I saw recently that someone posted there was a engine noise radio in the car (searched and couldn't find it again). I sat in a parking lot with the car in park and my foot on the gas and revved the engine to 3500 rpm. I kept it there an ran through the econ, normal, sport and sport + modes, nothing changed in way of cabin RPM noise. Everyone in the parking lot looked at me as I was the dumb f**k that forgot to put the car in drive before putting it in drive. But the only noise difference I saw, was the red blush on my face. Seriously I do don't dispute there is technology at play for engine noise, but I tried today, I really did and I could not find it.
