Diesel heretic here. Wearing the nomex...
In advance of selling my 2014 back to VWoA, we just purchased a used 2014 Avalon Hybrid Limited, 12k miles, $47k sticker in 2014, paid $28.4k. It'll cost me $1.5k more than what VWoA will give me for my 2014 NMS Passat with 60k miles.
I've driven 280 miles in and around the Dallas region, in traffic, some 75-80 mph cruising, probably 40/60 C/H.
Computer says 42.6 mpg. Won't know actual mpg figures until I refill the tank.
Totally different class of vehicle, virtually identical interior/exterior dimensions. ALL the available bells and whistles (vented seats: WOOHOO!), 200hp, CVT (gag!...but almost as responsive as the hesitant and sometimes confused DSG!) Trunk is smaller, but not by much, 14cf vs. 16cf, BUT, it's deeper, more square, appears to be more useful.
Oh, and the Avalon no longer drives like a Japanese Buick. It's not German by any stretch, but not a huge step down.
Go ahead...hate on me for going hybrid (trading the hyper-engineered but fragile CR TDI for UBER-engineered but time-tested, reliable Toyota hybrid!).
