It sounds bizarre but I want to try it.
Fake engine noise is important for safety reasons. If people can’t hear cars, there are far more incidents. A lot of time and effort has gone into sound design for electric vehicles so people can hear when they’re accelerating, slowing down, etc.
The systems they’re talking about are sounds played over the stereo for people inside the car to think the engine is louder/sportier than it is. Pedestrians don’t hear it at all. I unplugged mine at the dealer before I ever turned the car on and have never been disappointed by the actual sound of the engine.
There is a small use case. If the vehicle was so well insulated you couldn’t hear the engine from inside, being able to hear the engine rev up and down would be beneficial for the driver.
Fords been doing it for a long time already, emulate engine noise through the speakers to make it sound peppier.
They also put plastic tubing and piping to direct the exhaust in the noisiest way possible. I remember when I heard they were doing the sound thing it was in conjunction with a plastic motor component that was effectively shaped like a saxophone that was supposed to produce a superior engine sound.
