Sure you weren't in an A8? All AUDIs do look alike these days!Weird - I've driven both (2016 models) and the A6 felt substantially more spacious than the Civic. In fact, the Civic sedan felt only slightly bigger than our ILX, especially the backseat.
Keep in mind that even the A8 was Midsize, as is the Lexus LS. Only the extended wheelbase version A8 L achieved the 'Large' designation. So, since the A6 emblem and A8 emblem are practically identical at a glance, a 2014 A8 would have been larger than a Civic, but stll midsize.
AUDI dumped the smaller A8 in favor of only the A8 L in the U.S. in 2015. I suspect they did so in embarrassment upon realizing their standard flagship was actually smaller than Model S.
