My Personal Experience: A Tale of Two SUVs

In the world of full-size SUVs, the experience can vary dramatically, as I discovered firsthand. I had the opportunity to test drive the Mazda CX9, one of the models featured in this guide.

The quietness was remarkable, so I sometimes wondered if the engine was even running. It was an experience that genuinely highlighted the luxury of silence in a well-designed vehicle.

On the other hand, I also had the chance to drive the Nissan Armada, a full-size SUV not included in this list.

The contrast was stark.

During a trip from Staten Island, NY, to Lake Placid, NY, covering about 6 hours and 300 miles of mostly highway driving, the noise level was noticeably higher.

Even at lower speeds of 35-45 MPH around Lake Placid, the vehicle was, I can say, “loud.” LOL

Here’s the visualization representing the noise levels (in dB) of the selected SUV models:

• Cadillac Escalade: 67 dB
• Lincoln Navigator: 68 dB
• Mazda CX-9: 70 dB
• Ford Expedition: 71 dB
• Jeep Wagoneer and Wagoneer L: 72 dB
