What is the difference between a CVT and an automatic transmission?

[Ellen]

There is no difference between a CVT and an automatic transmission, as both belong to the category of automatic transmissions. In an automatic transmission, each gear is controlled by a set of clutch plates to achieve the shifting function. The structure of a CVT is simpler than that of a traditional transmission, with a more compact size. It does not have the multiple gear pairs of a manual transmission or the complex planetary gear sets of an automatic transmission. Instead, it primarily relies on two sets of variable pulleys to achieve continuously variable speed ratios. An automatic transmission simply changes the shifting direction of a manual transmission into a linear motion, enabling automatic movement in terms of direction, but it still shifts gears step by step from low to high speeds. In a CVT, the incremental and decremental gear indicators are no longer visible externally; only directional differences such as forward and reverse can be seen. A CVT provides smoother performance than an automatic transmission during high-speed overtaking and high-speed cornering.

I've driven many cars and found the biggest difference between CVT and automatic transmissions lies in their structures. Automatic transmissions have fixed gear ratios, like 6-speed or 8-speed, and you can feel slight jerks during gear shifts, like climbing stairs step by step. CVT has no gears, instead using a steel belt and cone pulleys to continuously adjust the speed ratio, making acceleration as smooth as gliding on ice. This creates significant differences in driving experience: in CVT cars, RPM rises steadily with less noise, making driving more effortless; automatics have shift points that offer more driving fun, but occasional jerks can affect comfort. Additionally, CVTs are generally more fuel-efficient as the engine always operates at optimal efficiency, while automatics waste a bit of energy during gear changes. When choosing, consider your needs - for daily commuting, I'd recommend CVT for its smoothness and efficiency.

I usually drive that small car to commute, and the biggest impression CVT gives me is its extreme smoothness. When stepping on the accelerator, the engine sound rises monotonously without any gear shift shock. In comparison, automatic transmissions make you distinctly feel each gear shift during starts and accelerations, like a light tap on the back. This smoothness makes commuting much more comfortable, especially in traffic jams where you don't have to frequently deal with jerks, relaxing a lot. But some people think CVT is too bland, lacking excitement, and the gear shift sensation of automatic transmissions actually provides driving rhythm. In the long run, CVT has a slight advantage in fuel consumption, with more intelligent engine speed regulation, but maintenance might be more complicated. After trying different models, I prefer the gentle feel of CVT, which is particularly suitable for city roads.

I highly value fuel efficiency and environmental friendliness, and CVT (Continuously Variable Transmission) has obvious advantages in these aspects. By enabling continuous gear shifting, it avoids the gaps between gear changes, keeping the engine consistently within the most efficient RPM range, unlike automatic transmissions that briefly waste fuel during gear shifts. In real-world driving, especially in stop-and-go city traffic, CVT can reduce fuel consumption by around 10%, saving a significant amount of money over time. Although automatic transmissions also feature efficient designs, CVT offers more precise control over power delivery. This structural difference directly impacts vehicle operating costs and environmental impact, making CVT-equipped models a worthwhile choice in my opinion.

I frequently repair various transmissions. The key differences between CVT and automatic transmissions lie in reliability and maintenance costs. CVTs feature intricate structures relying on steel belt drives, which may wear over prolonged use, making repairs labor-intensive and expensive. Automatic transmissions are relatively simpler with robust gear sets - often just requiring clutch plate replacements, with abundant and affordable spare parts. In daily driving, CVTs provide smoother operation, but major failures often incur hefty repair bills. Automatics may occasionally exhibit gear shifts but prove more durable long-term. Before purchasing, evaluate your budget: automatics are safer bets for frequent long-distance or heavy-load driving, while CVTs suit urban commutes better.
