Is the Roewe RX5 transmission dry or wet?
1 Answers
Roewe RX5 1.5T models with automatic transmission are equipped with a 7-speed dry dual-clutch transmission; the 2.0T models are paired with a 6-speed wet dual-clutch transmission. The differences between wet and dry transmissions are as follows: 1. A dry clutch transmits power through direct contact of metal plates, providing more direct power transmission. When the metal plates are pressed together, the transmission ratio increases, resulting in more immediate and noticeable effects. In contrast, a wet clutch uses oil as an intermediary, requiring the driving plate to accelerate, increasing the centrifugal force of the oil, and then accelerating the driven plate. This additional step means the response speed is slightly slower. 2. Structurally, wet clutches are more complex, which leads to higher energy loss. As a result, wet dual-clutch transmissions have lower transmission efficiency, consuming more engine power. All else being equal, wet transmissions tend to have higher fuel consumption than dry ones. 3. The metal friction plates in dry clutches cannot withstand high torque. Excessive stress can easily damage the friction plates, limiting dry clutches to small-displacement, low-torque vehicles. Wet clutches, however, have no such limitations. They can handle everything from 1.5L displacement, 200N˙m family cars to 6.0L displacement, over 1000N˙m supercars.
