Hi,

I have a 2008 Elantra SE manual trans. and the car is really economic, on city I have average 27 MPG and on the HWY 38 MPG. I drive on HWY with my cruise control set at 75 Miles.

If you turn off the A/C probably you can get 40 MPG. also I want to let you know that the car have the trip computer and as soon you fill up the tank they trip read 327 miles, but that is only a computer set up. as soon you drive on hwy and the computer recheck at 1/2 tank the trip reset and provide the new average and also on the AVG miles on hwy the car read 38. and city 27.5 MPG.

I think the EPA average on the window when you purchase the car is really bellow on the car performance. This new 2.0 L. engine has more performance than the previous model from Elantra.

I will recomend this car to every budy, the features, performance and confort is superior to Toyota, Honda, Nissan, and all american cars on the same category. You get a lot for less money. and the waranty is awsome.

Over here from the Accent forum. Your Elantra (33MPG) gets 1 MPG more than the Accent(32MPG) from the EPA.

Now, my wife's tough commute has been averaging v. close to the EPA highway mark on her Accent in mixed city, stop & go highway, country, & speed limit highway. I'm a feather footer & got the opportunity to take her Accent on 3 day trips over 1400, 3000, 4000, & 5500 mountain passes, 101 degree E. Washington, & Mt. Rainier. Suddenly, the car turned in tanks of 41.5, 42.6, & 45.1 MPG.

Yup, cars get up to such & such MPG, but don't expect it often.

I'd suggest doing the calculation over a whole tank of fuel. With only 103.5 miles driven your calculation may be skewed by the amount of fuel put in the tank.

An example:

103.5/2.707 = 38.23MPG
103.5/2.507 = 41.28MPG
103.5/2.907 = 35.60MPG

And using a higher grade fuel probably won't yield any better fuel economy. If you don't already, you'd be better off using name-brand fuel (Shell, BP, Chevron, etc). You'll just be wasting your money by using a higher octane gas than what the manuf. calls for.

And again, to everyone... I'm not knocking the Elantra. I think it's a good car, and with the last redesign it's a good looking car too.

Reason i use full as my marker, Is because short of draining the tank every time you want to know how much gas you used, Full is the only measurement you can be sure of Every single time.

so i am positive i used 2.707 Gallons to travel 103.5 miles.

Now as you use more fuel i could possible get more MPG then that, Considering less fuel makes for less weight, Also My car has less then 1k miles on it, So its not broken in, eventually i will get even higher Milage from a tank.

And one more thing, That 38mpg, was also calculated while using MAX AC with fan speed of 2, and a passenger.

Now if you mean Do the experiment from full a couple of times to get an avg, Im sure i can do that, Considering i commute that 100 miles every night, And wont have a passenger.

So more accurate info coming in soon.

I thought the topic for this thread was " is it possible to achive 38 mpg" if thats the case the answer is most definatly yes for a person who drives Avg speed on the highway a ton.

Also, i live in new england, So i have a different version engine in my elantra, Its the one sold only in Cali and New England if im not mistaken, it has less HP Etc etc, I suspect for emmisions and Corrision resitance.

Dont quote me on that but im sure thats what the dealer told me.

Maybe less HP for me equates to better milage out of my 4 banger.

I have an 05 Elantra w/5speed with 60,000 miles on it. I easily exceed the estimated EPA mileage for the car. I get between 38-40mpg going to and from work. I live in eastern Tennessee in the mountains. This is without the a/c on. Running the a/c costs about 3-3.5 mpg penalty

We have a 2007 Hyundai (automatic and PZEV). Coming up on one year of owning it and about 12,000 miles on it. We can reliably get 26-28 in around town driving and we've gotten as high as 39 mpg on an all highway trip.

Check out fueleconomy.gov for mpg calculations from other owners of the same make and model. Sign up for "Your MPG" and add your calculations to the list. We've been recently adding our calculations to the forum and we're averaging 32.7 mpg. With 22 people posting on the site, the current average mpg is 30.6. It also lets you enter estimates for how much of each tank was city and how much was highway.

We've seen an increase of around 2-4 mpg by trying the basic "hypermiling" techniques. They include:

1) use cruise control on flat highway travel
2) don't go over 60 mph
3) coast down hills and into stops as much as possible
4) don't accelerate quickly out of stops
5) keep accelerator level when going up hills and let the car do its thing
6) inflate tires to proper pressure
7) don't carry extra weight in trunk
8) leave a big cushion between you and next car to avoid stops and starts

Basically, around town you drive as if your brakes were shot or weak. On highways, don't go over 60 and try to hold a level speed. It increases fuel efficiency and the mpg shows it.

2007 Elantra SE automatic. I'm averaging between 35-36mpg combined city and highway.

I personally don't think advertising what some people may be able to achieve in a particular vehicle equates to false advertising. Just for some brief background on me, my wife and I just bought a hyundai accent, i'm hoping to average at least 36-38mpg in it. I would expect the same with an elantra (which i will be eyeing once the touring edition comes out!).

