimizing co-ordination with the engine represent the greatest challenge and a significant potential for further development.
