car mileage info image

Driving at high speeds decreases mileage, but so does constant acceleration and braking.... so how does driving at higher speeds on the highway give you better mileage according to EPA mileage info?
Thanks, Project.
Ok.... so, I live in L.A., and our highways are usually filled with traffic, so the advantage of higher highway miles probably wouldn't apply to me, right?
Answer
It takes less fuel to keep your car going at a constant velocity than it does to get it moving from a stop. All the stop and go you do in city driving uses more fuel than a constant speed on the highway. Idling and accelerating are the two biggest drains on fuel economy, and you do them often in city traffic. By keeping the throttle relatively still and not flucuating much on the highway, you are delivering a constant even fuel supply to the engine, instead of large amounts of fuel in bursts during stop and go traffic. Now, just because you get better mileage on the highway does not mean the faster you go the better economy you get. There is a point of diminishing returns where the vehicle's aerodynamics will start to bring down fuel economy. But, driving at a constant speed is what gives you the fuel economy advantage over city driving. Hope this helps.

What do I need to know when searching for a car?

I have my permit and i'm about to get my license. I need to get a car though but I don't know what to look for it one. What is car mileage, what features should be required, etc. Just please let me know anything I should to find a nice car. I want a small, normal car. So if you have any suggestions for one, too, then please let me know. Thank you!
Answer
There's a lot to know! Go to the library and read the most recent Consumer Reports magazine auto issue. In there they list everything you need to know about which used cars are good and which aren't.
As far as actually buying the car, learn how dealers try to rip people off before you go to one. Just google for "how to buy a used car" and read the info that shows up.
As far as which cars are the best, Toyota and Honda are the most reliable used cars pretty much, although lots of other ones are good too.
