The speed corresponding to the car gear！！#driving #skills #tips #knowledge #fpy

When I want to change from 3rd to 4th gear, the best situation is when the speed reaches 70, because when it reaches 60 and I change, the car decelerates and I feel this beautifully and it bothers me a lot. I tried this with several other cars and it is the same, of course my car has high performance and this could be the reason. I wanted to know why it is like this and where is the problem?
