Yeah, and while that video is 5 years old, more recent videos (<https://www.youtube.com/watch?v=_jMcvb7she8>) still make it clear that hasn't changed (even if they try to mask it by playing music over it). I don't really think there's a way around it, though, electric motors spinning fast will just make that kind of sound.

That said, there's people who complain about F1 cars not sounding the same any more like they did back in the early 2000s (with the classic V10 engine), so even if the FE cars get modified in some way to change what they sound like there might be people complaining. Would be funny if for broadcast they replaced the FE sound with '60s V12 sounds, though.
