Does it matter how hard you break in regards to gas usage?

Question

Does braking harder make you use more gas? Or should you start breaking slowly at a distance? And going faster means more gas? Thank you.

Answer 1

Yes this all does effect the gas usuage.
The harder u brake, u more power needed to make the brakes work, thus more power taken from the engine, thus more gas as the engine runs on it. Not to mention, that ur brake paddings would finish quicker.
Going faster doesnt really mean u use more gas. It depends on how u reach top speeds. IF u, let say, floor the pedal from the start, then u use alot of gas. But if u steady increase ur speed, like making sure ur RPM doesnt go above 3 on the dail, then u are using it efficiently. Also, going above about 70-80 km/h, u are using more gas to keep it at higher speeds than this. So accelerate slowly and keep it average high speeds.

Answer 2

How much fuel you use depends on a lot of factors. You use more fuel when accelerating as the engine is working harder. So if you do lots of heavy braking and accelerating you will use more fuel than gentle braking and acceleration. You do use more fuel the faster you go as the engine is working at higher revs. The harder the engine is working the more fuel it uses. You generally use less fuel if you travel at a constant speed and avoid stop/start traffic.

Answer 3

YEP.
Braking harder means you were traveling to fast to slow properly. this also heats up and prematurely wears the brake.
It is a fact that driving fast does burn more gas, but a bigger drinker is actually the quick acceleration from stops.

Answer 4

Yes it uses more gas and it's hard on your brakes and your motor as well.

Answer 5

If you have to brake hard then you are a lousy driver who does not know how to drive or look after your car properly

Answer 6

You mean 'brake' and not 'break' right?
