No idea, but I routinely see low-30s on the highway. It's mid-high 20s around town.
Is yours a DSG or a manual transmission?
Not sure if that was for me or not - but mine is a 7 speed DSG. It has much lower cruising RPMs in 7th than the 6MT or 6 speed DSGs did. The 6 speed has completely awful gearing for motorsports, but also the highest cruising RPMs in 6th. It's pretty lousy and one of the reasons I'm glad I got a DSG (though I was initially indifferent to them).
You can download that calculator I made here. You'll need to just save it to your own Drive or download as an Excel file.

In reply to flatlander937 :
Sidebar; How are you all getting 30+ MPG in these? My stock car, with 17" Vredestein quatracs (previously General AS05) on a flatland mostly rural commute at a consistent (40 miles, 5 lights) 60-65mph nets me 29 mpg every time...
I've actually hypermiled mine a few times and gotten closer to 40mpg when I had the stock all-seasons. (I make a regular ~120mi round trip 2x every other weekend - it consists of cruising at 65mph with 1 traffic light before I get to the highway, and only 1 when I need to get back on). I think a big part of that is because of the DQ381 as outlined above.
I will add: I RARELY do that anymore since it's way more fun when tuned. I have a lower boost map and I've found that keeping that one loaded for day to day driving has a HUGE affect on mpg - my full beans map will make 20psi at 2500rpm which only really requires tickling the throttle pedal when cruising on the highway.
To clarify further: If I REALLY want to drive nicely, it's not hard to get good mileage. Usually when leaving VIR I drive pretty restrained cruising home on Rt58, and while I'll be getting 35-37mpg (indicated on the dash, which is optimistic by a couple mpg usually) specifically from there to home... that gets averaged out with me hooning around and having fun to bring it way down.
Here is my actual mileage log since I made a sort-of "app" to track it on my phone - it's important to note that I've made 90 different tune revisions since March and I also work from home now... so literally the only times it gets driven is if I'm on my way to a race track, an autocross, or going out and doing 3rd gear pulls to fiddle with something on the tune.
You can see that after the one fillup after a VIR trip, I essentially drove the car home and parked it, then drove it all highway. 99% sure I wasn't truly hypermiling it (as the last time I did that wasn't anywhere near recent)... just going the speed limit and that's it (65 or 70mph here).
Edit: And here's a snip of right before I flashed a tune to my car for the first time - I didn't start logging until this point, but I had been getting 34-35 consistently without really trying too hard. I didn't think to start recording this stuff until I thought about tuning the car for reference:
