Default What is the drag coefficient (c/d) of the B5 S4 ??

While discussing aerodynamism of cars, I was asked what was the c/d of the S4... Must be around 0.30 but what is the exact number? Don't see s%$/ in any tech paper...

Archives doesn't seem to talk about it... and it's kinda of impossible to search for "drag" since it does include "drag racing" "drag car", etc...

Default The B5 generation was not designed in a wind tunnel if I remember correctly, so that data may not be

available.

Remember, this car was introduced as an A4 around 95 maybe even 94 in germany, so this engineering is at least 10 years old (maybe a little more)

Did you try searching for "drag coefficient"? It's there.
