Who has the quietest brand?

The dB reading I have is lower than what C&D published for the Navigator, that was the point of what I said. the dB reading doesn't tell you definitively which car will feel quieter inside, and my experience having driven all of these cars they're all very similar in regards to interior noise. The Navigator is very quiet, but coming from a very quiet car and having owned and driven many other very quiet cars, it didnt strike me as unusually quiet, or any quieter than what I drive every day.

64 is pretty quiet. I have yet to see Car & Driver report a lower score, the 64 is for the reserve label and not the regular model. I am thinking Lincoln is quietest mainstream brand across all models.

I've driven the Navigator, Continental, MKZ and MKC. The only one I would comment as being impressively quiet is the Navigator, so I wouldn't say that as a brand at all.
At one time I would have said it was Lexus, but not today. As far as Buick, the Lacrosse is quiet, the Enclave is pretty quiet but not extraordinarily so. Modern Volvos are very quiet.

There is nothing in the Navigator's literature that would suggest the Reserve would have more sound deadening than the lower trim. Why wouldnt they market that as they do in other vehicles?

The Verano, BTW, was also surprisingly quiet (its roof alone had five anti-noise layers in it, in addition to triple-sealed doors, double-paned glass, and special trunk insulation...but the 18" 45-series tires bumped and thumped over road imperfections, especially in the winter when the shock fluid was cold and the tire-rubber more stiff, and the Ecotec four made more noise than the Lacrosse's V6 when accelerating. Trump (before he ran for President), actually did Verano promotions extolling its quietness and how much he liked the car. I loved mine, even with its faults (and even with the Ecotec's oil consumption LOL)
....it was the best-driving compact car I ever owned.

Those differences are also attributable to the road surface, the person or people in the car, the time of day, the temperature outside, weather, model and brand of tires, etc. If you drive around and use a dB meter (which I've done) you'll see how easily it can me impacted by several dB. Thats my point, you cant use a few dB between cars or tests as proof one car is quieter, its a measure that is near impossible to reliably take the same way and under the same set of variables every time.

For what its worth, from Car & Driver at 70MPH:
2013 Lexus LS600h 64DB
2018 Lincoln Navigator Reserve 66 DB
2013 Lexus 460 F-Sport 66DB
2019 Lexus LS500 F sport 66 DB
2019 Toyota Avalon Hybrid 67DB
2018 Buick LaCrosse 68DB
2019 Toyota Avalon 68DB
2019 Lexus ES300h 70DB

Was that on the gas engine or the electric? 
Or don't you know? With the electrics, you will probably hear less noise from under the hood, and more from other sources.
I sampled a new 2019 Avalon last week (base XLE model) with the easier-riding 17" 55-series tires, and, to my ears, it seemed almost as quiet as the Lacrosse's 18" 50-series...perhaps just a hair noisier. I will seriously consider an Avalon XLE, even with its cave-entrance grille and ski-ramp dash, if Mary Barra and her cronies won't make new Lacrosses available in the future.

You can certainly challenge the results and dispute them if that is what you want. For all we know, Car & Driver could be using the exact same roads for the test which is likely a very good possibility. Motorweek seems to use the same test track, so does CR with theirs. That being said, they measure the DB reading at the drivers ear height. Its nice to see Car & Driver as well as Motor Trend post interior decibel data which is difficult to find. This is published data which is nice to see, Car and Driver also publishes the weather data for the test and which track the test takes place. Other data such as tires and other things are reported. Most tests are done at test track CPG, whatever that means. They also do three test measurements.
So, don't expect a car that reads 64dB to feel quieter than one at 66 dB. Thats my point.
Any car under 70 dB is very quiet.
2018 Lincoln Navigator Reserve 66 DB
if Mary Barra and her cronies won't make new Lacrosses available in the future.
Even with the Lacrosse, which is indeed quiet, road surface can make a difference. You will definitely hear more tire-noise on porous/grainy asphalt or concrete....but, on traditional smooth asphalt, it is like a rolling tomb. You can hear some faint noise from the DI injection underhood when accelerating. I doubt if it equals the LS460 or Mercedes S550 in quietness, though....but you're talking 2-3 times the price.

No conclusions have been drawn. A discussion has been had. That was the whole point of the thread. It’s nice to see the Car & Driver uses what appears to be the same test track. Looks to me like Lincoln is the quietest brand, IMO. Disappointing that Lexus has a few models with about 70db reading and one of those cars is about $100K. As for 64, I will need to double check later.

This is whats frustrating. You can't agree or disagree with facts. What I have posted about sound pressure readings (dB) and how they translate into perceived loudness or annoyance of sound vs frequency is fact, you can look it up yourself and educate yourself if you would like to.
.its nice to see Car and Driver post their date, I think Edmunds used to.
