A fair bit of controversy about this at the moment. See video here

Apparently the video doesn't add up, the tyres are being pushed beyond limits and the gear ratio wouldn't allow the stated top speed (apparently top speed was achieved in 6th gear). There's also several other videos that show the maths doesn't add up.
It's going to be interesting to see how this unfolds.
