What are the advantages and disadvantages of coasting?

[Michelle]

Advantages and disadvantages of coasting are introduced as follows: 1. Disadvantages: The inertia of the vehicle causes the tires to rotate, and the clutch and transmission drag the engine to rotate. These loads will cause certain mechanical wear and consumption. 2. Advantages: Fuel saving. Generally, fuel injection vehicles stop supplying fuel to the engine when the speed is at 1200 rpm without stepping on the accelerator pedal (throttle pedal). Another advantage is the better feeling of brake distance control. When braking with gears engaged, it is easier to control the braking force. However, professional tests have shown that emergency braking in neutral and emergency braking with gears engaged have the same braking distance, but braking with gears engaged requires less effort.
