But there are cars that used "emulated" exhaust sounds via the sound system - I know BMW and Porsche do this. I think it's ridiculous. Either make an engine that sounds good, or don't, but don't make fake sounds just for the passengers to hear.@mr.niftie...if you read each post in this thread, you will recognize the engine sounds via the radio was an admitted misunderstanding of an option description. The audio system does create noises of the opposite polarity to suppress engine sounds and other interior sounds using the ANC (Active Noise Cancellation).
