What is the difference between CVT continuously variable transmission and 7-speed dual-clutch transmission?
2 Answers
CVT continuously variable transmission and 7-speed dual-clutch transmission (DCT) mainly have the following differences: 1. CVT provides a smoother and more stable driving experience and is more fuel-efficient; DCT excels in power performance, featuring fast gear shifting and quick acceleration. 2. CVT continues to be popular in the small car market and is suitable for daily use; while DCT is more suitable for high-performance models, often used in luxury cars or supercars, such as Porsche's PDK dual-clutch transmission. 3. 75% of professionals predict that DCT has a better future prospect than CVT in the medium to short term, with DCT expected to dominate the market due to its excellent performance.
There's quite a difference between these two transmissions. The CVT offers exceptionally smooth driving without any noticeable gear shift jerks, making it particularly comfortable for city traffic congestion. It also delivers stable fuel consumption, making it ideal for school runs or daily commutes. However, its downside is that during sudden acceleration, the engine noise increases with higher RPMs, and the push-back feeling isn't very pronounced. The 7-speed dual-clutch transmission shifts incredibly fast, providing exhilarating acceleration and seamless power delivery when overtaking on highways. But its mechanical structure is complex, and it can exhibit slight jerks during low-gear shifts in traffic jams. Having driven a dual-clutch car for two years, I've found it fuel-efficient on long trips but indeed more expensive to maintain. For everyday driving, I think the CVT is more worry-free.
