> [@Clean Baldy](#): > > what are “good” and “bad” numbers? cd is the coeffcient of drag. Lower numbers mean less drag. A is the frontal area of the car. Bigger number means a bigger shape presented to the wind. Downforce and lift should be self-explanatory. I \<3 this stuff. An F-4 fighter has a cd of .022 😛 ---

![http://aviationfans.com/images/4forces.jpg](http://aviationfans.com/images/4forces.jpg) Just sub out the Sukhoi for a ZR1 (although the lift arrow would be pretty tiny) Reducing lift requires downforce, and downforce adds drag. Less downforce = less drag = higher top speed. Both the 997 911’s have the best cd. ---

> Otsuka’s team of more than 2,000 engineers also included aerodynamics specialists who managed to cut the 2010 Prius’ coefficient of drag – to just **0.25** from 0.26 for the '09 model, which already had one of the lowest CDs ever for a mass-produced car (a bullet by comparison, has a drag coefficient of 0.29).

wow, stock honda del sol is .35 cd and 0.663 cdA. More here: [http://ecomodder.com/wiki/index.php/Vehicle\_Coefficient\_of\_Drag\_List](http://ecomodder.com/wiki/index.php/Vehicle_Coefficient_of_Drag_List) Need to convert from f^2 to m^2 though. …hrm, actually that list there has the NSX at .57 while the one posted here has it at .60 I guess the accuracy might be slightly off. ---

You can’t look at cd alone, unless you want to have retarded bragging rights. Have to look at it with downforce as more downforce = more drag. ---

I’d assume that something like a truck or awkward shaped car like the dell sol can have a lot of drag without actually having downforce, correct? or is drag always broken down into downforce/lift?
