What is the transmission model of the Tayron 380 R-Line 4WD?

The transmission model of the Tayron 380 R-Line 4WD is the DQ381 7-speed wet dual-clutch transmission. This transmission performs significantly better than the 7-speed dry dual-clutch in terms of performance and effectively reduces gearshift shock. Precautions for using the 7-speed wet dual-clutch transmission: When the vehicle is in forward or reverse gear, the clutch system remains engaged. If the vehicle is stationary, the clutch is in a state of sliding friction, which increases the temperature of the clutch plates and accelerates wear. When the vehicle is idling in D or R gear, the engine increases throttle opening and fuel supply to maintain idle operation, leading to higher fuel consumption. Precautions for using the 4WD system: Due to the high friction between tires and dry pavement, high-speed cornering can be very dangerous. The inner wheels may experience excessive rotation and friction, causing the tires to lift off the ground and the vehicle body to rise via the axles and suspension. Combined with centrifugal force, this can easily cause the vehicle to roll over in the opposite direction of the turn. Therefore, on dry paved roads, it is best to avoid using limited-slip differentials, whether on the front or rear axle. Similarly, it is also advisable to avoid using part-time 4WD systems.
I've studied the 4WD system of the Tayron 380 R-Line, which uses the DQ381 wet dual-clutch transmission. This 7-speed gearbox has an excellent reputation within the Volkswagen Group, capable of handling up to 420N·m of torque. During my last test drive, I clearly felt the exceptionally smooth gear shifts with almost no noticeable jerkiness. It's said that this transmission uses a new-generation hydraulic system with improved cooling performance. However, when driving such dual-clutch vehicles, it's advisable to switch to manual mode during prolonged traffic jams to avoid frequent partial engagement, which can extend its service life. For regular maintenance and transmission fluid changes, it's recommended to use the factory-specified G052529A2 fluid.