We traded in our honda Crv for the accent. My other car is a toyota yaris 5spd. I used to average 34-36mpg around town and commuting (20 miles one way, combo regular road and highway). which, is still slightly higher than current epa combined 32mpg (29city 35hwy). Over the last 2 months I decided to drastically change my driving habits. going the speed limit, coasting, no idling at long lights (when i am familiar with the light, mainly on my commute), not necessarily slower acceleration BUT keeping it below 2500rpm. the result?

http://www.gassavers.org/garage/view/167

40.76 average over the last 90 days, including the last 2 tanks close to 42mpg. that is over 20% increase over my previous numbers, and almost 30% higher than the current epa combined average.

using less gas feels good, driving slower has been less stressful, and it has saved us money. if $4 a gallon gas doesn't change your driving habits though, i don't know what would!

perhaps they should put UPTO 39mpg, but i dont think putting an achievable number on the windshield is false advertising imho.

I drove from Madison to CHicago and back, and got 39mpg. That's with AC also. Around town, about 30mpg. I have only 4600 miles on it.

I had a 2006 v6 Sonata which I traded in for the elantra and would get about 30mpg on hwy if lucky, and about 20 in city...miss the style/power, but not the $62 fillups.

My last 3 tanks have been very consistent, 95% city, 90% a/c use, 31mpg.

Cant wait to do a road trip, should get 39-40 I assume.

OK, I guess I'm not crazy. On a recent trip (all hwy), I filled my tank in Newnan, GA. Then, I topped off my tank when I got to Montgomery, AL. Now according to Googel Maps, this distance is 110 miles. When I topped off in Montgomery, it only took 2.550 gal to fill up the tank. My calculations show I averaged 43.137 mpg. This was with the cruise set at an indicated 74 mph (which in reality is about 71 mph according to GPS) with the AC blowing full blast about 50% of the time (off the other 50%). It was just me and approx. 55 lbs of luggage. Tire pressures were at 38 psi front 35 psi rear. I was simply amazed. Oh, and car had 31K miles on the odometer.

2008 GLS Auto about 1500 miles. I drive with a light foot, 80% or more highway, average 60-65 MPH with A/C on periodically. My first few tanks have been 34-35. That's a very nice start.

Could have bought an '09 Corolla, but would have just exchanged the better MPG for higher sale price.

I don't regret this purchase one bit.

Dad, is that you ? :bwekk: Actually, I am having very similar results as your son. I also have a 140 mile round trip commute via interstate, etc, and am averaging between 36 – 40 MPG hand calculated and an average over the past 12,000 miles. My trip computer is usually 2+ MPG “optimistic” compared to my calculations. I drive with a soft foot at around 65 MPH, but drive thru rolling hills, a total of 5 lights, and zero traffic. Interestingly enough, I seem to get better mileage when I drive a different route that is two lane with more hills, and I drive at or below 55 MPH. My mileage has improved slightly as the engine went over 5000 miles, and I am using Mobile One 5W-20.

I just bought an '08 Elantra ES automatic with a sunroof. I've logged about 1400 miles on it, and I'm sort of mystified how people on this forum are able to get such good mileage. So far, I've only been able to get about 30-31MPG, and I do about 90% of my driving on the highway, averaging about 75MPH. I don't slam on the gas pedal to pass cars. I do have the A/C on, but there's nothing in the car except for my own body weight (~145 pounds).

What am I doing wrong? By the way, I'm letting the trip computer calculate the MPG. It's accurate, right? I reset it after each fillup, both the MPG and the miles travelled.

Thanks,

- Sung

I just took a highway trip with AC on about 30% of the time and about 50 miles of city mixed in and I got 38 mpg on the nose. that was at 70mph almost always with cruise. I would say at 55 mph and no AC for all highway I could get over 40 easy. Mine's broken in too, at 11,800 miles

I have an 2008 Elantra GL Sport. It has 1700 kilometers = 1062 miles. I drive 80 kms. or 50 miles round trip back and forth to work. This includes rural roads and city. My trip computer tells me that I average 7.2L/100kms.

7.2L/100kms. = 39.2 miles per (Canadian )gallon

39.2 CDN miles/ gallon = 33.32U.S. miles/gal.

Canadian gallon =4.54 liters
U.S. gallon = 3.87
A difference approx. of 15%.

To check the trip computer to see if this was true. When I filled the car up and calculated the amount of fuel and my mileage. My actual miles per gallon and the trip computer are in 10's of a mile/gal in the difference. Thats pretty good.

What I will get on the highway i don't know yet.

I purchased a new Elantra GS Sport Manual (Cdn model) and with only about 400 KM (240 miles) began a trip from Western to Maritimes Canada, via the US (Chicago, Boston etc), about 3300 Miles 5560 KM, First day no cruise while I ramped it up and down in speed for over 1200 KM. Overall I' averaged about 47.43 MPG Imperial which is about 39.25 MPG US. Generally driving interstates at 70+ mph, with some stints over 80, some between 65-70.
Overall, I was majorly impressed with the drive of this vehicle,comfort, adn the fuel mileage.
Note I was alone, on long day drives, very limited start.stop, so this is about ideal, BUT I wasn't trying to max fuel ecomony but make it in 4 days fixed time frame!!
