"Well if you read through this thread and others, there people getting mileage just like me. "
 
Of course there will always be a relatively small number that buck the average for whatever reason. Unusual mechanical failure or whatever.
 
But the overall average of Focus drivers are hitting the EPA estimates. Just look at fuelly.com. The 424 2012 Focus owners there are reporting an overall average of 31.4 mpg, right on the money with respect to the EPA combined rating of 31mpg.
 
Whereas the 174 2012 Elantras reported on there are getting ONLY a combined rating of 29.8 mpg, relative to the higher EPA combined rating of 33 mpg.
 
Focus: 31 EPA combined rating - 31.4 real world average
Elantra: 33 EPA combined rating - 29.8 real world average
 
Hopefully it's clear to you now why Hyundai got into trouble and Ford will not.

The numbers you gave 424 & 174 are a small number out of the total sold.
Not a good comparison.

Ever heard of statistics? That's called a sample. There's no reason to believe the data in fuelly.com does not represenent a fair sample of all Focus owners.

Yeah I've heard of statistics. What is that sample against 1,000, 100,000, 1,000,000?
 
You need to know that, otherwise thats a small sample.

The minimum sample size for a 250,000 population (abt. the number of '12 Focuses sold) and 95% confidence level is 384. So I have 10% more than I need.
 
Will you stop the petty bickering now and accept the fact that you are in the vast minority of Focus owners getting crappy mileage?

Only when you curb your fan boyism and realize that there is a real concern for some of us. Maybe you just need to stop replying to these and move on.
 
That said, I'm interested in what happened to the guy who traded in his Focus for a Corolla.

Not fan boysim - rather a search for the truth. And I do realize there is a real concern for some of you. There probably are a few cars out there with some as-yet-undiagnosed mechanical problem affecting fuel economy. But I also realize, unlike you, that based on the hard real world data out there those with fuel economy problems are in the minority.
 
Maybe you just need to stop replying to these and move on.
 
Nah, your rash generalizations need a counterpoint for all of the current car shoppers coming on here to research the possibilities. They can read your and my comments and decide for themselves.

Well based on fuelly.com data, the Corollas for the past few model years are averaging right around 31mpg, the same as the Focus. So I wouldn't expect any dramatic increase in mileage. And just like the Focus, there are Corollas on there reporting averages in the low 20's. Just depends on driving habits and traffic condtions.

Then I will continue to be that squeaky wheel.

Let's get away from throwing the snarky barbs at each other and stick to discussing the mileage issue please.
