Edit: Oh, now I see there is an X3 at the bottom of the list. Would be nice to see a Lexus 4RX non hybrid to compare.

Agreed. I don't understand how it's comparable to highlight a top end BMW sedan to a Lexus SUV? I'm not saying the BMWs aren't quieter, but it would be nice to see some BMW suv results and Lexus sedans as well for proper comparison.

So in light of what he said, i decided to pull up a simple noise test by Autobild, that indicated what the driving db (a test which rayaans has said would prove his statements). In that test the hybrid model RX 3rd gen was outclassed by both a more expensive 7 series and F25 X3 (cheaper then the RX and competes with the NX). If you still want claim something with support facts, I`m open to hear it.
Now granted this is not a 4h gen and the OP has even stated that the noise was not audible in his test drive (which leads me to believe this is probably a defect somewhere with the actual car).

Any updated on this issue OP?
Joined this forum as this is my first Lexus vehicle (RX350 2016).
Im having the same (very noticeable vibration) while moderately accelerating from a stop. I find it really annoying knowing how smooth and refined previous (older) Lexus RX350 models are. Heck! my 2006 130k mile Highlander is smoother that this. Don't know if its normal since I never test drove prior to purchase (wife did) and she doesn't seem to bother.
Let me know.

Thanks to Lubber to prove my point. See The initial response by Ravaans to my "bank vault statement", who drives a 3rd gen RX btw for reference, was that the OP can`t be be serious since " I won't accept that they have less noise than equivalent Lexus models simply because they dont. You can carry out a dB test and it'll prove that to you"

I've driven all sorts of cars and the Lexus models always seem to be very quiet inside. The BMWs have always had too much road noise from tyres especially since they use huge widths with sometimes rough tyres like continentals

I don't think the new 8 speed transmission is quite dialed in yet, maybe this can be made better with a software update. I have noticed problems in 3 areas.
1. Wiith moderate acceleration the car will hesitate slightly as the car upshifts too early and then the acceleration will kick in a little abruptly.
2. When driving at speed below about 60 MPH the car is in too high a gear and tends to drone a little.
3. When using radar cruise if I slow more than 2-3 MPH the car will down shift till it hits about 4k RMP holding the original speed and then very slowly slow the 2-3 MPH and then upshift.

Before I bought the f sport RX 350 I test drove a base model 350 and noticed this droning vibration that people have been talking about. However, I did not notice it at all on the f sport 350 so Could it be related to front wheel drive versus all-wheel-drive cars, and or possibly software programming as another poster mentioned? I believe both share the same eight speed transmission.

The sound is just engine noise and is not a concern to me. I do wish the transmission would stretch out the gear changes just a little when in normal mode but can live with it just fine.

If you read my comment I did say "... of the equivalent Lexus models".

Lexus' 8-speed tranny is still rough around the edges. For some reason they chose to develop their own instead of sourcing the absolutely excellent ZF. As a result:
- 2016 RX 350 have hesitation issues
- 2015 RX 350 F-Sport (8-speed) have the same hesitation issues
- 2015 RX 350 F-Sport (8-speed) is as slow and thirsty as 2015 RX 350 (6-speed)
- 2014 GS 350 (8-speed) is as slow and thirsty as the 2013 GS (6-speed)
Lexus has great ideas but sometimes the implementation is poor. 8-speed tranny and 2.0L Turbo, I'm looking at you!

Lexus likes to tune their vehicles for longevity over performance. So if they can add additional life to a component at the expense of shift experience so be it
