What does CVT mean in cars?

CVT stands for Continuous-Variable-Transmission in English, which means "mechanical continuously variable transmission" in Chinese, commonly referred to as the CVT transmission. The system components mainly include the driving pulley set, driven pulley set, metal belt, and hydraulic pump, among others. This type of transmission uses a belt and variable working diameter pulleys to transmit power, allowing the transmission system to achieve optimal matching with the engine's operating conditions. Advantages and disadvantages of CVT transmissions: 1. Advantages: Since there are no transmission gears like in a conventional automatic transmission, the resulting gear shift shock is eliminated, making the power output of a CVT transmission linear and very smooth in actual driving. 2. Disadvantages: Compared to traditional automatic transmissions, CVTs have not been used in cars for a long time, and there are not many cars equipped with CVTs in the domestic market, which means the maintenance cost of CVTs is relatively high.
CVT stands for Continuously Variable Transmission, which provides a smooth driving experience without any gear shift jerks, delivering acceleration as smooth as silk. The first time I drove a CVT car was a Honda Civic, and it felt particularly comfortable in city traffic jams. The engine RPM remained steady, unlike automatic transmissions that jerk during gear shifts, and it also saved a lot of fuel. However, it felt slightly weaker in acceleration when climbing long slopes, lacking the punch of traditional transmissions. Maintenance-wise, the CVT fluid needs to be replaced regularly, which is more expensive than manual transmissions, but overall durability is good—many Nissan and Toyota models use it. The principle involves adjusting the gear ratio via two conical pulleys and a steel belt, allowing continuous speed variation without fixed gears. It’s generally great for daily commutes, making long drives less tiring, though I occasionally miss the driving fun of a manual transmission. It’s recommended for beginners due to its ease of use and safety.
