The Lightning ended early because the aluminum plant fires were cutting Ford's ability to produce enough F150s of any kind. They make more money on the ICE trucks than the EVs, so the Lightning got the axe first.

> EREV (pretty much PHEV)

There is not much relationship between an EREV and a PHEV. An EREV is way, way closer to a BEV than it is to a hybrid. And I'll eat my hat if Ford actually releases an F150 EREV. That announcement was to mollify angry customers who thought Ford should not have killed the most popular EV truck on the market.

Frankly I'll be surprised if anyone seriously goes for EREVs. They make very little sense, which is why (AFAIK) it's only seen production once or twice in small numbers.

EREV vs PHEV, in the US, is separated by "do you get more range on battery or gas". That's why US version of i3 got electornically limited gas tank to qualify to be called EREV.
