A CVT, or continuously variable transmission, 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:
- Smooth, stepless gear changes
- Improved fuel efficiency by containing RPMs, or engine speed
Disadvantages of CVT over automatic transmissions include:
- Less responsive acceleration
- Can feel disconnected from the driving experience
CVTs are becoming more common in modern vehicles and are seen as a way to create better fuel economy. They have been around since the late 1980s and are now a regular fixture in modern vehicles.
