Currently, most cars are equipped with automatic transmissions, among which CVT (Continuously Variable Transmission) and AT (Automatic Transmission) are the mainstream choices. CVT achieves stepless speed change through a steel belt and cone pulleys, with the advantages of smooth acceleration and outstanding fuel economy, making it particularly suitable for urban commuting. For example, many household cars of Japanese brands such as Toyota and Honda are equipped with this type of transmission. AT transmissions, relying on torque converter and planetary gear set technology, offer stable and reliable gear shifting and are commonly found in mid-to-high-end models, such as SUVs like the Proton X70. In addition, Dual-Clutch Transmission (DCT) has gradually become popular in sports cars due to its fast shifting speed, such as some Volkswagen models. Although the proportion of manual transmissions has decreased, they are still favored by driving enthusiasts and are mostly seen in economy cars or performance car versions. Transmission technology is continuously optimized; for example, CVT steel belts can withstand higher torque after material upgrades, and E-CVT for hybrid models may also become a new trend in the future.
