As a consumer, this is absurd. I am not so wealthy that I can simply go out and install chargers anywhere that I may need them. If I had that kind of money, I'd just buy a Tesla. No, if I want to dramatically decrease my footprint today, my best bet is a PHEV or BEVx. That's exactly why I have a PHEV to compliment my BEV.

In the long term, you are correct. This is the solution for an EV future. But I'm not going to sit idly by and wait for this to happen - I've already changed my "fleet" to work with what is available today.

I am pretty sure that @edatoakrun implied in a couple of other posts that the fuel would be directly combusted for cabin heat. That is why he favors propane as the fuel, as it can be combusted in the cabin without elaborate exhaust consideration, and when the vehicle is stationary. But I am pretty sure that he is aware of engine heating. I brought that up because it was not obvious and his fine post may give the misimpression that furnace heating is required in a SEV. It is not.

Yes, I stated that, in my first post.

="Interleaf"...That is why he favors propane as the fuel, as it can be combusted in the cabin without elaborate exhaust consideration, and when the vehicle is stationary...

Perhaps greater advantages are:

Propane infrastructure is already quite mature and ubiquitous in the USA, needing only to be slightly adapted (longer hours, self-service?) for even more convenient use by to BEVx drivers

Propane is not a GHG, is harmless to human (and other) life in low concentrations, and has relatively benign combustion emissions.

Propane is stable. A canister can last for decades without leaking, degrading, or gumming up your ICE (like gasoline does) when you finally decide use it.

="Interleaf" ....I am pretty sure that he is aware of engine heating...

I am, but consider the added complexity and limited benefits from using liquid coolant/heatent to capture the waste heat from a 5 to 10 kW ICE, heat which would only be available on extended trips, and then only useful during very cold weather.

IMO, an efficient heat pump (which could easily be set up accept waste heat from an air-cooled ICE, when occasionally available) with combustion-back-up for occasional long trips at very low ambient temperatures, would probably be more practical.

Direct Propane heating creates a lot of water vapor, a means of dehumidifying the air would be necessary

Which, along with all other combustion products, should always be vented outside the vehicle.

Near-confirmation of the long- rumored Mazda "electric...equipped with a charge-supplementing generator" vehicle.

It remains to be seen whether Mazda will somehow manage to do what BMW failed to (IMO) accommodate CARB regulations and still produce a functional “range–extended” EV.

Though I don't see how that is possible, unless Mazda can change the current idiocy of CARBs BEVx requirements, battery depletion prior to generator operation and a tiny fuel tank, or it just classifies its BEVx as a PHEV in California for compliance purposes.

Mazda’s Rotary Engine Returns for 2019 — Just Not How You Had Hoped

...Mitsuo Hitomi, Mazda’s global powertrain head, gave us a timeline to sink our teeth into. The year of the Wankel will be 2019, but it’s not coming back how you imagined. Instead of dropping it into a high-revving performance vehicle, Mazda thinks a rotary would make the perfect gas-powered range extender for its upcoming electric vehicle.

“I think that’s probably what it will be,” Hitomi told Automotive News during a sneak preview at the Japanese carmaker’s Japanese proving grounds.

According to Hitomi, Mazda Motor Corp. feels that the rotary’s ability to make gobs of power in a small, low-vibration, package would make it an ideal range extender on its first battery-powered car. But it also serves as a nod to the company’s heritage and keeps rotary R&D alive.

Akira Kyomen, program manager for vehicle development said the new EV would come in two flavors — purely electric or equipped with a charge-supplementing generator. Mazda’s plan is to market the basic EV in Europe, Japan, and China but acknowledged that North Americans clock more daily miles on average and would appreciate something to alleviate range anxiety.

Mazda says its new EV architecture, set to arrive in 2019, will accommodate BEVs with or without range extenders — as well as hybridized powertrains...
