What is the difference between CVT and dual-clutch transmission?
2 Answers
CVT and dual-clutch transmissions differ in their nature and characteristics. Below is a detailed introduction to the differences between the two: 1. Nature: The 7-speed dual-clutch transmission is a dry clutch, developed based on 6-speed technology, which simplifies the related hydraulic system. It is generally paired with small-displacement engines. CVT refers to a continuously variable transmission, which does not have specific gears and operates similarly to an automatic transmission, but the ratio changes differ from the gear-shifting process of an automatic transmission. 2. Characteristics: The 7-speed dual-clutch transmission is more prone to overheating, so its thermal resistance is inferior to that of a wet clutch, resulting in a relatively lower torque capacity. The power output of a CVT transmission is linear, providing a very smooth driving experience. However, the steel belt used in the transmission has limited load-bearing capacity.
After driving a manual for ten years, I finally figured out the nuances of automatics. A CVT feels like riding an electric scooter—smooth and jerk-free throughout. It uses two conical pulleys and a steel belt to vary ratios without fixed gears, delivering linear acceleration like climbing a gentle slope. Dual-clutch transmissions (DCT) are different beasts: they operate like manual-transmission cousins, with two clutches alternating shifts. Gear changes are lightning-fast, perfect for driving enthusiasts who love crisp downshifts for overtaking. However, DCTs may overheat and shudder in stop-and-go traffic, while CVTs can’t handle high-torque thrashing. For daily comfort and fuel efficiency, choose a CVT; if you crave driving excitement, go DCT—it’s all about priorities: practicality or adrenaline.
