A '''continuously variable transmission''' ('''CVT''') is an automated [[Transmission (mechanical device)|transmission]] that can change through a continuous range of [[gear ratio]]s, typically resulting in better fuel economy in gasoline applications.<ref> {{cite web|url=https://www.caranddriver.com/research/a31517125/cvt-transmission-vs-automatic-quick-guide/#|title= CVT Transmission vs. Automatic: Quick Guide |access-date=January 19, 2025|publisher=Car and Driver}}</ref> 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, and greater durability. Compared to traditional automatic transmissions, it offers lower fuel consumption and is more environmentally friendly.<ref> {{cite web|url=https://www.ml-vehicle.com/info/advantages-and-disadvantages-of-continuously-v-97706558.html|title= Advantages and Disadvantages of Continuously Variable Transmission (CVT) |access-date=April 24, 2025|publisher=ML truck}}</ref><ref> {{cite web|url=https://www.coastwiderwc.com.au/the-environmental-impact-of-automatic-and-cvt-transmissions/|title= THE ENVIRONMENTAL IMPACT OF AUTOMATIC AND CVT TRANSMISSIONS |access-date=April 24, 2025|publisher=Coastwide}}</ref>

CVTs are used in cars, tractors, [[Side-by-side (vehicle)|side-by-side]]s, motor scooters, [[snowmobile]]s, bicycles, and [[Heavy equipment|earthmoving equipment]]. The most common type of CVT uses two [[pulley]]s connected by a [[Belt (mechanical)|belt]] or [[Chain drive|chain]]; however, several other designs have also been used at times.
