That’s not always the case. It depends on the luxury car. I visited a Masarati dealer, and their selling point against a Model S was that the engine was loud. (“You want a car that that sounds like a car. You want to hear that purr and and feel that rumble. You can’t get that with a Tesla.”)

Same thing happens with luxury sports cars. I test drive Ann F-Type, and the damn thing comes a button to make your car louder. The call it “active exhaust” or something. It basically shoots gasoline into the exhaust so the car backfires. It’s basically rolling coal for rich people. The car was so loud, it was hard to have a conversation. I hated it.
