ELI5:What is a CVT transmission? Is it really that bad despite it being the "latest" transmission?
gpt
CVT or continuously variable transmission essentially removes the slight jerking movement of the car while shifting gears, known as shift shock. It works by dynamically adjusting a belt, which corresponds to a gear in a regular automatic. Imagine the CVT like a bicycle’s gear system. It’s made up of a pulley system, with cones at each pulley, all connected by a chain belt. These cones move closer together or further apart to increase or decrease the diameter at which the belt operates. These ratios are always changing in order to find the perfect combination for speed, fuel efficiency or both.

CVT has many advantages and drawbacks. It’s good on fuel economy, gives a relatively smooth ride, and is versatile enough for daily driving. CVT is much better at travelling uphill because where traditional automatics can struggle, a CVT can seamlessly provide power without shifting. Even-speed hill driving can prove to be a tough endeavour for novice manual transmission drivers.

But, car enthusiasts will say that it’s nowhere near as fun or engaging as a dual clutch automatic or manual transmission. CVT also tends to make quite a racket when accelerating hard, and isn't very good at towing in some cars. .
