I'm confident that it will go 200km/h - but you will run out of battery quite fast at those speeds (in much less than an hour), as it's obviously a lot less efficient.

Square power law applies to speed when air friction is factored in. It takes 2.37 times as much horsepower to go 200km/h versus 130km/h.

And then you have to cool everything, and generate more down force, which will take more energy.
