Aerodynamic "regular" cars

I just found out about the new Merc CLA's aerodynamic figures: the CLA 180 BlueEfficiency has a Cd of 0.22, and a 2.21m^2 frontal area giving a CdA of 0.4862.

M-B seem to have spent quite a bit of time and effort making the underbody more efficient - the car has suspension covers, baffles and all sorts of stuff.

The Cd factor of 0.22 is really impressive. More info over here

Yeah, well back in the day Calibras were so slippery they had negative drag.

When you parked them up they created wind......

Cd is just part of the picture. There's pitching moment coefficient and obviously coefficient of lift. I'd be more concerned about the latter two in a performance car on the road.

So aerodynamic they made a special version
