I didn't see this video posted here. Turns out the 60 is probably just as quick as my non-performance 85. Enjoy!
I've suspected my 40 (60-, 40+?) is faster than the official 5.9 time. I don't have the equipment or the track to test it out. Do you know of other sources that back this up?
Your 40 has the exact same performance as the 60.
For another source, check out Motor Trend's car of the year review. If I'm not mistaken, they measured the P85 0-60 @ 4.0 and the non-performance @ 5.0.
