One of the most defining aspects of electric vehicles is their ability to operate in near silence.
This video focuses solely on that aspect:
"BMW i3 Start up and Exhaust sound."
We think that title is meant to be rather comical. No exhaust = no exhaust sound and the start up is basically inaudible too.
There's one moment in the video that we believe captures the quietness of electric vehicles exceptionally well. You'll see/hear the BMW i3 drive by, followed by a big 'ol truck-ish SUV. The SUV sounds like a jet fighter taking off in comparison to the almost non-detectable amount of noise made by the i3's drive by.
