2015 is the same as 2017, just the facelift, why would you want to trade up?

It's also why the D5 and C8 have essentially been introduced on top of each other. The plan was they were supposed to be staggered, with the usual halo D series coming first.

FWIW, the big technical step for this sort of thing on D4's was probably circa 2013--Audi Connect, 360 camera, etc. Motor change from prior 4.2FSI happens there too. A few technology tweaks with 2015 facelift though pretty subtle. Facelift with 2015 was of course where more of the style changes occurred, including some improvement to the compromised trunk in the early D4's relative to D3's.
