@goro: Wake up boy!
1st read the information, we are talking about the 2012 SSS, this car declares 134 bhp, I haven't seen a dyno so I don't know if there aren't more horses there.
SSS: 134bhp/1045kg = 0,13 bhp/kg
Cooper S: 184bhp/1215kg = 0,15 bhp/kg
Doesn't it look possible to you yet?
My car has now 13000 kms, and keeps doing the same times, I timed it last week on 6,78 s, let's say my margin of error is 1 second (and that's waaaay to much!!!), then my car is doing 0-100 in 7,7 seconds.
You can cover the sun with one finger, but it's still there.
