Would accelerate too fast or speeding too fast like 70 mph will use more gas than low acc and low speed?

Question

So is this mean that the more revolution you accelerate, the more fuel will be used

Answer 1

Class, please quiet down. It is a proven fact that the faster you drive, the more fuel you consume. A lot of this has to do with wind resistance, but also that it simply takes more fuel to run the engine faster. There is a point at which your car will get optimum mileage. Every car is different, but for many cars it's somewhere around 40 miles per hour. At this point, most cars have shifted into high gear, reducing engine RPM to a low level, and wind resistance isn't much of a factor, so the car reaches sort of an "equilibrium" of sorts, the most efficient combination of speed, RPM, wind resistance, gear ratios, the car's weight, and other factors. As far as heavy acceleration, the more you step on the gas, the more gas you're going to use. It has to do with engine vacuum, among other things. Your car will accelerate all by itself to about 15 miles per hour just by idling, which uses very little fuel, but if you really open it up and jump to 15 miles per hour, you will use more fuel getting to that speed. However, you will reach that speed quicker. The most economical way to drive is to accelerate gently, stay off the brakes by using the car's natural ability to slow down by itself, don't speed up and slow down a lot, and don't drive too fast.

Answer 2

yes, this is proven by the physics of air resistance. This is because air resistance increases as the square of speed, so the faster your go, the more fuel you need to overcome the net effect of air resistance on the car.

Answer 3

the higher your RPM's, the higher your fuel consumption.

Answer 4

YES!
