Difference between DQ500 and DQ381?
2 Answers
dq500 can withstand higher torque than dq381. The maximum torque capacity of DQ381 is 380NM, while DQ500 can withstand up to 600N*M of torque. dq500 is the most high-end transmission in the Volkswagen Group. Here is some extended information about transmissions: 1. Introduction: A transmission is a mechanism used to change the speed and torque from the engine, capable of fixing or changing the gear ratio between the output shaft and the input shaft, also known as a gearbox. 2. Composition: Transmission: It consists of a gear transmission mechanism and a control mechanism. Most transmission mechanisms use ordinary gear transmission, while some use planetary gear transmission.
I think the difference between these two transmissions mainly lies in their application scope. The DQ500 is the dual-clutch transmission with higher torque capacity in the Volkswagen family, capable of handling up to 600 Nm of torque output. Performance cars like the Audi RS3 use it. On the other hand, the DQ381 is mainly installed in 380TSI or high-power four-wheel-drive models, with a maximum torque capacity of around 420 Nm. Additionally, the DQ381 is actually a junior version of the DQ500, with improvements in lightweight internal components, making it more fuel-efficient. Recently, when replacing the clutch plates for a friend's Touareg X, I noticed that the DQ500's hydraulic valve body is larger in size, and its repair kit is about 30% more expensive.
