A continuously variable transmission (CVT) is a transmission which can change steplessly through an infinite number of effective gear ratios between maximum and minimum values. The flexibility of a CVT allows the driving shaft to maintain a constant angular velocity over a range of output velocities.
CVTs can compensate for changing vehicle speeds, allowing the
engine speed to remain at its level of peak efficiency. This
improves fuel economy and by effect, exhaust emissions.
CVTs operate smoothly since there are no gear changes which
cause sudden jerks.
