Kia Sorento Real World MPG

keinodogkeinodog Posts: 2
I know my 2011 FWD Sorento is not broken in yet, but I'm a little disappointed in the mileage I'm getting. I've also noticed other comparative models, eg. Equino x, CRV, RAV4, etc., are also not doing so good according to forum reports.

Some observations I made today. I did a 30 mile run on the turnpike today. For the first 27 miles my mpg creeped up to 23.4 mpg while traveling on cruise at 70mph. I noticed after about 22 miles, my mpg pretty much stayed at 23.4 mpg. At 70mph, the engine was doing 2500 rpm. I then reduced speed to 55 mph and was doing 2000 rpm. My mpg began to increase. By the time I finished the 30 mile trip, my average was 25.6 mpg. Keep in mind the car has only 450 miles on it now.
One point I would also like to make is that my 03 Accord gets 32 to 36 mpg on the highway. It has a 5 speed auto tran compared to the 6 speed Sorento. The Accord is doing 1900 rpm at 55mph and 2300 rpm at 70mph. Both engines are 2.4 I4 engines. Yes, I know the Sorento is heavier, but I'm beginning to think KIA could have made the 6th gear a little taller in order to increase fuel efficiency. At 70 mph, very little HP is needed to maintain speed. Supposedly the final gear ratio on the Sorento is .77 but the Accord is .659.
There in lies much of the mileage difference. Don't expect to get anywhere near the EPA 29 on the highway estimate traveling 70mph.

I'd like to see others report their results on both the I4 and V6, FWD and AWD.

    The KIA is MUCH heavier.... bet the KIA weighs a good 1500- 2000 lbs or more than the honda so you are pushing a lot of weigh...unless it has drastically decreased since the original 03 was 03 weighs close close to 5000 lbs..... and would get 20 mpg on a good day......

    2011 Sorento curb weight: 3763 lbs....175hp/169 ft-lbs torque 2.4L I4 engine

    2003 Accord curb weight: 3128 lbs....160hp/161 ft-lbs torque 2.4L I4 engine

    -Should not be that much difference in mileage. Sorento is heavier but has more torque and horsepower. I still believe the difference is mainly final drive ratio. Why wouldn't KIA make better use of the 6th gear?
  • I had a perplexing MPG issue with my 08 Mazda 3 GT hatch which I was able to resolve by doing a reality check on the numbers the old fashioned way- with a fill up and calculation. I discovered that in many instances the computer readings were 3 to 5 mpg short of actual based on same pump refill. I do not know if the new Sorento has the trip computer feature but if it does, it might be worthwhile not to assume that the readout is entirely accurate and try it the old fashioned way of computing the miles.

    I just bought Sorento EX V6 AWD. The car computer says I am doing 13-14 MPG after I drove about 10 miles in the neighborhood on a Sunday. I will do the old-fashioned measurement to calculate the mileage per gallon myself. I will follow up next Sunday with the results.

    That's what I get with the 2007 Honda CRV with 25k miles on the clock. You can't go buy a 10 mile drive. After a few miles of different driving and break in, do the old fashioned method - filler uip, drive some mileage on 'er, then fill er up again. Do it a few times over 400-500 mile. Then you will have pretty accurate MPG. BTW, the Honda electronic calcs are right on the money....

    It's not just hp and weight. There is also aerodynamics of the vehicle of which the Accord is much more smoother moving through the air. At over 55mph, pushing the air is a big factor. Also, when you have more hp/displacement it is logically going to require more fuel to fill the combustion chamber. Computers are nice but there are some basics involved too.

    I've only driven about 30 miles on my 2011 AWD V6 Sorento. AVG about 18-19 MPG so far in city driving.

    I live in Woodland Hills CA and drove mine up to Lake Tahoe (about 500 miles one way) a few days after purchasing the Sorento. It only had about 200 miles on it when I began the trip. I was driving pretty fast most of the way (about 80-85) and wasn't expecting to get that great of a mileage. However, both the trip computer and my own calculations showed that I got about 29 MPG. Could it be that the sweet spot on the Sorento is at a higher speed?

    I have a 4 cyl 2011 LX with the 6 speed automatic.
    After 3000 miles of city and urban driving [averaging 21.2 MPG] I took the car on a highway trip of 188 miles. It was 95% interstate highway at 70 MPH and 5% small town stop- and go. I averaged 27.4 MPG. Love the Sorento.

    P.S. The trip was to and from a destination.
    A 10 MPH tailwind there and a 10 MPH headwind back.
    I think wind can be a big factor on these larger vehicles.

    good to see a steady increase in MPG for the later model year Sorie.....03 here and on a good day I get 20 MPG Highway and 15-16 around town,abeit an AWD 6 cylinder here......

    I have a 2011 Sorento EX with 4 cyl 6 speed automatic FWD. Currently have 5000 miles. I have logged every gas fill made and average just over 22 mpg. It doesn't matter if this is 100% freeway driving at 70mph or a general mix of city/highway. Best ever was 24.6 mpg with a 40 mph tail wind behind me. All dealer says is "wait until it is broken in". I'm still waiting....

