One thing people need to keep in mind is that a CVT in a car works entirely different than a CVT in a tractor - the two have nothing in common except for the ability to provide infinitely variable ratios. The automotive ones are basically a belt drive between variable diameter sheaves. However, a tractor CVT works by combining parallel-path mechanical and hydrostatic drives together with the drive ratio being determined by how fast the hydro portion is rotating. Being that the bulk of the power is till being transferred through the mechanical system the efficiency is on par with a powershift which is much greater than what a pure hydro would provide. The overall system is actually much less complex than a powershift transmission with fewer components.
