Anybody get terrible mpg?
Yeah 48 seems right there in the happy spot. Pretty much the least amount of throttle required to maintain the highest MPH in the highest gear is going to be the best for any car. Every transmission will differ but for me in the 5AT, 48 is just about as good as it gets.

Unimaginable huh? The 7 speed would be marginally better, still under 30mpg on the highway, that seems to be the absolute cap on these. Plus, the 5 speed is a proven reliability beast, its not as unbearable as you think 
.. The more I think about swapping in the 6 speed I have the more I think how much I'll miss the paddle shifters, I love those things for spirited driving days and don't miss the clutch AT ALL in the other 95% of my daily driving days. Hope your plastic CSC doesn't go out on ya dude..

I didn't even get that exact, I just kept track of the miles driven from when the gas nozzle clicked off on the pump to when the dash said I had 25 miles remaining. I could possibly get a little better if it was a more consistent speed limit but from STL to my house it ranges from 55-75 MPH with numerous small towns in between where traffic picks up. I'll have to redo it when I go to Chicago or Dallas this summer. I REALLY want to break into the 30's on the 5AT.. High hopes maybe..
If you want to use the cruise control then you should keep around 56mph and unless you have hills etc. you will probably break 30mpg.
5at's problem is when you get closer to 70 mph, the rpms are simply too high to get good mpg at that speed, 7at's tall 6-7 gears help a lot.
Also if you go below 50 the mpg of 5at will be almost the same as the mpg of 7at (around 45mph you will probably approach 35mpg).
Unfortunately we don't really know how much mpg 7at brings since the data is from different roads, different elevations, different fuel grade and these make a huge difference.
I have a 5at coupe and I have broken 30mpg many times and I am talking about roundtrips, one way is misleading. If I hypermile and stay around 62, I can do 31+ mpg.

Good to know. I used cruise control at about 75mph but there are several hills and slowdowns of traffic etc.. I would love to break 30 too.
I was tire shopping today and noticed my current tires (G-Force COMP 2) are terribly rated for gas mileage although they are very very highly rated performance tires. I wonder if I got the all seasons or just another brand for better mileage if that would make a noticeable difference? Not sure the loss in performance is worth the small gain in mpg though.

A thousand miles on the PSS, I can't say the mileage increased or decreased. Averaged around 24-25 mpg with mostly highway and backroad driving. About the same as I got last fall for the same trip.
Frictional drag vs aero dragplot
Missing is engine drag which is proportional to rpm. Thus the desire to drive in the highest gear at the lowest speed.
A Newton is a unit force and is equivalent to the weight of an apple at Earth's surface.

That's going to be based off of the nav screens averages since thelast reset, if ever. Go reset that in the mileage screen and see where it puts you for your current driving style.
Unless your gas gauge is wrong there's no way lol.. Its a 20 gallon tank so even if you wait for the light to come on there tends to be 2+ gallons remaining. Although even then there may be more, my roommate and I took his sedan to PCB last year and we drove it almost 100 miles after the light came on to the nearest gas station lol

I think it's messed up, my range on full tank says 220 but drops to 210 right after I drove out of the gas station and after driving about 14 miles the gauge shows 3/4th tank left..
