This was for the Evo7, but gives you a rough idea.
This is from a German magazine called Sport Auto. THIS is how you test cars! None if this "0-60, 1/4 mile, skid pad, 60-0 brake" and that is all the testing we do. This magzine actually does windtunnel testing as well as the usual measured tests. I think I have a longterm test of the GC8 (Impreza Turbo) as well as Audi RS4 in one of their issues.
