Is it true the faster you drive the more gas you burn?

Question

Is it true the faster you drive the more gas you burn?

Answer 1

Duh! Yup.

Answer 2

yes is true. if you drive faster over the speed limit. your car will burn more gas.  even if you car cylinder is from 1.5 to 3.5 cylinder you will still lose gas because you are driving at the highest speed that's why when new car or automotive bring out their new cars. they testes at 60mph or 65 mph. so from that they estimate how MPH your car burn in the highway and at city they tested at 35mph. so the automotive industry recommended you to drive at those mile so you can save gas and save the environment. let me tell you it is not but if you drive 35mph on city or 65 of highway because you save your life which mean you are more aware of other driver who are driving fast, also you save other lives of other people and also save globe warming. I work at CA, POWAY and I live Here in Del Cerro, SD, CA and from my work to home is 16 mile if i took a short cut or 18 mile if i took the normal way and I drive a 2006 Honda CRV EXL With 4/4 which estimate 22 on the city and 29 highway and I use to drive faster at 80 mph every time I go to work and when I come back home and by gas prices going up to $3. I learned a valuable lesson that i don't way to speed all my money on gas. so i drive 35 on city and 65mph on highway and now i fill my tank two time in three weeks which better than four time in three weeks and it doesn't better me when people are passing me. I'm saving on gas, my money and also my life and so the others. SO IF YOU DRIVE FAST YOU WILL BURN MORE GAS.

Answer 3

Sure.  Remember the Shell (or was it Mobil?) Oil Mileage Driving Competitions in the 1940's and '50's?  The drivers did everything possible to avoid actually driving their vehicles at any speed over idling; they actually drove less than ten miles per hour.  To be fair, they did produce some awesome mileage figures for the cars they drove - close to 100 mpg in some cases, as I recall.  

They also sacrificed everything not essential to operating the car - air conditioning, power anything, radios were deleted, spare tires and jacks were removed and the tires were inflated to ridiculously high figures.  In addition, they used neutral whenever they could in order to reduce drag, especially when descending hills.  Of course the figures were not easily duplicated by the average drivers, but they were attained.

Thanks for asking.  Good luck!

Answer 4

Yes and no.  Most cars are engineered to run most efficiently around 45 mph.  Faster speeds are less fuel efficient but so are slower speeds.  It's all about gearing, power/torque ratios, etc...

Answer 5

It depends on your vehicle.

For older vehicles (2000 and older) yes, usually anything over 60, you're using more fuel than if you were driving 55.

But, newer cars are being designed to get the same fuel economy at 70 that they'll get at 55. For example, my 2001 Ford Escape gets the same fuel mileage at 75 that it does at 55.

Answer 6

Come on, use commen sense.

Answer 7

True to a point . Driving at 80 eats gas. But putting along in town at 30 is even worse. Especially when you go from one red light to the next.

Answer 8

Yes.... engine at 6000 rpm's uses more gas than at 2000 rpm's....

Answer 9

yes,55 and over

Answer 10

Sort of...it's not technically the speed you are traveling but the speed at which your engine is rotating.  

For example, watch the tachometer on a car as you speed up.  It will go up and then down as the car shifts into other gears.  The reason why you shift is to save gas and keep the engine running at a point where there is least wear.  The slower the engine runs the less gas you usually use.  Except when you're idling.  Usually, you should keep the gage below 3000 rpm when being gas-conscious.  This ususally provides a decent gradualy accelleration and conserves gas at the same time.

My mileage goes down dramatically when i'm going over 80 compared to about 75mpg.  I usually get 40 to a gallon pure highway (25 city) on my 92 saturn sl1.  (I averaged 38mpg from ohio to cali through the rockies and all, a year ago.)

Answer 11

YESSSSSSSSSSSSSSSSSSSSSSSSSS.

Answer 12

that all depends on how the vehicle is set up but in most all cases it takes more gas to go fast

Answer 13

When you go fast, you literally use more gas. Fuel is needed to power your car, and the more power needed by the engine the more fuel is needed.

I hope that I helped you.
