'60 Minutes' admits error in dubbing noises over quiet Tesla electric car

31. Audio redubbing is pretty standard in television, movie, and video production.

Adding background bird chirps to an otherwise silent shot of a forest, road noises to a freeway shot, etc. Virtually every foot of prerecorded video that makes it onto television crosses the desk of a sound engineer first, and that persons job is to modify and enhance the audio in a way that makes it seem more "appealing and immersive". Every door slam, every footstep, every windy rustle through the trees is modified, enhanced, or just outright replaced. Even if that means completely faking sounds.

Replacing engine sounds is pretty standard. You've never heard a car engine in a movie or TV show that wasn't modified before broadcast. If the car is too quiet, you isolate the engine noises and increase their volume. If they can't be detected, you dub in a new one.

In this case, after looking at the dubbed footage, I can almost guarantee that the audio was placed by an engineer trying to "enhance" the shot.
