Everything sounds artificial to me, because I wear hearing aids. That said the BMW sounds like a blender. For some reason the present generations of Hemi engines speak clearly through my hearing aids. These engines also provide tactile feed back as well, even when idling. To put that sound in an EV would be blasphemy.
Other engine melodies I have enjoyed are the 3 cylinder Saab two stroke (ring-ding) and also the old Kawasaki triple two strokes of times past. I will always remember the sound of the air-cooled VW type-1. I have driven a few, but never owned one. I did own a 440 cubic inch Chrysler T&C. It was a 1972 so it had a Holley carb instead of Carter. The intake roar was wonderful. The voice of that motor gave an aural warning when approaching illegal speeds. What sound ultimately stands out for me was hearing the USAC Dodge Chargers at the Syracuse mile. Those dual quad Hemi engines in those cars literally thundered around the track, very memorable.
The manufacturers will probably offer sound tracks for their BEVs the same way cell phones have ring tones. When there is no joy in driving anymore I will probably take the bus, but that isn't very entertaining since the two-stroke Detroit Diesels have gone away. Transit busses are now going battery electric, the only fun with those is watching the overhead chargers explode.
