Is not the definition of the "city" rating "stop & go traffic" (i.e., traffic lights and stop signs)? The City rating is 29 mpg and I get only 22 mpg.
My previous car was a 2007 Nissan Sentra 2.0S. It was rated at 25 to 33 mpg. With the same driving patterns as with 2011 Hyundai Elantra GLS, at 11,000 miles, I was averaging 25 mpg. I guess that means that Nissan's mpg ratings are accurate and Hyundai's are inflated. I wish I would have known that before I bought the car.

Yes, but when an engine is cold - really until it reaches full normal operating temperature - the ECU runs a richer fuel-air mixture. More fuel is burned to keep the engine running smoothly, avoid knocks/pings, and bring the engine up to temp quickly. With your short commute the engine is not reaching full operating temp so the ECU never switches over to the leaner fuel-air mix.
It's entirely possibly that Hyundai's and Nissan's engineers have different programming standards and different ways of handling their particular engine's characteristics.
I'm not making excuses for Hyundai, nor do I think Nissan's tech is necessarily better. Just trying to explain the problem with a short commute and that different manufacturers will have different approaches to engine management.
When you have some extra time, try running the car until the temp is full normal, and then some for a few minutes to make sure. Then reset the trip computer and see what mileage you attain.

2013 Elantra GLS, auto. After 5K miles and reading allot of posts about this car's MPG I think something is clear: your city mpg will vary between 22 to 24, while your highway will be around 34 to 35 (mile marker to mile marker, once at speed on a flat road) Combined = 27. Hyundai's claimed MPG estimate 15% overstated in city driving and 10% overstated on the highway measured by the ACTUAL FUEL USED / MILES DRIVEN. My 2007 Sonata gave me 17 city and 32 highway and a combined 23. My dealer confirmed this.
Hyundai gears its trannys to give high mpg's on the highway, but at the sacrifice of really bad mpg's in acceleration and in stop and go city driving. And those really bad city mpg's rapidly decrease a much larger number of highway mile mpgs. THE REDUCTION IN COMBINED MILEAGE HAPPENS FAST!
It's a game.

Just so it's clear. Every car for sale in the U.S. goes through the same exact EPA tests for both city and hwy. They are accelerated the same, braked the same, driven the same speeds, go through the same amount of simulated stop lights, etc etc etc. It's not the manufacturer's test...it's the EPA's test. The manufactures have to test them in strict accordance to the EPA criteria and the EPA randomly does there own tests to verify the manufactures. So the claims are the manufacturers but they are derived from the EPA test and not some arbitrary manufactures test. The EPA test is not just heavy, stop and go urban traffic simulation. It's a combination of urban, suburban, light blvd etc to simulate "city" driving in Des Moines as well as New York. They are both city driving but can substantially different mpg results. So they try to reach a compromise to give you an idea of what kind of a range you might expect. You have to apply your conditions and decide if you are probably at the bottom or top of the range for your expectations.
That said, it would be almost impossible for the average consumer to exactly match all the driving conditions that the test is made up of. If you actually read the EPA sticker it will give a range for city and a range for hwy with a number somewhere in between each boldly printed. I don't know what the exact numbers are on the Elantra but it is probably something like 22-32 for city and 34-42 for hwy. What that means is that if you drive only a few miles each way to work through a lot of urban stop and go traffic, your mpg will probably be at the very lowest end of the city range which would be around 22 or 23. That kind of driving is about the worse you can get.
It's been stated often that the Elantra doesn't have a lot of torque or grunt off the line. If someone was used to a certain amount of speed when taking off with their old car they may just push the gas pedal a little harder in the Elantra to get that same feeling of grunt or speed off the line. That will affect MPG greatly and possibly explain why another car may have performed as well as the Elantra even though it's mpg ratings were lower as estimated by the EPA.

The car is a rip off. Hyundai has totally mis lead its customers. They need to stop blaming the drivers.

I just purchased my Elantra last week, and averaged 31.9 mpg. Please note that the majority of my driving is hwy - 60-65mph and I do use the cruise control, as well as have it in ECO-mode. I've read alot of the posts and reflect back when I purchased my '06 Civic, which at the time EPA MPG 30-City and 40-Hwy, and I too was disappointed in the beginning when I wasn't achieving that mileage that had been posted on the window sticker. Several factors played into: 1. City driving - living in San Francisco, with it's many hills and numerous signal lights, I was achieving 23 mpg. 2. The break-in period for the car's engine. One has to take that factor into consideration. Once my car had acquired close to/over 10k miles, I noticed the mpg improved. I sold it to a friend of mine earlier this year and he liked the fact that I was getting mid-30's city/hwy combined driving, and achieved as high as 47.8 mpg straight hwy - driving from Sacramento to San Francisco, Bay Area - not bad for it not being a hybrid or diesel. Lastly, if you keep your car cleaned (washed regularly and waxed a couple of times a year), as a smooth finish allows the air to flow smoothly over the vehicle, thus reducing drag, keep your oil changed on a regular basis, clean air filters and proper tire inflation, will all contribute to improvement to your mpg. Heck, I got 31.9 my first week, and its only got a little over 200 miles on the OD, I'm anticipating continued improvements in my mpg as my car ages. I'm quite please with Elantra; quite the car for the small price - nice standard features that aren't usually found in this class of car. Best of luck to everyone!
