For volkswagen this car brand, presumably everyone is already familiar with it, but if it is using which automatic transmission, many people may only know that it is used with a dual-clutch transmission, and then some specific is dry and wet two, of course, this is no problem, but not too specific, Volkswagen is currently commonly used automatic transmission has five kinds, the following specific to understand:
The first is the 6AT gearbox codenamed AQ160, this gearbox is mainly mounted on some low-end models, and the previous 1.6L, the current 1.5L engine matches, such as Langyi, Bora's 1.5L automatic transmission model is used this gearbox, of course, don't look at the AT to think that it is more high-end, the actual maximum withstand torque is only 160 Nm, only suitable for matching with small displacement self-priming engines, but the quality and compliance are not bad, and the performance of power response and other aspects is very general.
The second is a seven-speed dry dual-clutch transmission code-named DQ200, which is mainly used with 1.2T and 1.4T engines, such as Langyi, Bora, Sagittarius, Golf, Maiteng, Audi A3, Q2L and other models, which can withstand up to 250 Nm of torque. The advantage is that the transmission efficiency is high, the power is good and the fuel consumption is low, and the disadvantage is that low-speed driving is prone to setbacks, and the reliability is also general under the premise of more congested road conditions.
The third is the seven-speed wet dual-clutch code-named DQ381, which is actually an upgraded version of the DQ380, which mainly matches volkswagen's 2.0T engine and can withstand a maximum torque of 420 Nm. The 2.0T version of the Passat, Maiten, Tiguan L and other models uses this gearbox. Although there is a slight decrease in transmission efficiency compared to the dry double clutch, its better heat dissipation makes the stability of the entire gearbox much better.
The fourth is the seven-speed wet dual-clutch transmission codenamed DQ500, which is currently the best gearbox on the Volkswagen MQB platform, such as the lens, the new Tuang has been used, the overall performance, tuning, shift logic and other aspects of the performance are particularly outstanding, the disadvantage is that the cost is relatively high, only used on high-end models.
The fifth model uses relatively less, is the code name DQ400e hybrid gearbox, in fact, this is also a dual clutch, and the traditional dual clutch transmission is different from it also has a motor involved in the work, thus achieving hybrid drive, such as passat, Golf hybrid models, the use of this gearbox. Although the application time is not long, but its technology is relatively mature, between the engine and the motor are mechanical transmission, reliability is better, the disadvantage is that when the pure electric and hybrid mode is switched, there will be a slight power interruption, affecting the quality of driving.
