Roof bars and cycle carriers

[xtremist]

Well after a weekend of having roof bars* and cycle carriers on my A4, I can confirm that with just the bars and carriers on, your fuel economy reduces by about 7-10% and if you put a couple of bikes on the roof it's well over 10% :(

I guess everybody knew that anyway, but it's good to share :D
