Do you keep your engines on recharge mode for this? I have done that before in my VIIB to increase range but seeing as you lose speed while "recharging" and you are theoritically still doing the same RPM i.e. same fuel burn i thought the benfits might not be all that great. I haven't done the maths on it, i might do it now in my IXC actually.

The RPM is the same, but charging the batteries puts more load on the diesels so you need more throttle to maintain the same speed. More throttle = more fuel burn.
There is efficiency loss in charging the batteries and in transferring the battery power to the E-Motors. These efficiency losses are not present when running direct from the diesels. This means that
running electric motors uses more fuel.
