> 59kW/kg

At this point why don't we get rid of the k prefix and write 59W/g?

Edit:

I was half joking, but various answers mention kW being standard for motors, kg being the SI unit for mass etc. All true, but as used here in a combined unit, which means "power density" it still would make sense IMO. It's not like the "59" tells you that it's a strong motor and hence you want kW to compare it to other motors. You can't, it's just a ratio (power to weigth). W/g just reads much nicer in my head. Or we could come up with a name, like for other units. Let's call it "fainpul" (short fp) for example :)

59 fp is a new record for electric motors!

Much better you should post it and somebody mark the banner ridden one for deletion.

A much better link .. and probably not to late to change it via [edit] on submission in your view..

The YASA link is primary, links to test data and back story, and has more detail substance and authority.
