I have spent a fair amount of time in Germany and Poland over the years and I can say there are a ton of European cars which seem to have fantastic aerodynamics when compared to a relative few here in the States. I can't say which cars are best aero efficiency wise, but I did see a lot of hatch style cars which followed the ideal template well and all seem to be offered with miserly little diesel engines as an option.
So why the heck doesn't GM or Ford give us the diesels here in the states that they do in Europe? My hunch is they're saving them for when they need to meet US Fuel Efficiency fleet standards in the future, then they'll be available so they can increase their FE average. God forbid we get a 52mpg Diesel Cruze now.

I mean who in America would want piles of crap like these that get 52 MPG (dripping sarcasm)

Hyundai..Gotta ask ya...you really think this Sonata Wagon would be a tough sell here in the States getting 54 MPG?????

I'm not sure about the rest of you, but I wouldn't be caught dead driving this Hyundai Elantra Wagon getting 62 MPG with sports car handling, 58 CuFt of Cargo, (compared to 70 CuFt in a Subie Outback or Honda CRV) and decent acceleration with a 124 HP engine.
