Why does the Audi Q5L use a 7-speed wet dual-clutch transmission?
2 Answers
Audi Q5L uses a 7-speed wet dual-clutch transmission because: The working condition of the wet dual-clutch is better. Introduction to dry dual-clutch transmission: The clutch has poor thermal degradation, and the clutch is prone to overheating. If these changes cannot be well recognized by the computer, it will lead to a loss of electronic control accuracy. This can result in power interruption, shaking, or a sudden surge of power. Introduction to wet dual-clutch transmission: It is wet-type, immersed in oil, so the heat dissipation of the clutch is better, making the clutch wear and thermal degradation superior to that of the dry type. Moreover, the clutch temperature can be estimated through the oil temperature sensor, greatly improving control accuracy. Therefore, the problematic transmissions from Volkswagen are mostly the 7-speed dry dual-clutch type. Hence, the 6-speed dual-clutch transmission has better durability.
Speaking from my experience driving the Audi Q5L, this SUV opts for a 7-speed wet dual-clutch transmission primarily to enhance the driving experience. The dual-clutch gearbox shifts with astonishing speed, responding immediately to throttle input, delivering crisp acceleration without the lag typical of traditional automatic transmissions. The Q5L is positioned as a sporty SUV, and its wet design, combined with oil cooling, prevents overheating under high loads, ensuring smooth and jerk-free gear changes even in city traffic jams, thereby extending its lifespan. Additionally, it offers excellent fuel efficiency—quick shifts minimize energy waste, making highway driving more economical. Audi targets drivers who enjoy dynamic handling, and this transmission keeps the Q5L agile and responsive while balancing comfort and practicality, making long drives fatigue-free.
