I know this is not about the topic so this will be my last reply, but Paul Tracey will never be asked to race F1. He may be picked up by a car manufacturer to crash test vehicles though. This is truely where his talent is.
I doubt the new RB will have herds more power than it's predecessor. The word RB seems to be usin to desribe it is 'efficient' so i don't think it will be braking any power barriers. I don't think it might have a little more bottom end than the X12 though.
