Why are domestic cars mostly equipped with dual-clutch transmissions?
4 Answers
Domestic manufacturers prefer dual-clutch transmissions primarily due to fewer technical barriers and relatively easier development. 1. Dry-type: The clutch plates in dry dual-clutch transmissions are not immersed in transmission fluid. Dry dual-clutch transmissions offer faster gear shifts and higher transmission efficiency. 2. Wet-type: The clutch plates in wet dual-clutch transmissions are immersed in transmission fluid. Wet dual-clutch transmissions provide better reliability and durability, and can handle higher torque. However, wet dual-clutch transmissions have more complex structures and higher costs.
To be honest, after years of working in auto repair shops, I've noticed that domestic car manufacturers favor dual-clutch transmissions (DCT) for several key reasons. Cost is a major factor—DCTs have a simpler structure than traditional automatics and use cheaper materials, making them ideal for domestic brands to cut production costs. They offer fast gear shifts and high efficiency, delivering a sporty feel that appeals to younger drivers. Fuel efficiency is another advantage; models like the Geely Emgrand or Haval H6 use DCTs, with owners reporting savings of about half a liter per 100 kilometers. However, drawbacks exist, such as jerky performance in city traffic and the need for regular hydraulic system checks to prevent wear. My advice is to test-drive different models before buying—don’t just follow the trend. While electric vehicle transmissions are gaining ground, DCTs will likely remain popular in traditional fuel-powered cars for years to come.
I drive a domestic car with a dual-clutch transmission myself, and the quick starts are impressive, plus the fuel efficiency is genuinely great. Why are manufacturers so keen on using them? I think it's market-driven: consumers want affordability without sacrificing driving pleasure, and dual-clutch transmissions offer fast gear shifts and low fuel consumption, perfectly meeting these demands. They're more exciting than CVTs and cheaper than ATs, helping domestic brands boost competitiveness. For example, models like the Changan CS series or Roewe are actively promoting them—they feel exhilarating on highways, though there might be occasional minor jerks at low speeds. Not all domestic cars use them, though; some hybrids are shifting to other types. When buying a car, considering road conditions and brand reputation is crucial—safety always comes first.
The evolution of car transmissions from manual to automatic has given rise to dual-clutch technology as a product of technological revolution. Originating from racetrack designs, it is highly efficient, fuel-saving, and offers seamless gear shifts. Its adoption by domestic car manufacturers reflects progress, as its structural threshold is not high, enabling rapid R&D and production by local firms. Models from brands like Geely and Great Wall have seen noticeable sales growth after incorporating it. However, issues exist, such as potential durability reduction over long-term use. Future trends may lean toward hybrid and electric drives, but dual-clutch transmissions in gasoline cars still dominate.
