Quote from Tweaker :

200 KM/H, not mph

And it says it takes 4.1 secs from 200 KM/H to 0 for the F1 BMW.

If a car stopped from 200+MPH in under 3 seconds, my god, would you have enough blood in your head?

Yes, it is KPH, but...

"when performing a full stop from 200 km/h, a standard-production BMW takes 4.1 seconds and covers 118 metres before coming to a standstill"

The road car does it in 4.1.

"Fifty-five metres is the braking distance a Formula 1 car travels when performing a full stop from a speed of 200 km/h. The process takes 1.9 seconds and creates deceleration forces of up to 5 G"
