I posted these long comments over on Vortex but this thread is probably a better place. Not sure if people get upset at cross posting but to me it is all useful info. You can view the whole discussion or 2 of my posts below. Hope it helps those looking for a replacement based on interior space.

Cut and pasted from 2 posts:
1st post:
(first one was in reference to rear seat space comparing cars to a Mazda 6, a car that I really wanted to be able to fit the whole family in)
On paper maybe... Go sit in them. I am tall (6'5", normal for size 34" inseam) and if I have the seat all the way back I can still fit in the back with my knees just barely touching the back of the front seat in the Passat.
I have tried Fusion Hybrid/Energi models and Mazda 6GT, they don't even come close. I am squished in the back, knees pushing against the seats.
That being said, the front seats are way more comfortable in both of those than the Passat.
The thing I am working on now is if I can deal with scooting the front seat up a bit to a potentially uncomfortable position for when I have my kids in the car since dangling feet from car seats/booster seats take up a lot of space. Going to look into the Sonata PHEV which I had as a rental (non-phev though, normal base model) once, that was the only other car in this class that I *think* I remember being decently sized in the rear seat. Accord has decent rear space but felt I needed more seat travel but it just wouldn't go further.
If you are under 6'2" or have smaller inseam of 32" or less, any midsize will likely be fine.
2nd post:
Adding more to my post. Drove the 2016 Hyundai Sonata Hybrid Limited with Ultimate Package. Compared to the other cars I have tested as a replacement, this is the closest and is better in many ways than my 2012 Passat TDI SE w/roof/nav. Forget about spec sheets, this is the only other (Fusion, Mazda 6, new Malibu, 200) midsize that I can sit all the way back and still fit in the rear. The ceiling is a little low but since my kids are the only ones who will ever ride in the back, they will be fine for 10+ more years. I think the Accord was decent in the back too and have not tried the Camry.
I drove it on a similar route and conditions as I did the Fusion Energi, 6GT and my TDI. The Energi won because it had some charge in its battery to run electric only (I also ran it part way in hybrid mode since the main charge was low and only gave a mile+ of all electric) at 60+ mpgs, the 6 was around 28, my TDI around 33 and the Sonata Hybrid 40 mpgs. I have driven several Fusion Hybrids and Energis to know that without a charge and just in regular hybrid mode that I would have been around 34-35 mpgs. Could not take the Malibu Hybrid on the same loop but that car drove really nice.
Back to the Sonata, it is loaded. Around me these are MSRP of $35.5k but on the lot with rebates for about $10k under that. The plug ins are higher at $39k loaded but have seen quotes form dealers at $32.5. That is before Federal tax credit of $4,919 and Massachusetts rebate of $1,500. I think those are very competitive numbers even if I don't qualify for all rebates.
Compared to the Passat, the interior and exterior styling is different but very conservative, just like the Passat. There are some interior places that look cheaper but it really is a wash. The only one I disliked is the Sonata shifter, that does feel cheap compared to the DSG shifter. That is also the Sonatas other big plus, it has a real 6 speed auto instead of a CVT so it drives "normal". It allows a taller 6th gear so it is probably the only Hybrid that gets better mpgs on the hwy than city. That is a plus for the 3% of the time you want to be "sporty" and shift yourself (sport mode too, for what its worth) while driving in comfort for the rest of your boring commute in traffic.
Just get over the Hyundai badge, which after driving is pretty easy, and I think you have the best competitor to the TDI we all have enjoyed, and it is about $3-4k less than I paid 5 years ago and way more loaded than an SEL of anytime.
