The EREV concept is very very old, and worked fine in diesel/electric locomotives, submarines, etc.
The start of the modern era: Back around 2008, people were adding batteries to their Priuses, to make them into Plug-in Hybrids. Simple concept. Worked OK.
Back around that time, I designed and built a microcar PHEV of the series (i.e. EREV) type. Also back then, or just a little later, Fisker came out with their series hybrid, which performed pretty well, but the business did not. The Chevy Volt came out in 2011, and was quite reliable, needing a small fraction of the maintenance attention that the air-cooled VWs (decades earlier) required. (I worked on loads of them during my college days, and owned several. )
Eventually, Toyota would come out with the Prime PHEVs. Great cars. Super efficient when running on gas, but can also be run entirely on the battery for the commutes of 92-93% of the population. Plug in every night, and for many people, the engine would not start for weeks. (Most well-engineered PHEVs will automatically start the engine periodically to keep it limbered up.) The Primes, although fairly complex, are very reliable. (Stale gas? Never had that happen in my 7-8 years of Volt ownership. You quickly learn when to fill up and how much to put in. Brakes: never needed them. )
Jumping back to 2008, I built my EREV largely because it is a very simple form of hybridization, and because it allows the vehicle to operate on the battery alone when desired. My little car was designed to be a commuter, so with 40-mile electric range, it would solve the needs of 92% of all commuters. If you wanted to go across the state, then you'd start the engine whenever the battery got below 50%. (It would automatically cut off when the charge rate fell off, meaning the battery was nearly full. -- This "feature" was one of very few things that was automated.)
The battery pack could be small and light, as compared to the pack in a pure BEV. The engine and generator together weighted slightly less than the battery pack, meaning that I could have made the car a BEV with 80 mile range without the extender, but the cost would be higher, and 80 miles is not an impressive range... and this was long before public chargers.
The generator (the thing driven by the engine) and drive motor were identical. Starting the engine only required connecting the generator to the battery (via a contactor, a heavy remotely operated switch) and the generator would spin the engine to get it running. No starter motor required. (The Ram EREV does not have a starter motor either.)
I was considering marketing my little vehicle, and went so far as to make a second, modified engine with simulated Atkinson timing, higher compression, fuel injection, etc, to increase efficiency and reduce emissions. The generator and motor were both 91% efficient, not much lower than those of today.
Why do I mention all this? To say that the idea of an EREV is inherently simple. A guy without any serious funding can build one is his garage.
Ford and Ram will both be offering all sorts of luxury features and loads of things to break. Their engines will probably not be one of the things that breaks. The transmissions are far far simpler than those in a typical ICE vehicle. If you read through this forum, you will find many things that people complain about, despite Lightnings not having engines. There will be loads of different modes to tweak so that the vehicle fits your needs.
So fear not: 1. you already have your Lightning, (hang onto it 'til Ford comes to its senses) 2. if you want great range in a BEV, get a Sierra. 3. The Ford EREV truck and Ram might be worth taking a look at. 4. The new smaller platform is still on the way -- I hope.
This has been linked before, but it is worth looking at if you have not. The Ford will be very similar to the RAM.
