We all know that sports cars usually have very good aerodynamics, but what about more pedestrian models? What regular cars have a a low drag coefficient? Prius? B5 Passat?

Loads of clickbait listicles with this info out there. Here's one of the less obnoxious. Just don't try to read the text, it'll cost you IQ points.

Short version for current production cars: Mercedes CLA, Audi A4, Priuseses, Teslas, BMW 5 series and amazingly, the Alfa Guilia. There are others, but I'm going to make you click the bait.
LS400. Really low CD. Like the same as a Europa low.
Dr. Hess said:LS400. Really low CD. Like the same as a Europa low.
Whole lot more frontal area, though.
wasnt the C5/C6 supposedly really good?
How about a Honda Insight?
What’s the question again?
I dunno.
Porsche 924
cd = .32 (or .31-.33 depending where you read)
frontal area = 19.37 square feet
Pretty fantastic for 1976

Yeah, I've done teh maths. Whole Lot More HP too.
You guys made me look it up, cd for a 2003 Accord Coupe is 0.29.
Which made me look up the Europa, which is also 0.29.
Again, frontal area, but......not bad.
Stock C5 Corvette? 0.29.
First gen Honda Insight, 0.25.
2018 Prius, 0.24.
2010 Volt, 0.28.
This is fun.
In reply to DWNSHFT :
beat me to it. I read this post on my phone as I was standing next to my 924S and thought to myself: "this"
Then looked over at my e30 and thought to myself "definitely NOT that..."
The W124 Mercedes was down to 0.28.
My Ct200h comes in at .29. Not as good as the Prius, but it’s a flat trade for a better looking car.
My my spyder is .35. Must be those big ass headlights.

Ok, so we listed Cd, but you also asked about aero. Do you also want to know what factory cars have good downforce? If not, I would!
GM EV-1 0.19

Perhaps not regular, but, WOW
924 and Europa aren't really "regular" cars. Luxury models stretch regular, too.
I submit the Hyundai Sonata Hybrid, at .24 Cd
Nobody looked at that link of mine, did they? 
Mercedes CLA and current BMW 5 series - 0.22. That's just astounding, and those are normal cars. Surprisingly, the GTR is 0.26 and the BRZ is 0.27. The Europa/LS400 are around 0.29.
I've gotta offer up the Subaru SVX.
Cd= 0.29.
In European markets it was 0.285 (larger under tray)
That may not count as a "normal car", but it did have a back seat, and was a mainstream production vehicle.
https://en.wikipedia.org/wiki/Hyundai_Ioniq
Hyundai Ioniq has CoD of 0.24
Saturns always “seemed” like they were pretty aero friendly. Whatever type this one is:
just for fun.. looked up my Disco. .44. I think a brick is slightly more aerodynamic
In reply to Keith Tanner :
The cla with amg bits is s good looking car. Like a baby cls. Anyways, Mercedes Sindelfingen wind tunnel is pretty cool.
I looked it up. A smooth brick has a cd of 2.1
Surprisingly the Lamborghini Countach (1974) has a cd of .42. So your Disco is almost as aerodynamic as a lamborghini! 
Does an old Tatra count as a regular car?
1938 Tatra T77
Cd = .212
