I too didnt notice my road noise until I was on my way home after the purchase but the real eye opener was when I took my car in for service and got an base model jetta for a loaner, WOW what a difference the Jetta was wayyyy quiter then the Passat. Its pretty deflating knowing that my car is a step backwards over the jetta in terms of road noise and interior quiteness......pretty sad!
The type of road surface makes a huge difference. If your test drive was mainly asphalt roads then the interior is quiet, drive on concrete and those Hankook tires I had from the factory howl like a dying cow in a hailstorm.
I probably did 5 test drives to determine the cause of the noise and it was an issue for me until I drove the different road surfaces and knew the noise was tire related in my case.
Swapped the Hankooks for Michelin Primacy MXM4's and the interior noise reduced substantially. Less interior noise now than my previous Lexus IS350.

I may have to trade my B6 V6 for my new B7 TDI Premium when it arrives in August (if I don't sell it first). If the B7 has the Hankook tires on it, would it be a good idea to move the Michelin Primacy MXV4's from the B6 (with about 10k miles on them) to the B7? I would rather not pay money to replace the B7 tires with a new set.
I have not seen any 2013 B7s but if they arrive with Conti's, I will be pleased.

I have a lot of wind noise in mine, particularly bad on the driver's side. I purchased mine back in October, so there were very little reviews and even less that made mention of noises. I did go for a test drive in another b7 which was about 4-5 months newer than mine which had the exact same wind problem. I've called VW Canada and they were next to useless about the problem. The dealer can't see anything that is glaringly wrong, and considering another b7 was just like mine I can see how they chalk it up to the engineering of the car.
I'm to the point where I will soon pull the trigger on some heavier weather stripping and install it myself.
Well, I have just conducted a very un-scientific study on the cabin noise levels in the Passat. I downloaded a cool free decibel reader app on my Ipad. I compared the decibel readings from my Passat and my Civic at 40, 50, 60, and 70 mph and here are the results.
MPH Passat Civic
40 68db 72db
50 70db 78db
60 71db 74db
70 73db 78db
peak db 86 95
My only explaniation of why the civic went down at 60mph is that at 50mph there seemed to be a lot of road noise, then at 60 it quieted down and then the wind noise took over at 70.
Both cars were taken on the same route with the same speeds in the same part of the road.
The peak decibel reading were on a rough surface of the road.
The Passat has the continental tires.
Conclusion, The Passat with the continental tires is very quiet and as the speed increases the elevated noise levels come from wind noise and still remains relatively quiet. The Honda is a soup can on wheels. lol
It go down in the DM

I would make a bet it's the tires, there have been threads before and if you look at tire rack the rating for the Hank. tires are very low for noise.... (meaning bad).
I wish I would have know before I did buy, but on the road tests, it seem much more quite than the GLI I compared it too... I might call VW just to make a comment and see what happens, but I will probably switch out to contis or good year asymetrics when I get a chance.
And the observations are true, on some surfaces the Hank. tires are fine, but switch to concrete and it's noisy.
I did a little informal test this morning to measure road noise. Using my sound level meter (weighted to A) I measured road noise at 60 mph, windows up, climate control off, radio off, hand held and pointing slightly upward about 18" from the radio. Rough pavement hovered around 72 dba, fresh asphalt sections of road dropped 10 dba to 60-62 dba. I want to perform the same rest in my Q7 to compare as I have never felt it was loud.
Current: 2012 Passat TDI SEL / 2012 Touareg TDI Lux
Past VW: 2005 Touareg 3.2 / 1996 GTI-VR6
Past Other: 2007 Audi Q7 4.2 / 2007 BMW 328xi / 2006 Porsche Cayenne / 2003 Audi A6 3.0Q / 2001 Audi A4 2.8Q / 1998 Jeep Wrangler Sahara / 1991 Honda Accord EX / 1989 Toyota Supra
Using three different iPad sound level apps and averaging, our month old Passat (with the Contis) measures 60-62 db (A weight) on brand new freeway asphalt, jumps up 7 db on older but still decent freeway.
There is a stretch of road I want to test on that is really bad pavement.
