I too am not very about the fake engine sound, but even more I am annoyed that there is no option to turn it off. Bad Mazda! They should know by this time that customer is always right, and let us choose if we want it or not.
B.y the way, I tried driving with boot unlocked, (it's still secured mechanically, just unlocked, and there is no fake sound at all (except dash warning beeps that boot is not fully closed). It "sounds" Perfect!
Anyway, I wanted to share this video with you a bit more technical folks here. This is Honda Civic, but I would hope/assume something similar is also in MX-30? Separate unit somewhere under the dashboard that produces that's fake sound and could be just unplugged?
Oly if I knew what to look for (and how to open the dash panels)
