A Continuously Variable Transmission (CVT) is an automated transmission that can change through a continuous range of gear ratios, unlike 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. CVTs are used in cars, tractors, side-by-sides, motor scooters, snowmobiles, bicycles, and earthmoving equipment. The most common type of CVT uses two pulleys connected by a belt or chain, but several other designs have also been used at times.
Advantages of CVT over automatic transmissions include smoother driving experience, stepless gear changes, and improved fuel efficiency. CVTs are always automatically adjusting to your driving, providing smooth gear changes. They help improve fuel efficiency by containing RPMs, or engine speed. According to Carfax, one of the most significant advantages of having a CVT is that they are often more fuel-efficient than a regular automatic.
CVTs are technically considered an automatic transmission because the driver doesn’t have to manually operate a clutch pedal or shift between gears.
