In case anyone was curious, the NX (450h+) has dual pane laminated glass (AGC Lamisafe) for the front passenger windows. It is also known as acoustic glass. For those unfamiliar, a dual pane glass window consists of two layers of glass bonded together which results in a thicker, quieter, and stronger window than single pane glass. Laminated glass is also effective at blocking harmful UV rays. You cannot tell any difference looking through the glass but if you roll it down you can see the separate layers at the edge and it is thicker.

The rear passenger windows still uses single pane tempered glass (AGC Temperlite).

Lexus and other luxury manufacturers have used dual pane laminated glass on cars for years but typically only for higher tier models and/or certain packages. As far as I know this is the first time the NX line has it. I do not know if all NX trims have them but I can confirm the 450h+ does.

 

Curious. Can anyone confirm if the Luxury model NX also has the laminated glass?

 

I believe all versions do. Verified that the 350h includes it too.

 

That is awesome that there is dual pane glass now.

 

I wonder if it’s just the models with rhe CVT transmission to mask the noise those emit vs the turbo with 8 speed.

 

You really think that, unbelievable

 

In my current Toyota I have emergency hammer in case I would need to break my front side glass (for example in case my car gets submerged into the water). So when i was reading th manual, I noticed that there was a note that laminated glass cannot be shattered with emergency hammer:

 

Well Lexus did say they wanted to address concerns from previous NX owners and one was the noisy cabin.

Here’s an article just for you…confirms that it isn’t far fetched to think Lexus decided to use acoustic glass to help with noise. This reviewer describes the noisy engine from the 350h.

“Annoyingly, it’s a rough and noisy four-cylinder, against the character of this otherwise refined car. I like to drive briskly without my passengers noticing. But in the NX the soaring revs and grumbly noise make it obvious every time I flex my toe.”

Acoustic glass can and will help mask this noise.

 

Have you ever driven or owned a hybrid? They are actually very quiet. I have a 2020 Avalon Hybrid limited which is basically the same engine as the ES300h and it is very quiet. I guess during hard acceleration this is some minimal noise. I am not sure which NX you are leaning toward but non will probably satisfy your needs; all too slow or too loud.

This whole thread is starting to get too pedestrian and picky about things that are truly insignificant or a simple read the manual answer.
The acoustic glass is going to lessen the noise from the outside, but it will do nothing to lessen internal noise from the engine through the firewall.

Peace and quiet to all NX owners and future owners YMMV,

My NX450h is incredibly quiet and vibration free. There’s an absence of engine noise….with 302 horsepower working for you. Separately, no wind noise, no rattles from any location. Now that the infotainment system was stripped down and re programmed by the dealership….it’s really rather perfect.

 

Awesome

 

did you find any solution for laminated glass? i always carry a hammer, but now the lexus i got has laminated glass and i'm looking for options

 

I have no solution for this. But knowing this in case of the emergency I will try to break glass in back seat windows.
