"So Alonso overtaking Schumacher like he was in a milk float had nothing to do with power output? I beg to differ, ok I don't have the straight line speeds of both cars cos that's not on the data from the f1 site, (that system is so cool when it works)." LHatkins So you rip off the comments from ITV about how ALO overtook MSC and then post them on this forum. Did you not understand them when you pasted them in here? There is a very strong hint in there as to what happened and why ALO was able to overtake MSC. And as I said before it has nothing to do with power. Ian
