These results are interesting but unfortunately not too helpful. We don't know what sort of road surface was involved or where the measurement was made. Assuming that the Edmunds results are consistent between cars, the touring Z was about 5 db louder than the Mercedes. That would be around 25% more noise.
What I was hoping we could do is get the
difference in the same car of the noise level before and after sound treatment. With that data, members could compare solutions versus cost, etc. and decide what, if anything they want to do.
