Which saves more gas–driving faster and getting there quicker, or slower and getting there slower?

40-45 MPH!
FACT for most cars.
Any slower more gas- Any faster more gas- is used.
If you go to slow you throw away all the torque. If you go to fast you fight a wall of air.

the slower you drive and the slower you accelerate, the more gas you save.

pushing the gas really quick at stop lights sucks all your gas up, so it’s better just to go slow.

your burning up more gas if you drive there faster and your wasting gas if you drive slower so either way you would just waste gas. the only way to save gas is to go to a closer place.

the faster you go the harder your engine works thus using more gas. driving the speed limit (about 50-55) is the best.

neither..
just buy a really good car,
with good gas mileage!

An average of the two. If you drive between 50-60 mph it will give you the highest gas mileage. Also take it easy on the brakes, it is true that it takes gas to brake.

mmm… I’ve heard the speed that uses the minimum amount of gas is 55 mph.

fuel economy decreases dramatically when you drive over 60 in newer cars, even lower speed in older cars. That means, as much as it sucks, driving the speed limit will actually save you money.

slower saves gas, less rpm’s less gas

well if you slowly speed up to your highspeed then it dowsn’t burn that much more gas. you gotta be smooth you know

It’s all about your acceleration. Don’t mash the pedal when you’re at a stop light. Accelerate to your desired speed as slowly as possible. Also keep your tires properly inflated, get the junk and extra weight out of your trunk and get a Speedy Rewards card and/or Speedway credit card. I got mad Speedy points.

Go from 40-50 MPH. It is not to fast, (Going fast burns gas fast) but not to slow (Going slow will waste gas without going far.

Driving over 60 mph loses you 5 gallons per hour (I’m using averages here). So, if you don’t go over 2000 rpm, you’re at optimum distance/fuel consumption.

Remember that whenever you accelerate, you’re losing gas because the engine can’t burn as much as you’re putting into it. Keeping a constant speed is the best solution.

Driving so you don’t have to press hard on the gas or the brake. Keeping it flat and even is the key–regardless of the speed.

going slower will be better for the gas.

depends on the car and if you have cruise control, type of gas… but if you push the gas petal too much you are wasting gas.

driving slower saves up more gas

gas mileage generally decreases above 55mph. Driving slower than that may increase your gas mileage as long as you can maintain that speed and it’s not stop and go.

As long as your engine is running, it will be using gas. If you’re going faster, you’ll be feeding more gas to the engine, but you’ll be able to coast for longer. If you’re driving slower, your engine will be running for a longer period of time, using more gas in the long run. It really depends on the kind of trip you’re taking. If there will be lots of red lights you don’t want to be driving fast just to have to stop, because then you’re unnecessarily using more gas than you need to, but if you’re on a long stretch of highway, you can drive faster to save gas because you’ll be able to cruise down hills and such.

OK here is the answer…..Faster and getting there quicker. I just bought a new car and it shows my miles per gallon. If I drive slow I get less miles per gallon. When im flying on the freeway it gets way more miles per gallon than if im just doing the speed limit.

Studies show it is slower. Probably slower than you want to go.

for most cars, the “sweet spot” on the speedometer is in the range of 40-60 mph.

That last line comes from this summary in this article about the complicated physics of it.

Depends on the vehicle. gear ratios, aerodynamics, weight.etc, etc,. I had an 84 Corvette that got the best milage at 62 mph. Ya just have to try differant speeds to cruise at
