New Myth Busters: Dirty Cars and Duel Efficiency - Page 4

Guess I misunderstood what they were saying. I flipped it on right as they were saying something about not much difference. Sorry guys.

So for those that watched the whole show - that drinking myth was great, wish I had known that back in the day! The dimpled car - would it be safe? and would it cost out the ying-yang to build? And who would buy it??

you know, im sure that some manufacturer may try to create something like this, it wouldnt cost too much to do this either, think saturn, they had plastic panels on the car, all plastic... all you need is a mold with dimples etc, easy.

but this is good news for everyone here!!!!! just put a link to the myth on your website, and prove it to everyone that a clean car gets better MPG, so a car with absolutely awesome slickness and protection is gonna get them better fuel economy, so come and get the detailing!

I could completely see a dimpled roof on a Prius in the near future if it actually made a difference. I doubt that would stop people from buying it.

As far as the dirty car argument goes, all I know is that in older versions of Gran Turismo, washing your car was meant to lessen the wind resistance of your car. So, it has to be true.

Didn't Lexus have a car with dimples on the bottom and the compared it to a golf ball?

Speaking of Lexus and dimples:

I stopped watching that show. Like they tested fuel economy on cars with a/c and one with the windows down and stuff like the truck bed up and down. They use two different drivers and there is just way too much human error in most of their stuff.

It seems to me that since only the front of the car contacts the air - and then mostly pushes it away from the rest of the body - that only waxing the front half of the nose clip would matter anyway, and not enough to make a difference. That's why the UPS planes did see a benefit - aircraft are much more streamlined and therefore have air in contact with the whole body and wings. Plus they go much faster. Super-sonic aircraft actually get hot from the air friction alone!

Riiiiight. Most race cars have terrible drag numbers. Their aerodynamics are designed to keep them glued to the track at high speeds, not to improve their fuel efficiency.

seen tons of mythbuster episodes, and they are very clear to state when something may give different results, but in terms of keeping things on an even playing table with the last mpg test, there was zero error possible by humans when they used a second gas tank for every run, did it at an already constant rate. not to mention that whenever they tested mpg the only test that they actually added in stopping, accelerating, etc was the one where it was based on how nervous/anxious/annoyed you were, compared to being calm, which could be different for any person.

i like the show, and from what i can tell they really cover all their bases for the most part.

I'm sorry, you missed the sarcasm in my post.
