After reading my christmas pressie-the history of the evo,i was surprised to see the Evo 6 had a Cd of 0.30 which is surprising seeing as the front end is big flat lump of scoops and intercoolers,i know this figure was a good benchmark years ago but was wondering if anyone knew what there car was for comparison.
Boring i know but i'm curious :roll:

I dug this list up some interesting entries
0.7 to 1.1 - typical values for a Formula 1 car (downforce settings change for each circuit)
0.7 - Caterham Seven
at least 0.6 - a typical truck 0.57 - Hummer H2, 2003
0.51 - Citro

i believe as standard the celica ST165 is 0.29
as an aside, does anyone know a website which details aerodynamics and downforce etc in a semi-laymans manner? those who have seen the rear "spoiler" on my car will know why i ask!

mk4 supra turbo is 0.31 with the spoiler on
