I'm not trying to contradict your overall good discussion, but obviously for the plug-in hybrids (PHEVs) 100 MPG is just the road gasoline mileage. If you only plug it in (no gas fillups) and only take short trips < 20 miles every day, it could be infinite MPGs...but that's not quite meaningful.
There are multiple "serious" considerations in purchasing a HEV/PHEV/BEV (not considering things like "need for speed" or a "sexy car").
- Cost of the car
- Energy and fuel cost
- Environmental impact - which mainly includes the CO2 emissions for powering the car and then the life cycle sustainability of making the car and recycling it at end of life (batteries, metals etc)
- And of course, whether the batteries and critical/rare materials are Chinese or not...!
In the USA at the present time, the regular hybrid (HEV) seems the best overall choice for most people wanting to change from a conventional gas vehicle.
- It is now nearly the same cost as the gasoline car (<$1000 difference). The PHEV and pure battery EV (BEV) are considerably more expensive.
- With electricity and gasoline both being cheap, the lower cost of running on more grid electricity (PHEV) versus more gasoline (HEV) isn't much of a saving for most drivers.
- In terms of CO2 emissions, with the current US electricity grid mix (gas+coal+nuclear+renewables), here is the comparison:https://afdc.energy.gov/vehicles/electric_emissions.html
The big saving in emissions is in transitioning from a gasoline to a HEV...beyond that, its not a whole lot more effective in terms of greenhouse emissions.
- Life cycle issues: the HEV has a moderately sized battery that lasts a long time and uses the least amount of lithium and metals. PHEVs and BEVs use 2-8X the amounts of these materials and currently have questionable environmental benefit outside of CO2 emissions.
