When evaluating SUVs, a quiet cabin often tops the list of desirable attributes, as it greatly enhances comfort, especially on long journeys. To determine the quietest SUVs, we conducted a noise test at 70 mph, using a consistent microphone placement to ensure accuracy. Understanding the decibel (dB) scale is crucial, as increases are logarithmic rather than linear. For example, a jump from 30 dB to 40 dB represents a tenfold increase in noise intensity, making even slight differences in dB numbers significant in real-world driving.
Below, we rank the 10 quietest SUVs for 2024, ranging from the Kia Telluride at 60 dB to the class-leading Audi Q8 at 56.2 dB. These models showcase varying degrees of engineering refinement aimed at minimizing cabin noise, each bringing unique strengths to the table.
