There are constant dilemmas when it comes to driving a car in terms of the fuel efficiency and how to properly take care of your car. Though we have seen many videos on certain problems where people elaborated for hours and hours on these dilemmas and problems, up until now no one has ever made a video on one problem that concerns the fuel efficiency on whether it is better, coasting or engine braking while going down from a hill. The man from the YouTube channel Engineering Explained takes us through an in-depth elaboration and pointing out to facts connected to this matter.
The rotations per minute and the speed are presented on the bottom left of the screen so you could better follow the situation and explanation. There is the first situation in which you go down from a hill from point A to point B. In this situation if you coast your car i.e. drive in neutral it would mean that the engine has to use some fuel in order to keep itself going, whereas on the other hand, if you engine brake, the engine keeps running in a straight line and it does not need to use an fuel at all.
Moreover you keep the speed limited to a certain point which basically means that you are going to have a much safer ride and you are not going to use the brakes as much.
What do you think, what is better for fuel efficiency? Coasting or engine braking?
