  • Continuously variable transmissionWikipedia

    A continuously variable transmission (CVT) is an automatic transmission that can change seamlessly through a continuous range of gear ratios.This contrasts with other transmissions that provide a limited number of gear ratios in fixed steps. The flexibility of a CVT with suitable control may allow the engine to operate at a constant RPM while the vehicle moves at varying speeds.
