β¦ Synopsis
A new belt-drive continuously variable transmission (CVT) has been developed and installed in a 2-liter class vehicle for the "rst time in the world. This paper describes the technical features of this high torque capacity transmission, the need for a torque converter, the importance of electronic control and the driving modes achieved. This new CVT provides better driving performance and fuel economy than current CVTs and 4-speed automatic transmissions.
