What makes the Buick Verano so quiet?

Ever wonder how they made the new Buick Verano so quiet? well here's a list of some things GM took into account while designing it.

• Super-thick acoustic laminated glass in the windshield and side windows to block wind noise from entering the cabin.  
• 5 layers of thermal acoustic material in the headliner and dual-density carbon help keep stray sounds from being heard.  
• Even things that don't directly affect the interior, such as hydraulic ride bushings and isolated engine cradles that reduce vibrations from entering the cabin.  
• Engine and intake systems have been tuned specifically tuned for quiet performance.  
• Also the brake and fuel lines have been isolated to reduce vibrations.  
• Even the wheels have been designed to reduce road noise. 

Those are just of few of the things GM took into consideration when designing the Verano.
