<<just a question hopefully someone can answer, i've read in many articles saying how great (and low) the aerodynamic drag is on the new c-class, and they state the numbers.>>

When the W203 showed up, warts and all, MB said it's Cd was .27. Then the W204 appeared and MB said IT'S Cd was .27. Guess what number the W211 has. You guessed it.
.27

I think their meter is stuck.
