Maybe not. However, I was extremely surprised when driving the 2017 90D on a noisy rough concrete freeway at 65 mph and got sound readings of 70 dBA.That is about where the 2009 Escalade was and is quieter than the 2012 MS P85 at 76 to 78 dBA or the P90DL MX at 74 to 76 dBA.
Given that decibels are logarithmic, isn't 70 dBa vs. 78 dBa a significant difference? At least this confirms by guesstimate that the 2016 X is as loud as my 2013 S.
