Popular Mechanics did investigate and guess what? They hit the EPA numbers.
 
I really wouldn't call it an investigation. They tested one car in very favorable conditions and it hit the numbers. CR did the same thing and it didn't quite hit the number while most of the other high mpg cars did and even surpassed them in most cases. I think that is part of the problem. The vast majority seem to be doing well but there seems to be a large number that aren't.
 
I also see other forums with complaints about mpg re other cars. However, the sheer number of complaints about the mpg with this car has drawn a lot of attention with consumer's groups and the press. Never saw that with the Mazda3 so I assume the numbers were pretty small on the grand scheme of things.

#473 of 745 Elantra vs Ford Focus by dc_driver

Apr 30, 2012 (2:25 pm)

Automobile Magazine did a shootout between the 2011 Elantra and 2012 Ford Focus, here is what they found:
"Hyundai is also the more earnest in following through on its fuel-efficiency claims. Both Ford and Hyundai are heavily touting their small cars' ability to achieve 40 mpg on the highway, but the Focus only does so when equipped with a dual-clutch automatic transmission and a special fuel economy package. Our test car, equipped with a five-speed manual -- no six-speed is offered -- is rated at a still impressive, but less sensational, 26/36-mpg city/highway. The Elantra, on the other hand, is rated at 29/40 mpg regardless of trim level and with either the six-speed automatic that was in our test car or the standard six-speed manual. Over the course of our three days of mixed city and highway driving (including the round trip to D.C. from Ann Arbor, MI), we observed an indicated 36 mpg in the Elantra, versus 33 mpg in the Focus."

With mixed driving they hit 36mpg on a 2011 with a six speed automatic.

"Mixed" driving is the key. I would argue that the mix factor is the reason for the variation in MPG results on all cars - not manufacturing reasons. ALL highway miles results in EPA or better while all city miles results in missing the EPA estimate on the low side. It is the type of city driving - both the stop & go frequency and the driver that affects the city MPG to the negative - not the maechanics of the cars.
Another point is that larger engines are more forgiving than smaller engines when getting the mass moving from a dead stop. Larger engines in older car models often achieved better MPG than smaller engine in same model. Cars used to be engineered for overall driveability - now EPA rating is king.

Think too many people overestimate the amount of TIME they spend on highway and underestimate the amount of TIME they spend in city. City stop-and go traffic, esp. where you just sit at a stop sign or light, adds a lot of time but no miles and craters your MPG.
 
Think too many people underestimate their SPEED on highway, spending more time at higher speeds than they think. You won't get 40 MPG driving 70, 75, or higher MPHs. Max fuel economy is in the 50-65 mph range.
 
I have no difficulty seeing people driving a lot of MILES on highway getting 33-36 MPG due to (1) driving at higher speeds or (2) spending a decent minority amount of TIME idling at stops.
 
Anyone seriously looking at their specific car's FE needs to look at the computer's estimate of MPH and the elapsed time, both of which should be reset after each fill up.

>>>Even though the 40 is more likely coming from the EPA and not Hyundai corporate
 
Actually, it was the other way around. Hyundai submitted the numbers to the EPA and they verified the numbers: linky

#477 of 745 Huyndai Mileage by disatisfiedone

I drive a 2012 Elantra 60 miles a day all highway. After 2500 miles I am averaging 32mpg. Complaints to Huyndai USA gets me directions to see dealer, complaints to dealer get responses to write Huyndai (they call that a circular refrence right). Would not bother me if Huyndai would not continue to run ads on TV about 40mpg. Something about truth in advertising? Hate to be paranoid but how many of you getting 40mpg work for Huyndai? Taking mine back to see what I can get for it, oh did I forget to mention the oversensitive steering and just waiting to get pulled over for driving under the influence.

What does your computer report for the avg MPH?

#479 of 745 Idling hurts a lot by indeed

May 06, 2012 (7:28 pm)

Getting an average of 8.5L/100km (27mpg) between my break-in period (first 1000 km). I drive conservatively, allowing it to shift before 2,200 rpm regularly, and rather let the gear slow down the car instead of breaking it. Only went on highway twice and recorded 6L/100km (39mpg) going at 110 - 120km/h (70m/h - 75m/h) on Canada's 407 for total of 70km (45 miles)
  
The car idling hurts a lot, and it depends on how often breaking/stopping. The dashboard display has it raised 0.1 L/100km every one or two minutes when I was stuck in traffic.
  
However, Canada has it registered as 6.9L/100km for city (34mpg) and 4.9L/100km for highway (48mpg), so I am still looking forward for better gas consumption.

Yes, knowing average MPH is absolutely critical when evaluating reported MPG figures per tank. My most recent 2 fill ups (both with regular non-ethanol) show the dramatic impact of not spending so much time in city stop-and-go traffic:
 
- Avg MPH= 35 and achieved 35.45 MPG. Drove 231.4 miles and used 6.528 gals.
 
- Avg MPH= 24 and achieved 29.46 MPG. Drove 258.5 miles and used 8.776 gals.
 
So a 46% increase in avg MPH or an 11 MPH average increase leads to an increase in FE of 20.3% or 5.99 MPG!
 
Computer FE estimate continues to read about 7-9% too high. Computer estimated first tank at 38.4 MPG (got 35.45) and second tank at 32.3 MPG (got 29.46).

Great analysis! The 6-speed trans is not in highest gear until vehicle speed reachs minimum speed. so when the vehicle speed is higher the trans is in a higher gear and the RPM's are lowest. Result = higher MPG. Not really intuitive but your results and MPH recor explains the results.
Thanks for the work and the thinking. Explains much of the confusion among drivers results.
