David: Thanks for the informative post from an experienced tech that actually worked on Hyundais. We bought a 2012 Sonata GLS 2 months ago and the car is great. 65-70 MPH yields 36-38 MPG and even at 75+ it gets 33. City MPG all over the board due to varying conditions, but close to EPA.
I agree with your comments on dealer service and warranty. I feel the warranty is worth a lot and will definately get the oil changed every 3000 miles to protect that warranty. We also got the Assurance guranteed trade in value in 12/2011 that is not available on all the cars in 2012. 67% after 30 months is pretty good backup if you wanted a new or different Hyundai.
Our 2.4L 6-speed auto trans shifts very well and does have the programming set up to upshift faster than downshift for MPG maxxing.
Great cars for the money and with that warranty the Sonata was no brainer. The highway MPG is close to the Elantra but not the city.
Thanks again for the facts and professional view.

Great comments in a real world view. See my previous post to David's comments. We see exactly the same changes with speed on or 2012 Sonata. Max MPG at 65-70 using Shell or BP (Amoco). City MPG only 22-24 due to added weight of Sonata. We also avoided the low profile tire trap and run the 205x65 HR16" tires at 35#. A little common sense and paying attention to details results in maximizing the MPG and at $4/gallon and headed up thanks to the oil companies business plan of wanting to pay more for imported crude to make 6% of $100/bbl vs. 6% of $35- oh well!
#267 of 774 Another Winter Tale of 2 Tanks: 30/70 vs 75/25, Hwy vs City
Feb 26, 2012 (8:40 am)
Had to fill up twice in past 2 days.
First tank was about 30% hwy/70% city. 30.20 mpg (227.7 miles and 7.540 gals). Computer est. 32.0 mpg and said I averaged 28 mph. Did the highway driving with 2 adult passengers.
Second tank was about 75% hwy/25% city. 34.15 mpg (186.5 miles and 5.461 gals). Computer est. 37.6 mpg and said I averaged 51 mph. Did about half the highway driving with 1 adult passenger.
Weather was cold and windy, mostly in the 30 degs-40 degs for 1st tank. 2nd tank all in 20 degs. Had ECO on entire time. Used regular unleaded (non-ethanol). Tried to use cruise control for maximum amount of time. Drove at posted speed limits. While some of the hwy at 70 mph there were also portions at 65, 60, and 55 mph.
I find the AT fascinating. My tach shows about 1500 RPMs for 25 mph (4th gear, direct drive 1-1), 35 mph (5th gear), and 45 mph (6th gear). The manumatic shifting feature has an override, so I can't put the car into 5th at 25 or 6th at 35 mph, even though I wish I could and the car has enough torque to keep it going nicely on level ground. This car really seems to max out FE in the 40-60 mph range, in 6th gear (the deep overdrive), but the FE craters from standing start to 25 mph. So lots of stop signs and stop lights will kill FE. And I see a noticeable dropoff after 65 mph. By time doing 70 mph FE dropping fast.

I've seen the same thing on nearly every car I've driven (for which I've measured fuel economy) over the past 20 years or so. 50-60 seems to be the sweet spot from my experience, although it's possible to get very good FE at lower speeds too if the tranny is geared for it. For example, at 35-40 mph in my Sentra with CVT the engine is turning at only 1100-1200, so I can get good FE cruising at those speeds. Except I never get to stay at those speeds very long since that would be in-town driving, so there's stops/starts.

My 1st tank of gas 2012 GLS AVERAGE 29 mpg . The 2nd tank same thing,half way through reset went 25 miles on highway 60 mph criuse control got 40 + enough said!!! The key word is AVERAGE!!! Case Closed!!!
#270 of 774 MT Results for Economy 5-door hatchbacks
Feb 27, 2012 (8:46 am)
The April 2012 issue of MT has a 7-car test of economy hatchbacks with manual transmissions and the Accent won both the test and had highest FE achieved, and Rio came in last. The FE numbers achieved were interesting:
Accent SE: 32.4 mpg achieved (30/40 EPA mpg)
Yaris SE: 32.3 (30/38)
Fit: 31.0 (27/33)
Rio: 30.8 (30/40)
Sonic LTZ: 30.6 (29/40)
SX4 Sport Back: 27.8 (23/32)
Mazda2: 27.0 (29/35)

The keyword here IS average and people are having a hard time getting the average they should be getting. I just hit 3000 miles on my Elantra and have yet to get anywhere close to 40mpg except when the reset is it. It will steadily fall WHILE driving at a controlled speed of 55mph. In 30 miles of continuous driving with no stops or steep inclines the mpg would go from high 30's to 35.
When I picked up my car from the dealer after they failed to find any issues with it a lady was there to pick hers up as well. Same model and she was getting in the teens for city driving which is what I was getting when I drove around rockville one morning but that was my only experience with 'city' driving. She complained that she traded in her 98 Toyota for this but was getting worse gas mileage.
Prior to meeting her I had asked the Adviser if they had other people with this issue and they responded with no. Either the testing procedures have changed to allow for better MOG ratings than in the past or this car just does not get the stated averages.
In a 6 day work week with a total of 24 highway miles at 55mph daily roundtrip and 1 miles total of getting on and off the ramp (1/4 from house to highway and a 1/4 mile from highway to work) we cannot stay above 32mpg average. This is using mild acceleration and cruise control. Now for those who say this isn't enough time to warm up the vehicle I have tried letting the vehicle warm up longer before leaving and just idling causes the mpg to drop and in 3 days of doing this the average mpg had dropped to 29.
You have to be an idiot to reset the computer and take it on the highway and say that you're getting 40mpg because it reads that at the beginning. When reset they all read high until an average can be given. The problem is that people cannot seem to get anywhere close once more than a few miles have been put on since the computer was reset.
The service adviser told me the mechanic was able to achieve 41mpg in 5 miles of driving on the highway so nothing was wrong. First, I have no idea how they did this unless he reset the computer while at highway speed and not from the shop or he would have never got that rating since I haven't. Second, when I started up the car it read 27.8mpg average. I find it hard to believe that this computer is actually reading an average accurately if you can go from 41mpg to 27.8 with only a short distance from the dealership to the highway.

This idiot reset the computer MANY times to get the instant MPG under varying conditions. Highway means ALL highway NOT city/highway mix.
The comment about MPG going down at idle is very enlightened; using fuel without traveling any miles would equal 0 MPG. seems to me that would impact your average MPG also. The instant MPG is a great way to learn your vehicle and also to maximize your MPG experience. ALL city = minimum MPG. ALL highway = minimum MPG. Mix of both equal something in between.
We have the 2012 Sonata that has the same computer software - what cool cars - they can even lear which is more than some of the operators!

This is interesting in that the Accent and Rio have the same powertrains and are close to the same weight. So, why did the Rio get lower FE than the Accent? One reason might be if the Rio had the 17" wheels; Accent's are 16".

"The keyword here IS average". That means half of you will get mpg lower than the average.!