    Do not believe this break in nonsense it is dealer b.s.
    Today's cars do not need a break in period under normal driving conditions your mpg.
    will not get better after 1000 or 5000 miles.

    I don't think most new cars need a break-in period either, but you should check the owner's manual.

    However, on my last new car, the mpg got better and better over time, and really didn't hit its stride until 10,000 miles or more.

    I have a 2011 Sorento LX4 with 2500 miles. The miles are about 75% highway, 25% city. My mileage so far has been about 14-16 in town and 20-22 on the highway with brand name gas and 65-75 freeway speeds. So far the fuel mileage is very disappointing in this otherwise excellent vehicle. :(

    I have a 2011 Sorento EX V6 Fwd with just over 1000 miles on it in which about 360 of those miles were put on this past weekend on a trip from Columbus to Pittsburgh and back. I started tracking our driving on the tank prior to our trip and we filled up as we left Columbus and got an actual 19.1 mpg which was about 90 to 95% city driving. The second fill up on the way back which was on road that at times was 2 lane 55 mph with traffic and other times 4 lane expressway at 70 mph. Ran into a good amount of construction and also had some city driving while in Pittsburgh visiting relatives. Also, anyone who has traveled between the two cities will tell you there are many long steep hills to go up and down. The Actual MPG was 23.92 and the cars computer read out was exactly 24 mpg. I thought both fill ups MPG was outstanding on a vehicle that will only get better as I put more miles on it. I had a 2003 Hyundai Sonata V6 that I gave to my daughter a couple of years ago and it didn't really start getting it's full MPG potential until it had about 5000 miles on it. It was rated 27 on the Highway, but I usually got 30 mpg. I only bring up the Hyundai because I consider Kia and Hyundai pretty much the same company.

    I don't understand why your rpms were running 2500. My 2011 Sorento EX V6 FWD runs right on 2000 rpms at 70 mph.

    Its been a couple weeks since I bought my new 2011 Sorento 4cylinder LX automatic. I am very skeptical of the mileage. The mpg average constantly shows 26 on my sorento mpg computer. Is this accurate or is it usually the real world is higher or lower than what the computer shows? If the real world is lower, by how much in terms of % is it lower? Any feedback and opinions would be highly appreciated. Thanks.

    The computer in my 2011 EX V6 is pretty darn close. Maybe up to .5 Mpg above actual. Just figure it out manually for a couple of tanks after you fill up. I have about 2400 miles on mine and I ran up to 26.3 MPG on 4 lane and 2 lane roads between Columbus, Ohio and Pittsburgh, Pa. Lots of road construction. My final overall MPG average that the computer read was 25.8 MPG which I figure will turn out to be at least 25.3 which I am more than happy for a V6 276 HP engine with the A/C running and very hilly to Mountainess terrain for at least 1/2 the trip. Only been getting about 18 MPG in suburban driving which consists of very short trips by my wife of mile to and from work and shopping. My disappointment is that at about 600 miles my climate control sensor went bad. Took 2 weeks for the dealer to get the part. Now this morning I discovered as we were leaving Pittsburgh that it has quit working again! :sick: I'm getting to be concerned that Kia really hasn't improved their quality. We also have a bad rattle already in the passenger door fake plastic wood strip. :(
  • 1. Go to the gas station and fill up the fuel tank.
    2. Record the mileage, before even pulling away from the pump (Mileage A).
    3. Drive normally until the next gas-up.
    4. Fill up the tank again (preferably at the same station using the same pump as pumps may be calibrated differently). This time, pay attention to how many gallons it takes to fill up the tank. This is usually shown at the pump and on your receipt. We will call this Gallons B.
    5. Record the mileage again, just like before. We will call this Mileage B.
    6. Subtract Mileage A from Mileage B. This will give you the number of miles you drove since your last fill-up.
    7. Divide 'miles driven' by the number of gallons (Gallons B) it took to fill up your tank. This will give you your car's MPG.


    Let's say you have a new Toyota Prius and want to track its mileage:

    * Trip A: Added 8.663 gal at 3,117 mi
    * Trip B: Added 9.251 gal at 3,579 mi
    * Trip C: Added 8.876 gal at 4,017 mi

    Mileage Calculation Answers

    * Trip A: It doesn't count. It only is useful as a baseline.
    * Trip B: (3,579 mi - 3,117 mi) / 9.251 gal = 49.9 mpg
    * Trip C: (4,017 mi - 3,579 mi) / 8.876 gal = 49.3 mpg
  • Break-in periods are absolute nonesense now days. There might be a slight increase of 1mpg over 10k miles, but that will be about it. We bought a Sorento LX AWD and had to return it within 30 days because the gas mileage was extremely terrible. Not only that, the AWD 4cyl is completely underpowered. In town it's ok, but on the highway it is TERRIBLE. We averaged about 20.5 mpg over 25 days. On the highway with hills it got as low as 18 mpg. We were solely disappointed. My wife made me take it back for a V6 and now she averages the same mpg but with soooo much more power. We still don't really like it, though, because the EX has an even stiffer ride and the front seats are terrible. We will probably go back to a CRV....can't go wrong with those.
