Whilst CVTs have many Advantages, they also have some possible disadvantages. For example, some drivers may well see that The shortage of distinct gear shifts may make it tricky to judge how the car is undertaking, and others could discover the motor sound for being far more recognizable than with a standard transmission.

If that Appears somewhat perplexing, the matter to remember is always that a CVT gearbox doesn’t need to soar in between gears like a daily automatic would from 2nd to 3rd equipment, or fifth to fourth, such as. Instead, the pulleys in a CVT will regularly alter from The instant you established off, each of the way as many as motorway speeds.
