I had two test drives today: Macan 4 without insulated glass and a Macan Turbo with insulated glass. I drove exactly the same route, and found it hard to hear difference. If speed is below say 40 miles, the car is super quiet. Driving on the motorway with 70mph was noisier than expected...
I would think that the difference with or without laminated glass is most noticeable on the motorway as wind and tyres will make themselves heart. I don't care about city driving.
