I am re-posting this in the mechanical section.

It shows how the power is split up between the ICE and the main traction motor in CS Mode at 70 MPH when power split is engaged. It also shows the gear ratios and the equation for the Volt planetary gear set.

I'm pretty sure it's correct. I would feel more comfortable if WOT had put his blessing on it. He is quite the wiz when it comes to transmissions. He's the only person I know of besides BillR that understands GM's 2 mode. (He owns a 2 mode truck or Tahoe.)
