Is Audi's Dual-Clutch Transmission the Same as Volkswagen's?
2 Answers
Audi's dual-clutch transmission is not the same as Volkswagen's. Audi uses a longitudinally mounted dual-clutch transmission, while Volkswagen employs a transversely mounted one. The longitudinally mounted dual-clutch transmission is larger in size compared to the transversely mounted version, which makes it easier to arrange, dissipate heat, and handle higher torque—benefits afforded by the additional space. Below are the differences between longitudinally and transversely mounted dual-clutch transmissions: Different placement directions for the dual-clutch transmission: The transversely mounted dual-clutch transmission is placed horizontally, requiring the transmission to be arranged side by side in a horizontal orientation. The longitudinally mounted dual-clutch transmission is placed vertically, with the transmission positioned behind the engine. Different power output directions: The power transmission direction of the transversely mounted dual-clutch is typically perpendicular to the vehicle's forward motion. After entering the transmission, the power is usually transmitted horizontally and directly into the half-shafts. In contrast, the power transmission direction of the longitudinally mounted dual-clutch is parallel to the vehicle's direction of travel, transmitting power rearward. After entering the transmission, the power continues to be transmitted longitudinally toward the rear, typically connecting to the central driveshaft for direct rearward transmission.
Audi's dual-clutch transmission does have some connection with Volkswagen's, as they are both part of the Volkswagen Group. However, Audi's DL series, such as the DL382 used in the A4 and A5, is significantly more advanced than Volkswagen's common DQ series. The materials are better, the cooling design is more reasonable, and the tuning leans towards smoother operation. While models like the Volkswagen Golf use dry dual-clutch transmissions such as the DQ200, Audi mostly employs wet-type transmissions, which offer much better stability. Driving both Audi and Volkswagen cars, you can clearly feel that Audi has less low-speed jerkiness and slightly quicker response. Although the structures are similar, Audi's tuning and premium materials justify the higher price, delivering a more luxurious driving experience.
