Somebody needs to write a book about this stuff, but maybe it's too complicated and the people who know consider it a trade secret. I travel and rent cars a lot. It amazes me the difference between manufacturers. Some (like Dodge) seem to be able to make the base engine sound really good (even if it doesn't go) and others (like Ford), must save the good vibes for top end mustangs. I know BMW actually has some one in charge of "sounds" and is responsible for everything form the exhaust note to the "thunk" when you close the door. It seems like a lot can be done if you just keep trying.
