Quiet tuning

Buick Verano delivers the library-quiet driving experience for which Buicks have become known. Quiet-tuning systems, processes and components are built into every facet of the vehicle's architecture. All are designed to block or absorb sound and dampen or eliminate vibrations.

Hydraulic ride bushings, for example, and an isolated engine cradle reduce or eliminate vibration pathways that could be transmitted to the passenger compartment. Similarly, a number of noise-reducing and noise-cancelling technologies are employed throughout the body structure, including:

The steel front-of-dash panel is sandwiched between two damping mats
Nylon baffles are used in various hollow portions of the body structure and filled with sound-absorbing foam that expands when the body enters the paint oven
The headliner comprises five layers of thermal fiber acoustic material, including a premium woven fabric on the visible outer layer
Patches of sound-damping material are applied strategically throughout the body structure and melt into place when the body passes through the paint oven, allowing the patches to follow the contours of the sheet metal below
Sound insulation material between rear-body structural components that is made from recycled denim
Triple-sealed doors that feature fiberglass "blankets" serve as water, airflow and noise barriers. The doors are also beta-braced, meaning they close with a solid, precise sound and no resonance
Optimized windshield and side glass for quietness, with 5.4-mm-thick laminated windshield and 4.85-mm laminated side glass
The engine's intake and exhaust systems are tuned for quiet performance
Isolated brake and fuel lines prevent vibrations.

Even the wheels and tires contribute to Buick Verano's quietness. The standard 17-inch aluminum wheels are manufactured in a unique way to enhance quietness, while the tires minimize road noise.
