A friend of mine picked up a 2017 and I drove it for a little over an hour last night. The speedometer had a slightly different look; not better or worse, just a little different. The steering wheel is thinner, but not by much. The automatic shift stick also felt a little different, unless it was my imagination. The cabin is quieter. Not that I had an issue with my 2015, but the 2017 is definitely quieter, though there was a wind whistle at 100+ kph. The piano black trim is now a more practical matte silver. I can't say that I noticed the dynamic driving assist (or whatever it is called), but I wasn't doing much aggressive cornering.
