will i waste more gas driving fast or slow? or does it not matter?

Answer 1

By applying the physics rules ,,, we get the conclusion that by driving slower you save more gas even though it takes much time to reach the destiny...But the reason (in simple words) is that that when driving fast there is a increase in """ DRAG FORCE """ (air friction) & the friction from the road which causes the engine to burn mor gas then it should burn normally....thats it

Answer 2

It's not so much with the speed you cruise at-it's more "how fast you go to get to that speed." Fuel usage increases with demand (How far you push the throttle down). A driver who gently eases up to 65MPH from a dead stop will use less fuel to do so than a driver who slams the pedal to the floor to get to the same speed quicker.
Maintaining a steady cruising speed is also good for saving fuel.. (The throttle being pushed versus being held steady for a period of time).
To cite an example-I once owned a 1970 Cadillac Coupe DeVille with a 472 cubic inch big-block V8. By using the above mentioned driving practices, I was able to drive more fuel-efficiently than I can in my current smaller engined car because such was the torque produced by the supposed gas-guzzling V8-I barely had to touch the throttle to get it-and keep it moving.
Fast or slow doesn't matter. How you get there DOES.

Answer 3

Driving faster uses more gas, since you have to push on the gas pedal longer to get up to speed. You also have more wind resistance to push against. However, don't drive too slow - if the car doesn'ty shift into top gear, you will still be using too much gas. The real trick is to drive gently and smoothly - don't gas it hard, but gently get up to a relatively normal speed.

Answer 4

Stop and go driving is the biggest user of gas. Cruise control set at 55 will save you cash and gas, driving faster than 55, uses more gas, and you don't really get to your destination that much faster going 70, you still have to work your way around the slower drivers, causing more usage.

Answer 5

There was an episode of Brainiac - a show on G4TechTV - that tested this. I can't remember the answer, but if I had to guess, I think the best gas saver was driving fast. I'm not 100% sure, though, so verification is needed. If you check the G4TechTV website and go to that show's section, they may have the results from the experiment or a video clip of it or something.

Answer 6

You waste gas starting & stopping...
You use gas at a faster rate when you go faster, but then you're driving for less time. If you drive slower, you use gas at a slower rate, but it equals out because you drive longer, and therefore use the same amount.
I hope that made sense.

Answer 7

The two biggest driver behaviors that affect fuel economy are speed and acceleration. Stop-and-go driving, like in traffic jams, uses more fuel than driving at a steady speed, like on highways; and driving fast uses more fuel than driving slowly. Frequent, rapid acceleration in traffic or from a stop also saps fuel economy.

The faster you go the more wind resistance you have along the way, and also the engine has to run at a higher speed, using up more fuel.

Answer 8

It relies upon on fairly some factors. once you've a really aerodynamic automobile then the higher wind resistance at 80mph should be conquer with assistance from such issues as axle gearing, transmission equipment, engine, and so on. aspect a million: At 40mph fairly some autos will be in 2d or third equipment yet in a automobile like a Camaro with a 6spd. guide transmission it should be in sixth equipment (double overdrive) and it should be very in all probability that the engine replaced into definitely turning slower than at 40mph. aspect 2: All engines actually have powerbands it extremely is the rpm variety the position the engine will burn gasoline maximum effectively. If an engine is out of its powerband at 40mph yet operating at height performance at 80mph then it will be creating a lot more advantageous ability with a similar volume of gasoline intake. autos are designed to operate at particular speeds. the common sedan should be calibrated so it receives its magnificent gasoline mileage at fifty 5-70mph. yet a performance automobile should be calibrated to get its magnificent mpg at more advantageous speeds. From Wiki: the determination of vehicle and the way it really is pushed noticeably impacts the gasoline economic equipment. A proper gasoline dragster can devour 6 U.S. gallons (23 L) of gasoline (petrol) for 1 / 4-mile (four hundred metre) run in about 4.5 seconds, which comes out to 24 gallons in step with mile (5600 L in step with one hundred km). ok, so I in simple terms concept that replaced into thrilling! in many circumstances the slower you flow the more advantageous powerful mileage except the automobile is designed in the different case...yet accessible...certain.

Answer 9

driving slow takes more gas because it takes you longer to get where you are going and also going to like stop and go places wastes alot of gas

Answer 10

it's kinda of tough to answer. It really depends how you drive. vehicals get better milage when on the highway opposed to the city because you are cruising in a higher gear and don't reall yhave to start and stop. When you are in the city you are starting, stopping, having to accelerate harder to merge into traffics and such. Hope this helps
