A CVT, or continuously variable transmission, is a type of automatic transmission that provides seamless acceleration without the distinct gear shifts found in traditional transmissions. It uses a system of pulleys and a belt to adjust the gear ratio continuously, allowing the engine to operate at its most efficient RPM for various speeds. This technology enhances fuel efficiency and provides a smoother driving experience. Many modern vehicles, especially hybrids and smaller cars, utilize CVT systems to optimize performance and reduce emissions, making them a popular choice among manufacturers aiming for better environmental standards.
