Yes. It's an UrS4. AND it is green under the white overpaint, i.e. GREEN is the fastest colour.

I take it the guy was doing 220mph on the public road seeing as the video has been removed?

That's fast! Must take a lot of power to do that.

Nice inboard sound!

The 100/C4 chassis is a good choice because of it's low dragcoefficient.
A GT4088 making 738hp @ the wheels is a bit optimistic though...

IIRC the car was dyno tested at altitude where they use correction factors, FWIW.
