What is the difference between car CVT and automatic transmission?

[StRonan]

The differences between car CVT and automatic transmission are: 1. Different gears: CVT only has forward and reverse gears; automatic transmission has parking gear, reverse gear, forward gear, etc. 2. Different structures: CVT has a simple structure and smaller size; automatic transmission has a relatively more complex structure and larger size. 3. Different transmission chains: CVT uses a steel transmission chain; automatic transmission uses a gear set transmission chain. CVT refers to a transmission system that can continuously obtain any transmission ratio within the speed range, achieving optimal matching between the transmission system and engine conditions. Automatic transmission means the vehicle automatically selects the appropriate gear based on driving speed and traffic conditions.

I used to drive a car with a CVT (Continuously Variable Transmission), and the acceleration felt incredibly smooth, like gliding on ice without any jerks, with the RPM staying stable, making it very fuel-efficient. However, the CVT has a simple structure, relying on belts and pulleys for transmission without fixed gears, so there's no shifting sensation, which some people find boring. Automatic transmissions are different—they use planetary gear sets, producing slight vibrations during gear shifts, yet offering a sense of driving engagement, more akin to the traditional cars old-school drivers love. CVTs are excellent for city commuting—quiet and smooth—and they handle long trips just fine. Automatic transmissions, on the other hand, are more durable on mountain roads or when towing heavy loads. A heads-up: CVT belts may wear out faster, so maintenance requires extra care; automatics cost a bit more in fuel but are generally reliable. In short, if efficiency and fuel economy are your priorities, go for a CVT. If you crave driving excitement, choose an automatic. But modern cars are evolving, and the gap between the two is narrowing.

From my experience, the most noticeable difference between CVT and automatic transmission is the acceleration style. CVT provides continuous variation, delivering a smooth and uninterrupted drive like flowing water. Automatic transmissions have fixed gears, causing RPM fluctuations during acceleration and a slight jerk when shifting, which feels like changing rhythms. CVTs use a belt system, making them lightweight and fuel-efficient, while automatics rely on gears and clutches, offering sturdier reliability. In terms of cost, CVTs have lower maintenance expenses, but belt replacements can be pricey; automatics have more repair parts available and are easier to service. I’ve noticed that CVTs may lack power on steep slopes, with belts prone to slipping, whereas automatics are more stable. So, CVTs are cost-effective for daily commuting, but automatics are worth considering for frequent suburban or highway driving.

CVT acceleration is super smooth, with no gear shift shock, driving feels like riding an elevator going up. Automatic transmissions have noticeable gear shifts, with RPMs rising and falling. In principle, CVTs use pulleys and belts to continuously adjust the gear ratio; automatic transmissions are gear systems that switch between fixed gear ratios. CVTs are more fuel-efficient because the RPM remains constant; automatic transmissions respond faster and perform better at high speeds and uphill. When buying a car, it is recommended that housewives who focus on fuel efficiency choose CVTs, while those who love handling choose automatic transmissions. Both are reliable, depending on budget and needs.
