I don't see anything major in changes to the 2017 Avalon, I wonder if 2018 will be all new, different, better or more of the same?
They will fall behind real quick if they don;t do something. Many of the trade publications, have the competition ahead in many areas.
CR, has the Chevy Malibu as more comfortable and quiet, and they think the Kia is also a great choice against the Avalon
The New Lincoln is sweet looking, as is the All New Buick Lacrosse, They aren't Toyotas, but still they are involving.
Total units sold is dropping a fair amount (10,000+- YTD). I wonder if it's because of all the bad press from 2013 - 2015 models, or if the public is just looking for something else nowadays.
I'm sure some of it is, they last so long, I'm also sure some has to do with trade-in value to get a newer, smoother riding car, is not something most folks can take the hit on.
I for one will be waiting to see what they do, if anything,
as I'll have 75,000 - 95,000 miles by then, and looking to trade (Maybe

)
I know it's an old thread, but decided to leave my opinion on the subject anyway.
I wasn't planning to buy an Avalon. I liked the gen 2 and gen 4 Avalon for their looks and ride, but wasn't very impressed by the 2013+ because of very "camrysh" ride and not exactly unique design.
I drove a lot of different cars over the past year and just before buying an Avalon drove a 2017 touring Accord, Malibu (and sat in Impala), Taurus (yes, I know, but I wanted to try it anyway), a used Genesis, 2015-16 ES350 and 2015 GS350- the car that was on top of my "My next car list".
Coming from a Camry XLE V6 I was looking for more comfort, quiet ride, nicer design and better than average reliability.
I have no love for the 2015+ Camry and the new 2018 Camry looks weird and unbalanced imo and has low sitting and less than well thought interior design and materials, so the Camry was out for sure, even though I'm a Camry man.
After driving my buddy's 2017 Avalon I was very surprised how nice and plush it drives. Nice seats (I just want to add spacers under the front of the seat frame to increase the cushion pitch), a very nice and clean sounding stereo, very smooth acceleration (my Camry was a bit quicker, but had more explosive and jerky acceleration) and nice steering. Yes, there are some shortcomings and some interior materials can be better, especially compared to the ES and GS, but considering the price and discounts, the Avalon was by far the nicest riding and smooth vehicle around $30-33K.
I wish the Avalon had a folding rear seat and less chrome outside and especially inside, but if someone looking for the comfort, the current Avalon is a great choice. My boss has a new style $60+K E400 and he admitted that the Avalon rides more comfortable, plusher and quieter.
as of today I see only 3 big issues with the Avalon:
1. very weak low beams and unfortunately the OEM projectors can not be replaced with something else.
2. weak brakes, better pads and rotors should cure it.
3. too much chrome inside.
There are a lot of areas where Avalon can be improved and modernized, but I'm afraid if the Avalon's would get any closer to the Lexus, it sure would affect the price tag and even less ppl would consider an Avalon. Imo the Avalon should stay at "the nicest Toyota" level and not to try to become "a cheap Lexus".
Exterior wise, a large cat fish mouth looks pretty good on the Avalon, actually the whole front end looks very good. I would eliminate the chrome belt around the grille and make the step at the bottom of the headlights a bit sharper. I prefer solid C-pillars with no windows like on the 2005-12 Avalon, well, at least they are real windows and not some fake plastic windows like on the 2015+ Camry

and change the roof-C pillar line to more sedan like silhouette. The 2013+ hatch like roof-C-pillar- trunk line looks smooth and maybe more modern, but imo take away charisma and charm of a large sedan.
