Pulley-based CVT
A continuously variable transmission (CVT) is an automatic transmission that can change through a continuous range of gear ratios, typically resulting in better fuel economy in gasoline applications. 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 angular velocity while the vehicle moves at varying speeds. Thus, CVT has a simpler structure, longer internal component lifespan in theory, and potentially greater durability. Compared to traditional or standard automatic transmissions, it offers lower fuel consumption and greater environmental friendliness.
