Why are domestic cars mostly equipped with dual-clutch transmissions?

[EmersynRose]

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.
