Electric Vehicle Innovation – Large All Light Weight Motor?

I was thinking. Who is the best runner. A man with strong legs or a man with long thinner legs? The answer might be the third option. A man with strong legs but oddly very light weight.

So the idea is to see if a strong large motor could be made very light weight. Not only the moving parts but all the parts. Since all parts of the motor experience vibration and acceleration in the vehicle direction.
