What is the real reputation of Volkswagen's dry dual-clutch transmission?
1 Answers
Volkswagen's 7-speed dry dual-clutch transmission has a polarized reputation in the market. Explanation of Volkswagen's 7-speed dry dual-clutch transmission: As the name suggests, Volkswagen's 7-speed dry dual-clutch transmission has some internal structures without lubrication oil, aiming to save the cost of a few liters of transmission oil. The transmission features two separate oil chambers in its oil circuit design, using less than half the oil volume of an automatic transmission. This special construction allows it to withstand higher torque output while maintaining low maintenance costs. However, the disadvantages of Volkswagen's 7-speed dry dual-clutch transmission are also evident. In traffic congestion, due to insufficient lubrication oil, the heat generated by the transmission cannot dissipate in time, leading to sluggish gear shifting and strong jerking sensations. Therefore, it is crucial to be cautious when choosing Volkswagen's 7-speed dry dual-clutch transmission. Considerations when choosing Volkswagen's dual-clutch transmission: Overall, dual-clutch transmissions offer smooth and fast gear shifting with good fuel economy. It should be noted that the failure rate of dry dual-clutch transmissions is higher than that of wet dual-clutch transmissions. In the past, Volkswagen had a very high market share in the United States, but due to the oil crisis leading to rising fuel prices, Japanese cars with CVT transmissions, which excel in smoothness and fuel economy, gained favor among American consumers.
