Good ride performance is one of the most important key attribute of a passenger vehicle. One of the methods to achieve this is by using continuously variable transmission (CVT). This is because a CVT has the capability of providing an almost infinite ratio within its limits smoothly and continuously. The flexibility of a CVT allows the driving shaft to maintain a constant angular velocity over a range of output velocities. Currently, new developments in gear reduction and manufacturing have led to ever more robust CVTs, which in turn allow them to be applied in more diverse automotive applications. As CVT development continues, costs will be reduced further and the performance will continue to improve, which in turn make further development and application of the CVT technology desirable. This cycle of improvement will offer CVT a solid foundation in the worlds automotive infrastructure. The purpose of this paper is to provide some background and relevant information that is necessary in this study. Specifically, a brief description of CVT, advantages and their brief history are presented. This paper also evaluates the current state of CVT, investigate the technology frontline of drivetrain control and the development of CVT. The step less Transmission is able to maintain the engine running in its maximum power.
