Why doesn't Volkswagen use CVT transmissions?

Volkswagen has dual-clutch transmissions, and many models under the Volkswagen brand use small-displacement turbocharged engines, which are more suitable for pairing with dual-clutch transmissions. Below are specific introductions to different types of transmissions: 1. CVT: CVT is a continuously variable transmission, with advantages including fuel efficiency, low maintenance costs, and smooth operation. However, it offers weaker acceleration sensation and has limited capacity to handle high-torque engines. 2. AT: AT is an automatic transmission, with advantages including ease of operation and relaxed driving, as the automatic transmission selects the most appropriate gear based on vehicle speed and feedback from the onboard computer. However, maintenance costs and fuel consumption are higher. 3. DCT, DSG: Both DCT and DSG are dual-clutch transmissions. They offer fast gear shifting, high efficiency, and low fuel consumption. However, they require high production precision, resulting in higher costs, and provide relatively poorer comfort.

As a car enthusiast, I often ponder about transmissions. Volkswagen insists on using the dual-clutch DSG instead of CVT mainly because they pursue driving pleasure and power response. DSG shifts quickly and precisely, paired with Volkswagen's turbocharged engines, it feels like lightning-fast switching with explosive power. Although CVT is smooth and fuel-efficient, its acceleration feels sluggish like pulling a rubber band, which is completely inadequate for Volkswagen's sporty models like the Golf GTI. Moreover, CVT is prone to slipping and wear under high torque, and Volkswagen's engines have strong output, making CVT less durable and potentially problematic over time. Additionally, Volkswagen has invested heavily in developing DSG technology, with a mature and efficient supply chain. Switching to CVT would mean starting from scratch with high costs, which is not cost-effective. In short, Volkswagen's choice of DSG makes driving more exciting and reliable, and fans love this hardcore approach.

As drivers, we care more about the actual experience, and I think Volkswagen's avoidance of CVT is quite reasonable. I've driven some CVT models, and the start feels like floating without any sensation, while Volkswagen's DSG gives me a little kick during gear shifts, boosting confidence when overtaking. CVTs may also overheat during long uphill drives or when towing heavy loads, leading to reduced performance. Volkswagen models like the Tiguan SUV have high torque output, making CVT installation riskier and maintenance more troublesome. From a safety perspective, cars with precise gear shifts are more reliable during emergency maneuvers, and Volkswagen prioritizes the reliable and durable DSG to avoid costly repairs later. For daily use, DSG is also more hassle-free, with longer maintenance intervals and lower costs, unlike CVTs that require frequent special oil changes, which is too much hassle. So I quite agree with Volkswagen's decision—driving isn't just about commuting but also about enjoying the control.
