벨트 장력을 유지하기 위해 유압을 따로 적용하며 이로 인해 효율성이 떨어진다. 엔진의 최적 회전수 영역에서는 무단변속이 이 단점을 상쇄하지만, 최고 단수 영역에서 엔진의 회전수가 계속 올라가는 경우 자동변속기 대비 효율이 떨어진다.
Numerous operate using a v-formed friction belt jogging amongst two pulleys that could vary their diameter at the same time, earning one particular bigger as the opposite becomes more compact to take care of stress around the belt.
