Why do domestic cars mostly use dual-clutch transmissions?

[LaMary]

Domestic cars prefer to use dual-clutch transmissions primarily because China's self-developed transmissions are mainly dual-clutch types. The predominance of dual-clutch in China's independently developed transmissions is largely influenced by national policies. Classification of dual-clutch transmissions: Dual-clutch transmissions don't have the torque converter found in traditional automatic transmissions, making them a type of mechanical automatic transmission. Working principle of dual-clutch: By employing a dual multi-plate clutch design, power delivery isn't interrupted during torque transmission, which significantly reduces vehicle fuel consumption. Theoretically, this overturns the traditional notion that automatic transmissions consume more fuel than manual ones.

As someone who has done some research on the automotive market, I've noticed that domestic cars widely use dual-clutch transmissions mainly due to cost and supply chain advantages. The production threshold for dual-clutch transmissions is lower than that of automatic transmissions, allowing local manufacturers to easily handle parts production and keep costs low, which makes the overall vehicle price more affordable and attractive to buyers. Additionally, with national policies promoting energy savings and emission reductions, DCTs, known for their fast shifting and low fuel consumption, are naturally prioritized by automakers. Of course, not all domestic cars follow this approach, but the high adoption rate is a reality, and in daily driving, the acceleration response feels quite quick.

Having worked in an auto repair shop for many years and dealt with various transmissions, I've observed that domestic car manufacturers' preference for dual-clutch transmissions (DCT) is actually a result of technical balance. DCTs have a simple structure, are easy to maintain, offer high shifting efficiency, and are more fuel-efficient than traditional automatic transmissions, making them suitable for urban congested conditions. After introducing foreign technology, automakers can quickly localize production, remain flexible, and even optimize driving performance through software. The downsides are less smoothness compared to CVTs and occasional minor issues, but overall, the cost-effectiveness is good, and user feedback indicates significant improvements in driving experience.

As an average car owner, I've noticed that dual-clutch transmissions (DCT) are quite common in domestic vehicles, driven by market demand. Consumers desire the convenience of automatic transmissions and fuel efficiency, while DCTs offer quick acceleration, smooth operation, and an affordable price. Automakers follow this trend, with many new models prioritizing DCTs, supported by mature after-sales services and convenient maintenance at 4S shops. Although occasional gear-shifting jerks in traffic jams can be annoying, DCTs remain a practical and user-friendly choice overall.

As someone who frequently analyzes automotive trends, I've found that the widespread adoption of dual-clutch transmissions (DCT) in domestic vehicles hinges on policy support. Stringent national fuel consumption and emission standards make DCT's high efficiency and energy-saving features ideal for compliance, earning automakers subsidies and incentives. Additionally, rapid advancements in local R&D and a self-sufficient, controllable supply chain make cost management easier. Compared to the high costs of imported automatic transmissions (AT), DCTs offer clear advantages, though they may not match the comfort of CVTs on long drives. While not a perfect solution, DCTs align well with current conditions.
