dq381 transmission is used in the Passat. The following is a related introduction about the transmission: 1. Main functions: Change the transmission ratio to expand the range of torque and speed changes of the driving wheels to adapt to frequently changing driving conditions, while allowing the engine to work under favorable conditions. It enables the car to reverse while maintaining the same engine rotation direction. By using neutral gear, it interrupts power transmission, allowing the engine to start, shift gears, and facilitating gear shifting or power output. 2. Working principle: A manual transmission mainly consists of gears and shafts, achieving speed and torque changes through different gear combinations; while an automatic transmission (AT) is composed of a torque converter, planetary gears, and a hydraulic control system, achieving speed and torque changes through hydraulic transmission and gear combinations.

I often enjoy researching car performance, and this DQ381 dual-clutch transmission is quite common, especially in performance-oriented models. For example, Volkswagen's Tiguan L, Passat, as well as Audi's A3 and A4L—these cars feel quick-shifting and responsive when driven. Many owners praise its strong performance on uphill climbs due to its high torque capacity and decent reliability. When I drove my friend's A4 on mountain roads before, it paired well with the EA888 engine, delivering stable performance. German cars favor this combination, making it a mainstream choice in mid-to-high-end models.

I've worked on many Volkswagen Group models during car repairs, and the DQ381 is frequently found in these vehicles. SUVs like the Audi Q3 and Q5 are equipped with it, and it's also common in hot hatches like the Golf GTI. In recent years, newer models tend to use it as a replacement for the older DQ380, mainly because it offers better heat dissipation. I remember someone in the Tharu owner's group mentioned that it shifts quite smoothly even in heavy traffic with frequent gear changes. This type of transmission is mostly used in transverse platforms.

This transmission is primarily used in brands under the Volkswagen Group. For example, some Audi models: the A3, A4, and Q5 series. In Volkswagen, it is commonly found in mainstream models like the Tiguan and Magotan. Earlier versions were also used in some Skoda vehicles. In terms of positioning, it leans towards performance-optimized choices.
