Congrats on your A7. I'm sure you will love it. I have a '13 A7 Prestige...rarely does a week go by that I don't get compliments from strangers.
By the way, if you don't want to put your bikes in the cargo area, you can use a bike rack if you get a set of "hatch huggers".
I have a Saris bike rack, and to make it work with the hatch, I got a set of these: http://www.saris.com/product/hatch-huggers
The link includes a video to show how they work.
