I just realized there isn’t acoustic glass on these gen 4’s… most of our older ones had acoustic glass… that’s why most of us are hearing excessive wind noise at the windshield… we don’t have acoustic glass this time around.

Why wouldn’t that be included? Seems odd.

The 'why' is money. Frustrating for a vehicle that cranks up to $50K.

I expect that the designers figured they had the airflow managed well enough to keep sound level tolerable with the cheaper glass. Acoustic glass s typically a 'work-around' for noisy turbulence...
