I know I've really been sort of a pain in the bumpkus. I do have a good tip for any of you out there who are frustrated with the way that the interior dash seems to not absorb armorall.
 I have another car with leather and I use armorall leather . For the heck of it I tried it on my Yaris dash and the results were fabulous. Give it a try! It comes in a brown jelly jar looking container.
 
I think it's made with petroleum however. This may reduce your mpg slightly. The way you guys drive it probably will not matter

>"Also, 60 mph is more likely to ever happen, not 55 mph."
 
fastrunner,
 
The whole numbers are shown on the speedometer; Such as 50,60,70 and so on. Whereas 55, 65 and so on are just little marks between the whole numbers. I personally tend to drive at the whole numbers. In 55 zones, I drive 60. In 45 zones I drive 50.
 
For some reason 70 seems like such a large number so I pretty much limit it to 61-65. Small numbers that burn less gas. Don't know how much real difference there is in MPG between 55 and 65, with todays more aerodynamic cars. But there is some. I do believe that if everyone was slowed down, I would probably slow down to less than 60 on the free ways. .
 
I expect a Yaris at 55 mph would get some really high mileage.
 
In the 70"s there was a 55 mph speed limit imposed, nation wide. I got used to driving it and found the mileage increased and the driving was a lot more relaxed.

Probably not more than once.
 
Everyone has their own preferences.
 
For me the "Trip" is part of the journey. Lots of things to see and do between here and there. It is OK to spend a little extra time on the road! Certainly better than sitting in a "Wait Here" area.

"I would have to take my Yaris back to the dealer to have cruise control installed though or I might find myself facing those serious consequences"
 
This describes me to a T. I simply enjoy driving, a concept and practice that many others simply fail to understand.
 
As far as lowering the speed limit, for the tree huggers that only care about extreme measures I would propose the following based on the facts, as the EPA fuel economy testing has established.
 
The highest fuel economy is obtained by driving at a steady rate of 32 MPH. Therefore lets' make that the maximum speed on the freeways, and highways. Just think boys and girls, how fun to save so much fuel! The planet earth will be smiling and you get the fun of spending most of your time in the car. The accident rate will collapse, the body shops will go out of business, and the poor souls that sell fuel will get rather grumpy.
 
Now we must also set the maximum speed for surface streets. Again simply consulting the studies that figure is 19.5 MPH. Just think how fun that will be. No worries about slowing down in a school zone as you are already well below 25 MPH. You have the pleasure of taking quite a while to get anywhere, and yet just think of all the roses you can smell. All the birds you can watch pass your car or whatever it is that you choose to drive or ride.
 
How simple. Just two speeds. 19.5 mph, and 32 mph. That will thrill you beyond your wildest expectations. Save the planet, Save gas, Save having to focus on steering your car, or having to use the brakes very often. Save money, Save everything except time. After all time is meaningless anyway when you are saving fossil fuel. .....

When I was young,
it seemed that life was so wonderful,
a miracle, oh it was beautiful, magical.
And all the birds in the trees,
well they'd be singing so happily,
joyfully, playfully watching me.
 
But then they sent me away
to teach me how to be sensible,
logical, responsible, practical.
 
And they showed me a world
where I could be so dependable,
clinical, intellectual, cynical.
 
There are times when all the world's asleep,
the questions run too deep
for such a simple man.
Won't you please, please tell me what we've learned
I know it sounds absurd
but please tell me who I am.
 
Now watch what you say
or they'll be calling you a radical,
liberal, fanatical, criminal.
Won't you sign up your name,
we'd like to feel you're acceptable,
respectable, presentable, a vegetable!
 
At night, when all the world's asleep,
the questions run so deep
for such a simple man...

Not at all !
 
Interesting that he may actually believe that creeping along in a lower gear at 19.5 mph is the most economical speed.
 
Real world driving for many years, tells me different.
 
He wrote: " I simply enjoy driving, a concept and practice that many others simply fail to understand."
 
There, he and I have something in common.
 
I most enjoy my driving in a relaxed manner. I also enjoy consistently beating the EPA ratings by a good amount. He may not!
 
Folks on these forums have described very different driving styles as well as very different mileage figures. To each his own.

Mileage data point Yaris 4dr auto 2006 by mkapoosta
Jun 10, 2008 (9:22 pm)

I am interested in buying a Yaris and recently rented one from a Toyota dealer in Portland Oregon. I told them I was interested in mileage and they suggested taking an older one since they improve their mileage with use (so said the rep.). I took a 2006 sedan with over 16,000 miles on it for two trips on the order of 400 miles each with a minor amount of town driving. I assume the tank was full of regular when I picked it up. The first tank came in at just under 43mpg. The second tank came in at 43.9 on premium. I drive at 55mph on the highway here in Oregon where the traffic is still relatively light compared to other states. This mileage seems high after reading some of the other posts. I imagine my highway speed is the reason for the great mileage I got since drag is a big factor and NOT linear with speed.

Excellent post!
 
Were the cars you rented Sedans or Hatch Backs?
 
You are right on about the wind resistance not being linear. Seems I read that the formula for wind resistance is:
 
The frontal area X velocity squared. R = A X V(2)
 
So a vehicle traveling at 75 would have a wind resistance of A X 5625
A vehicle at 55 mph would have a resistance of A X 3025
 
The increase in speed is 36% while the increase in wind resistance is 86% !
 
Chances are good that a lot of the poor mileage figures reported are from higher speed driving.
