If you get, say, 39mpg at 65 I'd been the mileage would still be over 33mpg at 80mph. It would drop off fast from there. In a small car with good CD rolling resistance plays a more important role in total drag than it does for a big SUV or pickup and rolling resistance doesn't increase with speed the same way aero drag does.

See Popular Mechanics' testing. MPG in the SFE version went from 47 @ 55mph to 33 @ 70. At that rate it's probably closer to 30 @ 80.

Nice info...

The Hyundai is closer to my expectations than the FF and suggest that the FF isn't as Aerodynamic as I thought and certainly not as aero as the Hyundai.

That's disappointing given that I live in the desert south west and the speed limits here are 70mph to 80mph so driving 80mph is pretty common. My current car (I have a 2012 FF Titanium 5-door Sonic Blue on order) is a 2004 Toyota Matrx XR and my lifetime average is about 33mpg. I get about 32-33mpg at 80mph. The Titanium I have on order will also have the 18" wheels with 235mm wide tires so I'm expecting a couple mpg less.

The Elantra also weighs 204 pounds less.

Weight won't have that much of an effect with highway driving.

Let's not forget though that the Focus matches the Elantra's city and 55 mph economy in their testing, which is pretty good given the Focus's weight and horsepower penalties. That would seem to justify the DCT as an efficiency increasing measure.

But then you look at Consumer Reports testing and the overall averages on Fuelly.com and you see the Focus is generally 1-2mpg behind the pack, and even behind the '07-'11 Focuses. That makes you wonder if the supposed efficiency benefit of the DCT is a crock.

It really is a bit of a mystery why the Focus can't seem to match the efficiencies of these other cars with their torque converter autos.

Go on fuelly.com and look at similar '12 Focuses. You can go into each user's page and look at their mileage details. Most include pics of their cars so you can see if they have the 18's. That'll give you a good idea what you can expect.

Go ahead and 204 lbs to your Focus and let us know how that works out for you and your fuel economy.

Adding weight will lower mileage under all driving conditions but mostly city driving. At highway speeds aero drag is much more important than rolling resistance so the effect of an increase in weight of 7% will be noticeable in city driving but almost non-existent in highway driving.

I'd guess that in city driving, when the average mpg is, say, 28mpg, adding 204 pounds would reduce the mileage to, maybe, 26.5mpg and more likely 27mpg. At highway speeds where the average mpg might be, say, 36mpg adding 204 pounds might lower it to about 35.7mpg.

Yep, just my estimates...

Assuming you lived someplace perfectly flat and level, add in any hills/ grades then the weight is doubly important, because the rolling resistance is combined with the grade resistance which increases the road load force exponentially with increasing grade angles.
