i believe the nsu has a particularly low drag coefficient. aint got a clue about the others but id expect the caterham to be poor.

Pure guesswork but I'd imagine the Smart Roadster has a low drag coefficient due to a small front area. The Fiat 500 too, as there's no front grill to mess up the airflow.
The Range Rover and hummer have got to be the worst suerly? Or is it a red herring? |

Frontal area doesn't have a bearing on drag coefficient, as it's the relative drag created per area. So a small car can create less drag than a larger one, whilst having a higher drag coefficient.
My guess, from worst to best would be:
Caterham
Atom
Hummer
Range Rover
Mini
Spitfire
500
Smart
Caddy
NSU
Camry
Aston
I'm guessing the caterham/atom are somewhere around 4.5 and the Aston/Camry are around 2.8?

Id say the aston as it looks so smooth,i did think the smart but that front end looks like it got a step on it.

I pretty much agree with Robin, but I'm gonna go out on a limb and say the Camry is better than the Aston.
Also I like how the caption for the Mini says "Proper Mini".
