Here is a video to give you an impression of the noise created by my Vectrix.
It's driving past the camera at increasing speeds, coasting (or regen braking) from left to right=downhill and going at a steady speed from right to left=uphill.
First pass from right to left at 30km/h, last one at 55km/h.
I plan to post another video for higher speeds.
Multiple other vehicles volunteered to participate as calibration examples in this video - none of them were harmed.
Details to help you through this most riveting movie experience:
35s : taking off
1:58min: regen-braking-by at 30km/h
2:47min : uphill at 30km/h
3:37 min : regen-braking-by at 35km/h
4:33min : uphill at 35km/h
5:10min : coasting at 40km/h
5:58min: uphill at 40km/h
6:40min: coasting at 45km/h
7:18min: uphill at 45km/h
8:05min: coasting at 50km/h
9:00min: uphill at 50km/h
9:38min: coasting at 55km/h
What do you think causes the noise?
Does your Vectrix sound like that?
Will it scare the Kangaroos away?
Can it be fixed?
