you can talk about it all you want but it aint gonna happen.
Because.... You are on the Nissan's electric car division executive board and you single-handedly vetoed possibility of range extenders???
interesting that we take the entire weight of the battery pack against just the weight of the engine as if we could drop one in without any other changes?
No we don't. We leave the existing 24kwh 615lb pack in as it is right now and we compare an additional 615lb pack (provided existing technology and energy density remains constant) to get the Leaf to 150miles electric range to an additional weight of the range extender's full assembly that weights in at ~259lb, not just the engine. The thread is about economics of long range, so lets take everything into consideration, including the extra weight to carry for shorter daily commutes, extra price to pay initially and a necessity in another full ICE car to be owned and maintained. Talk economics - let's do it. As someone mentioned before, paradoxically, one would drive MORE electric miles if they had a range extender because they would take their REx car on a longer drive which would partially be covered by electric power vs. the alternative of taking the ICE car out of the garage and driving on gas for the entire length of the longer trip.
I'm all in for not burning another drop of gas if possible but today's reality, pricing and battery technology dictates to consider REx as a viable option economically speaking. When the technology/pricing of battery changes, it may and likely will become an obsolete approach but in today's reality dismissing it all together and completely throwing it out of the discussion is short sighted IMHO.
