I think more recently BMW marketing has started to employ politicians, and I’m vary wary about what it claims.

I seem to recall the G45 being pitched as a more luxury oriented product during late development, when model range info was released, but if anything, it’s the opposite.

The original group press releases was more specific -

Well Here’s hoping the front side windows are acoustic glazed for the Uk release… highly doubtful.. but fingers crossed!

Anyone who's already seen European vehicle checked if it has acoustic glass? Its so strange that none of the reviewers mentioned it.

Most reviews don’t even know the detailed spec of the car, let alone comment if something is missing. It isn’t helped that most are press cars, so time is short.

I’ll be at my local BMW during the next few weeks, so will take a look myself if there’s a car available.

Acoustic glass isn’t listed on the Uk build spec order sheet, like it was for my G01

Better hold tight to your M-colored seat belts!

What is the most noticeable difference between acoustic and none acoustic glass? The general road noise or wind noise?

Both according to BMW, and that’s accurate based on my experience.

I find the interior quiet at motorway speed, and I’m running on 21” RFT with M mirrors.
