Why are domestic cars mostly equipped with dual-clutch transmissions?
2 Answers
Domestic cars predominantly use dual-clutch transmissions for the following reasons: Dual-clutch transmissions offer the fastest gear shifting speed, perfectly unleashing engine power while maintaining relatively low fuel consumption and manufacturing costs. Below are the classifications of dual-clutch transmissions: 1. Wet dual-clutch: A wet dual-clutch consists of two multi-plate clutches (one large and one small) coaxially assembled together, both housed in a sealed oil cavity filled with hydraulic fluid. This design provides superior modulation capability and excellent thermal stability, enabling transmission of higher torque. 2. Dry dual-clutch: Developed based on the 6-speed DQ250 wet dual-clutch technology, the dry version simplifies the associated hydraulic systems.
I've always driven domestic cars and noticed that dual-clutch transmissions are quite common mainly due to their cost-effectiveness. Dual-clutch transmissions are significantly cheaper to manufacture and maintain compared to traditional automatic transmissions. Domestic brands prioritize them to attract budget-conscious buyers. Additionally, the wide availability of technology sources, such as technical licensing from partners like Volkswagen, allows many automakers to quickly adopt this technology, reducing costs while also improving shift speed. This aligns with the price-sensitive characteristics of the Chinese market, and younger consumers particularly enjoy its responsive feel. However, potential issues shouldn’t be overlooked, such as low-speed jerkiness or durability challenges. But overall, its affordability and widespread adoption make it a mainstream choice. For daily driving, it’s indeed a balanced solution.
