But what leads me to believe it (besides others' experiences on this forum) is the Popular Mechancs testing that showed the exact same thing. With a carefully-measured 150-mile highway test they showed the Focus's mpg way below the Elantra's, while all other economy metrics were about even.
Another good comparison. You notice in the real world numbers it's just about deadlock for city or 55MPH hwy. However, at 70MPH the Focus number goes in the tank. I would just LOVE to know what the factor is causing this. (Maybe if I just keep asking over-and-over I will get an answer
). I took a trip from Ohio to South Carolina in April and was getting 33-34 on the hwy at around 70MPH. Last week, I did a road trip again at 70 MPH and was getting 39-40 MPG. The SC trip was windy and though the hills of WV, VA, NC. This last week was in Michigan with flat roads and light winds. As you noted, the C&D was not specific about the condition of the high-sped highway test. Maybe the Focus falls off the pace more in adverse conditions??
Note: I did get to see the C&D article on fun 40MPG vehicles. Did you notice on that chart with the MPGs, the other two factors were "0-60 time" and "fun factor" and the Focus trounced everyone in both of those categories. So, maybe this is just the price we have to pay for having the most fun car. I'm good with that. (But I still want to know specifically WHY.)

I drove from Wilmington, DE, to the Finger Lakes of NY in March, up 476, then some back roads, and averaged 39 mpg, made the trip on half a tank of gas. I know this has been said many times, but how you drive is the big difference. I'm easy on the accelerator and the brake because I want the best gas mileage I can get. My primary reason for buying the Focus wasn't performance.
This is quite similar to my general MPG experience..
