Careful guys, the 2010 & 2011 are LIMITED to 155Mph (250Kph).
The 2008 & 2009 are limited to 186Mph (300Kph) not that they can get there.
Check out Freds comments on the data downloaded from the ECU.
So, I can confidently pronounce that 2008/2009 are indeed faster, regardless of what colour.
That said, Black is of course the most manly colour, but I do hanker after one of them green ones.
