Why are domestic cars mostly equipped with dual-clutch transmissions?
2 Answers
Domestic manufacturers prefer dual-clutch transmissions primarily due to lower technical barriers and relatively easier development. Below are introductions to dual-clutch transmissions: Dry Dual-Clutch: The clutch plates in a dry dual-clutch transmission are not immersed in transmission fluid. This type offers faster shifting speeds and higher transmission efficiency. Wet Dual-Clutch: The clutch plates in a wet dual-clutch transmission are immersed in transmission fluid. This type provides better reliability and durability, and can handle higher torque. However, wet dual-clutch transmissions have more complex structures and higher costs.
The widespread use of dual-clutch transmissions in domestic vehicles can be understood from several perspectives. First, in terms of cost control, dual-clutch transmissions are significantly cheaper than traditional automatic transmissions, allowing manufacturers to reduce overall vehicle prices and enhance competitiveness. I remember when I bought a domestic car, the salesperson emphasized this point, stating that dual-clutch systems are easy to mass-produce, benefit from a well-established local supply chain, and have shorter development cycles, helping me save on my car budget. Second, regarding technical compatibility, dual-clutch transmissions pair well with small-displacement engines, delivering high efficiency and maintaining good fuel economy whether in city traffic jams or on highways. Third, market demand drives this trend, as modern car owners prefer the convenience of automatic transmissions, and dual-clutch systems provide a smooth driving experience, especially in newer models. Fourth, policy influences play a role, as China's stringent emission standards make dual-clutch transmissions a viable solution to reduce fuel consumption and comply with regulations. Of course, not all domestic vehicles use dual-clutch transmissions; some high-end or new energy models opt for CVT or AT, but the mainstream preference leans toward dual-clutch for cost control. From my personal experience, daily driving feels fine, though prolonged traffic jams might occasionally result in slight jerking.
