City mileage in the Elantra is really different than highway mileage. 23 in city like conditions is pretty normal. The wide open highway is where these cars shine.

i drive a fair amount of highway and bumper to bumper traffic. I get 30-31 in my HD. I got 35 mpg when i went to north carolina last summer.

I filled up today and calculated my fuel economy. I got 8.4L/100km or 29.4 MPG for mostly city driving, but there was one shorter highway trip involved as well. Not bad but from the specs I should be getting 8.2L for pure city driving so I'm not impressed yet. My car is still brand new though.

My Elantra is a year old now and just a tad over 20,000km. I get 5.6L/100KM or 42 MPG on the highway with me and one passenger, a full tank of gas, a loaded trunk with luggage and food for a week, no A/C and CC set to 100km/h.

In the city I get 8L/100km or 29MPG, all city driving mixed with mostly non-rush driving and some rush hour driving traffic.

I've managed to keep the running average above 26.5mpg for two full tanks now, with mostly commuting 10 miles to work. Either I calmed down (maybe a little) or the CarPC was really working the alternator (doubt it) or the fuel mixture changed for summer, because I was getting 24mpg before. '03 manual 98,000mi. That reminds me the NGK Iridium spark plugs have around 60k on them now... oh well.

In my 2007 GLS auto I typically get between 27-29 mpg with about 70% highway and 30% city. I have a very light foot and generally do 65mph on the highway, also I very rarely use my A/C.

I've always thought these mpg numbers were kind of on the low side but maybe it is because I live in San Diego and there are a decent amount of hills.

Well, I just drove home from Ohio today. I have an 09 Elantra GLS, auto trans. The drive was 450 miles (roughly). I filled up once and got an avg. mpg of 32. Now this was driving mostly uphill, with luggage, two people, and driving at around 85 for 90% of the trip. I'm very pleased. On the drive to Ohio from my home I got 39 mpg, with only one person (me), about 90 lbs. of luggage, and some nice long downhill areas (gotta love neutral!). So far the car only has about 2200 miles on it. It runs very smooth, no issues, suspension seems perty good too. I will be going back to Ohio on sunday, July 5th, with that second passanger and our luggage. I'll see what I can get again. Then next weekend, I will be driving yet again back to PA from Ohio, only this time I'll be alone. So, I'll keep you guys posted on the mileage. I will be giving the car it's first oil change tomorrow....going from "break-in" oil to full sythetic.

Just did fill up #2 on my new 09 SE. Tank #1=32.2, Tank #2=31.7. City/highway about a 70/30 mix. A/c blasting almost all the time. I'm a happy camper so far!

Just changed oil and air filter, using Mobile 1 5w20 with stock filters, I did a drive to south New Jersey, to work a week and back and forth to Long Island. About 414 Miles, 10.5 Gallons of gas used.

Would of been higher, but Long Island traffic was bad, mostly not moving for 2.5 hours.

I really think the Automatic HD is great on gas. It better be considering the acceleration....kind of reminds me of how a hybrid drives.

The car seeing as its an automatic would most likely not save you any mileage by putting it in neutral. Also it's safer to just leave it in drive. You have more control in case of a split second wreck or something.

My highway mileage is well into the 30s, but my city mileage sucks, it is in the low 20s. My car is a manual, I drive like a granny most of the time, and my tires are always inflated properly.

I have my tires at 38 PSI. When going down hills I think you save more gass if you put the car in gear or even in a lower gear, 3rd or 2nd.
