Why do domestic cars mostly use dual-clutch transmissions?
2 Answers
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.
