Plug-in hybrid experience
I for one think EV's will be a "significant part" of our motoring future. It may or may not be the predominate mode in most of our lifetimes, but I believe it's here to stay. I would love to hear from any of our members who have first hand experience with EV's, cars or motorcycles. Personally I have regular access to a Tesla Model 3. I say "access" because it belonged to my late father-in-law and we now use it to run errands and transport my mother-in-law. FIL also installed a Tesla solar roof and 3 Powerwall batteries. For the way we use the car, solar takes care of all the charging power needed. Granted, this isn't for everyone; and the total investment is substantial, but I embrace the concept and envision other "alternative energy" vehicles and power sources in the future.
In my family, we have owned 3 plug-in hybrids, but no full EVs. 2 Fords (C-Max and Fusion) and now a Chrysler Pacifica. That said, I lease these vehicles rather than buy them because the technology is forever shifting. Three years and it becomes someone else's problem.
The PHEV is good around home, where I can run most errands strictly on battery. Even so, I have no interest at all in car that is strictly EV like Tesla. At least with PHEV you have the gas engine to fall back on for longer trips or if the battery runs out sooner than expected.
There is no maintenance savings with a PHEV, because you still have to service the gas engine. On all 3 PHEVs, we have ended up getting oil changes done because of time (1 year, as per owner's manual) and not because of mileage. Although the electric drivetrain is warrantied for 100k miles, it will be hugely more expensive to replace the battery than to rebuild or even swap out the gas engine. The powertrain is also much more complex to accommodate the two drive systems, so I'd imagine overall the maintenance cost over the life of the vehicle will be higher than gas alone.
I do like the electric motor torque; it feels really strong starting off. Once you're up to speed, that advantage pretty much goes away. Start climbing hills and you'll be running on gas not battery very quickly. Another quirk is that the transmission in all three has been a CVT, and all have electric steering assist.
In a twist I didn't expect, running the heater runs down the battery much quicker than the AC. It appears to me the heater draws far more current, and from a colder battery as well. It does not get really cold where I live, with temps below 30 degrees a rare exception. It does get very hot, although that seems to have a lesser effect on battery capacity.
Hope that helps answer your question.
