I have heard of that, how does that work do you have to be using Nav at the time, or is there a "Bonus" button that you push that gives you a short period of EV. This would really benefit me because I have no problems if I run out of EV before arriving home, except for this one short, steep incline in my neighborhood which unfortunately is immediately after a stop sign at the bottom of the hill. The speed limit in my neighborhood is 20 mph and in EV it has no problem going up the incline from a standing stop. However with 0 range I can only crawl up at around 5 mph without the engine coming on really loud, apparently the system detects that I am climbing uphill because of the slow acceleration compared to the throttle position (sorry for the archaic term). It's a bit embarrassing making all of that noise in my otherwise quiet neighborhood, especially if I am coming home late at night. With some skill and practice I can usually build up enough regen prior to that so that I can go quietly up the incline at 10 mph which is a little better, but if I could somehow indicate to the system that I only need a very brief amount of EV that would really be terrific.
