2012 Buick Verano – the quiet cousin of the Cruze on Driving the Nation

Noise Vibration and Harshness (NVH) are a real part of buying a car.

When you test drive a car Buick wants you to roll up, and down, the window next to a guy with one of those obnoxious leaf blowers. The noise should be deafening, but as the video shows, the noise is dampened to a mere irritant.

The Verano is a four door, no hatchback just a traditional trunk, compact sedan.

Verano Quiet Tuning features

Quiet-tuning systems, processes and components are built into every facet of the Veranos architecture. All are designed to block or absorb sound and dampen or eliminate vibrations.

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.
Liquid applied sound deadener is robotically applied throughout the body structure to both deaden and dampen unwanted noises and vibrations.
Sound insulation material between rear-body structural components 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 acoustic laminated windshield and 4.85-mm acoustic laminated side glass.
The engines intake and exhaust systems are tuned for quiet performance
Isolated brake and fuel lines prevent vibrations.
