I'm not saying the F90 isn't fast, because it's very fast and DCT / ZF8 operations aside, has anyone considered that 640whp on whatever tune and on whatever dyno that the F10 was tested on is not actually making 640whp? Dyno numbers can be so hit and miss as well as different tuners. But the video clearly shows the F90 accelerating well, while the F10 can't keep up. This is why vBox numbers are more reputable when it comes to testing power. By my judgment of the video, my opinion sways to the side of the equation where the F10 is not actually making its reported power output, it seems to be lower. Again, just my opinion based on the evidence shown.
