Sorry I'm not going to answer all your PM's individually but they all seem to have the same common questions so I will try and answer them the best I can.
IHI is not a technical partner any longer and not supplying components for "free" but they are still manufacturing some TC components to Honda's specs.
I don't want to get into this whole Alonso thing. The only thing I do know is that he is not the reason for the McLaren - Honda divorce. If Humpty Dumpty were driving for McLaren instead of Alonso the break up was inevitable.
The new Spec PU really needs different gear ratios in the higher gears to fully exploit its power band. Although the new PU should definitely see a power increase, the big gain should be a more efficient relationship between the ICE and H unit to benefit harvesting and deployment.
