1. When the motor is assisting the ICE, it's pushing it down into a less efficient part of the BSFC map. You'll be getting considerably less power from the ICE, but it will only be using a little less fuel.

Not entirely accurate (look at the E-Wheel jobber), many vehicles during acceleration and at low speeds are HORRIBLE anywhere above idle. If said vehicle has a manual leave motor off and drive electric at low speeds and in the energy wasting reverse area, start to go faster, regen for braking at all speeds, automatic do the same if the vehicle is one of the few like my old sub that doesn't seem to care about being pulled 80mph 300miles in neutral or have gasser operate at the RPM that removes engine braking. Also many pickups with V6's or small V8's lug at highway speeds and AREN"T very powerfull meaning you have to push further than you should on even a small incline or in moderate wind. This config would offer an assist so these vehicles do not enter this inefficient area.

Remember the Accord Hybrid. Same V6 as the regular Accord (not to mention millions in R&D), just with motors added. Economy was worse than the 4cyl version.

Very true we would all like to see well engineered designs, sadly in these areas somebody has to make a lot of time and money wasting mistakes before we will see one that is usefull, just the way of things.
