About wind resistance...

[Kal-El]

Interesting post.

Of course there's many variables that create endless mpg possibilities.

What kind of wind resistance is this considering? A calm non-windy day?

How about the direction of the wind? Is it a heavy noise wind? Tail wind?

Then it all depends on the gradation of the road.

There's a million variables to fuel efficiency.



And then people go and complain about not getting EPA estimates, LOL.

I can tell you what I've been dealing with the last couple of days. Cross-winds. Strong cross-wind from the north as I traveled due-west on I-40 on Friday... and strong cross-wind from the south as I traveled due east on i-40 on Saturday. Except that I think it was a direct head-wind for a while on the way back. It's hard to tell in the Yaris.

But yes, wind is a very complex topic, which makes a huge difference even when one doesn't notice it.

What's the Yaris' "Side CdA", I wonder? Or 45 degree CdA? Yes. It gets very complex very quickly.

In my post, I implicitly assumed the simple case of still air and a moving car.
