These performance figures appear to be in dispute, I have a figure of 6.1 seconds for 0-60 but 6.5 seconds for 0-62. Clearly it can't take another half a second to go from 60 to 62, so if anybody can shed any light I would be most grateful, I have also seen a figure of 5.9 seconds for the 0-60 time, again if anybody can clarify it would be helpful.
