Cars can synthetically reproduce engine sound through the audio system.

Evidence

I coined the term schizophonia in The New Soundscape intending it to be a nervous word. Related to schizophrenia, I wanted it to convey the same sense of aberration and drama. Indeed, the overkill of hi-fi gadgetry not only contributes generously to the lo-fi problem, but it creates a synthetic soundscape in which natural sounds are becoming increasingly unnatural while machine-made substitutes are providing the operative signals directing modern life. — Schafer, Murray R, The Soundscape- Our Sonic Environment…, 333 (#exemplifies, via linked claim)

We have split the sound from the maker of the sound. Sounds have been torn from their natural sockets and given an amplified and independent existence. Vocal sound, for instance, is no longer tied to a hole in the head but is free to issue from anywhere in the landscape. — Schafer, Murray R, The Soundscape- Our Sonic Environment…, 329 (#expands, via linked claim)

Throughout the history of soundmaking, music and the environment have bequeathed numerous effects to one another, and the modern era provides striking examples. For instance, while the internal combustion engine gave music the long line of low-information sound, music gave the automobile industry the pitched horn, tuned (in North America) to the major or minor third. — Schafer, Murray R, The Soundscape- Our Sonic Environment…, 405 (#corroborates, via linked claim)
