How is the 7-speed wet dual-clutch transmission?
3 Answers
7-speed wet dual-clutch transmission can achieve the same durability as manual transmissions, with its durability primarily depending on the quality of the clutch friction plates and the gear set in the dual-clutch transmission. Essentially, a dual-clutch transmission is built upon two sets of MT transmissions, incorporating motors, sensors, and other electrical components to form a more advanced MT transmission. Below is an introduction to wet dual-clutch transmissions: 1. The most notable feature of wet dual-clutch transmissions is their smooth gear shifting. The method of alternating between two clutches for gear changes allows wet dual-clutch transmissions to achieve a level of smoothness that can even rival CVT continuously variable transmissions. 2. The structure of a wet dual-clutch transmission is akin to combining two AMT transmissions, which results in a more direct gear shifting method.
My car is equipped with a 7-speed wet dual-clutch transmission, and it’s incredibly smooth for daily driving. The gear shifts are quick and silent, almost as seamless as an automatic transmission. Even in traffic jams, there’s no jerking—just a light press on the accelerator, and the power kicks in right away. The fuel consumption is reasonable, slightly better than my previous car. However, it’s a bit heavy, which doesn’t affect handling much, though you might notice a slight delay during initial acceleration. It uses oil to cool the transmission, ensuring good heat dissipation and durability, so there’s no need to constantly worry about overheating damage. If you frequently drive in the city or on highways, it’s quite reliable, though it might react a bit slower during cold starts in winter. Overall, it offers great value for money—I think it’s a solid choice, but it’s best not to push it too hard with aggressive driving.
This 7-speed wet dual-clutch transmission is particularly thrilling in performance cars. I've driven my friend's GTI, and the gear shifts are lightning fast—from first to seventh gear in the blink of an eye, with direct and powerful power delivery. It performs exceptionally well on the track, with seamless power transitions, unlike conventional transmissions that can feel sluggish. The wet design prevents overheating and reduces long-term wear, though fuel consumption is slightly higher due to its more complex structure. For everyday driving, it offers rapid response and plenty of driving fun, though maintenance is pricier with regular oil changes required. On the downside, it can feel a bit sluggish at times during initial acceleration, and the noise level rises during hard acceleration. All in all, it's absolutely exhilarating for spirited driving, but don't expect it to be budget-friendly.
