Where did the extra 250 NM come from when they combine the ice and EV?  Math?

The whole thing is a math puzzle. Shows the extreme length they must now go to I order to compete with a simple little electric motor or three.  My head is spinning from the complications and busy shapes and switches everywhere.  Are we to the point where we laugh out loud when we see people in these or worse, buy this thing. 
How is the autopilot?
