> Toyota is going to be the monopoly automaker in every underdeveloped country and will be laughing all the way to the bank

You are probably aware that ICE vehicles can run on LPG or hydrogen and even diesel cars can run on synthetic dimethyl ether (DME). A PHEV with a 10 kWh battery or an EV with a small backup combustion generator make total sense as one can charge at home with a wall charger. Use the car regularily for urban trips of less than 50 km and run on some sort of fuel when one needs extended range for extraurban trips. Renault did exactly this with the new Captur PHEV. In markets where suffcient H2 infrastructure becomes available, automakers could sell a variant with a H2 tuned engine and fuel tank, in other markets they could continue to sell the gas version or gas/LPG. Of course, if one wants people to use LPG rather then gas, the gas tank can be made smaller as it's only required at power startup. Others automakers targeting first world countries with sufficient H2 infrastructure will use fuel cells combined with a smaller battery to accomplish the same thing and fully ditch the ICE.

I too think Toyoda-san has the right market approach. They also have a headstart in H2 tech.

Hydrogen is a totally different beast than LPG or NG, needing much different fuel lines and engines.

Toyota has demonstrated this on the Corolla H2 Concept. Their CEO, Akio Toyoda also raced this car to emphasize safety. The engine is not fundamentally different from e regular ICE engine, probably other seals, fuel lines and injectors. A quote from the press release[1]:

The car utilizes the turbocharged inline-3-cylinder engine from the GR Yaris, but with a few alterations to accommodate the hydrogen fuel.

Because the hydrogen is delivered in pressurized gas form, the same kind used in its Mirai FCEVs, Toyota teamed with Denso to develop special fuel injectors that could safely and efficiently introduce the hydrogen—which has a higher ignition temperature than gasoline and eight times the combustion speed—into the combustion chambers.

“Controlling abnormal combustion is the key to hydrogen engines,” said Naoyuki Sakamoto, the Chief Engineer of the project. “The abnormal combustion has the potential to add stress to the engine hardware. Therefore, we developed high-heat parts as well as adjusted the ignition timing and fuel ratio for the Corolla Sport H2 Concept.”
