Speed ratings are very complicated. I drove a Ferrari 599 at 205 mph, a McLaren SLR at 204 mph, and an Audi R8 V10 at 195 mph. In each case, the vehicles were above 186 mph (the tire speed rating "Y") for no more than 15 seconds - I just watched the video and timed it. The venue was a long airport runway. The P Zero tires were brand new (that morning), and the ambient temps were cold. Heat is the big enemy at that speed, not centrifugal force, so I was hardly worried.*

The story runs on Autoblog this Friday.

* I was worried I was going to die... but more exited about going 200 mph than anything else.
I am fortunate to have unique press cars delivered weekly, but I own:
'13 Audi Q5 2.0T Quattro 8AT
'86 Porsche 911 Turbo 4MT
Gone, but never forgotten... my E70 X5 35d, E90 335i, E46 330i, E36 328i, E70 X5 3.0si, E53 X5 3.0i.
