Washing and waxing that thing is going to be a big pain in the ass.

clay is not car paint. I wonder how much of a diff that would make.

As for the full scale testing, what exactly did they do that would undo the fuel economy savings that they saw? Beyond some math error or issue with the fuel system that caused some unaccounted gas in their calculations I don't see how their number could be 11% off. No matter what you think SHOULD happen, you need to explain what DID happen.

Yes, the mythbusters aren't the most scientific, the set up stunts and do special effects. However, I don't see a way to explain away the difference in the full scale test besides a gross error. While they aren't scientists I think they can probably handle putting a fuel cell on a scale.

Assuming that the 11% increase in fuel economy was brought about by an 11% decrease in drag... that means the body drag would have been reduced by 33%.

wat? Also there could've easily been a higher or lower reduction in drag and the reason for that is because of the BSFC of the engine depending on the load.

Hmm, that hail damaged BMW is looking better
