Being an NA torque guy, if I were considering a TX, I would agree 100%. It's a big car (4700# -- dry) with the same little 4 cyl engine (with a hair drier) that they use in the NX, that's about 800# lighter than the TX. If I'm not mistaken, I believe the only V6 TX will be a PHEV. I have driven an NX loaner car, and in typical small displacement turbocharged engine fashion, when you stomp on it, there's really nothing, then the turbo kicks in and all he77 breaks loose. It's OK on the highway, but stop and go would drive me crazy. Can't imagine a 2-1/2 ton car with a 4 banger, NA or blown.

In terms of NVH, the all the doors were open and the sales guy slammed the back door when he got into the second row while I was in the 3rd row testing the survivability (I pleasantly survived). The body DIDN'T shudder at all. It felt like a tank The GH on the other hand, felt like overcooked mashed potato in comparison. The car was quiet, the suspension was supple yet handles really well and drives smaller than it really is. Overall, a Sienna is wider and more spacious, therefore a more useable vehicle. I would choose this over the Sienna if I didnt have 2 car seats to deal with limiting access to the 3rd row.

My question is how are all these complex engines going to perform in the real world when these things are loaded down with gear, towing, etc. over the years. I hope to be pleasantly surprised.

Well the hybrid version of this engine is going into the new LC. And if the past still holds true, it should last 25yrs or 250k miles. The battery probably wont though, but we all know that.

Having driven the hybrid max grand Highlander, the hybrid helps with the turbo lag on the 4 cylinder but I feel the V6 PHEV TX 550 will be the best overall driving experience

They'll be fine. Bear in mind vehicles like this are not heavily used, people don't tow with them. They drive 4 people around and luggage and all and thats it. This is basically a minivan

They will be "fine" with the V6 in the Colorado mountains. I just hear the engine screaming for mercy when going up some 13,000 foot pass. No way would I want a 4 banger here in Colorado with the weight of the 550. My wife has a Rav hybrid, and it has all it can handle with the weight of the vehicle and the grades it has to climb. I believe the 4 banger is probably OK on flat land. By the way, I think my 2018 450 is use quite a bit, as it has 75000 miles.

I haven't driven them yet, so I'm reserving judgement for now.

Yup lol
The hybrid solves this issue, Lexus with the 3.5 though have lazy throttles which causes a very annoying acceleration delay anyways.
