thanks a lot for the info, it has proved very helpful:bigsmile::bigsmile:Here's a manual I scanned a while ago for a someone else who asked the same question.
Though searching internets is probably easier, just check your findings by cross referencing with other websites. The other way is to find the manufacturers original specs. A vehicles CD is normally quoted somewhere, Vauxhall used to make a big thing about it in their ads many moons ago.
I had this doubt. Cd*(Frontal area) is a better measure to find out how one's car fares in the aerodynamics
Frontal area is not a very good indicator of the aerodynamic performance of a vehicle. The SHAPE of the vehicle if far more important.
