Why doesn't Volkswagen use CVT transmissions?
2 Answers
Volkswagen has dual-clutch transmissions, and many of its models are equipped with small-displacement turbocharged engines, which are more suitable for pairing with dual-clutch transmissions. Below are specific introductions to different types of transmissions: CVT: CVT is a continuously variable transmission. Its advantages include fuel efficiency, low maintenance costs, and smooth operation, but it has weaker acceleration thrust and limited capacity for high-torque engines. AT: AT is an automatic transmission. Its advantages include ease of operation and relaxed driving, as the automatic transmission selects the most suitable gear based on vehicle speed and feedback from the onboard computer. However, it has higher maintenance costs and fuel consumption. DCT, DSG: DCT and DSG are both dual-clutch transmissions. They offer fast gear shifts, high efficiency, and low fuel consumption. However, they require high production precision, resulting in higher costs, and provide less comfort.
As a tech enthusiast, I believe the main reason Volkswagen avoids CVT transmissions is engine compatibility. Volkswagen engines tend to prioritize high torque output, especially in diesel and high-performance gasoline versions. The steel belt design of CVTs is prone to slipping under high loads, affecting acceleration response and durability. In contrast, DSG dual-clutch transmissions offer faster shifts, higher efficiency, and can handle greater torque, perfectly aligning with Volkswagen’s powertrain philosophy. I still remember test-driving a Golf GTI—the DSG’s rapid gear changes felt exhilarating, while some CVT models felt sluggish when climbing hills, delivering a poor experience. Cost isn’t the core issue, since Nissan and Toyota CVTs are also affordable, but Volkswagen prioritizes reliability and technical consistency to avoid potential failure risks, which is crucial for everyday drivers.
