For me the PHEV is the ideal option. At least in Toyota's portfolio the performance is better, mpg is usually better, and MSRP is pretty reasonable if they ever actually build them. The number of trips per year that I would also take my crossover over 50 miles per day are relatively rare. And the PHEV would cover those uses. One of the challenges for most longer range PHEV owners I know is making sure to burn through a full tank of gas every 3 months or so to make sure it doesn't go bad in the tank.
I think the regular hybrid is a bit of a miss for towing. Not enough battery to flatten the mountains but almost all the weight. A 20kwh battery hybrid can flatten every pass in the USA highway system - probably a PHEV at that point. Full electric assist up the pass and the ability to regen the entire downhill run. It's just a matter of time for someone to finally develop them and produce in volume. I think the regular hybrid for a truck without a big enough battery for the mountains is pretty useless. And I'd also say EV trucks are pretty useless unless you're a fleet truck as a local contractor. For that - EV trucks are ideal. But for me - I would rather have no hybrid or a PHEV for a truck or SUV.
I do drive the RX on road trips, but most often drive the truck. With kids - midsize SUVs don't have enough room many times. Currently - living in Alaska - I'm probably 70-80% of the time pulling either a UTV or travel trailer for trips more than 50 miles away. But this isn't really normal situation where practically everything is 100+ miles away and I can drive for 20 hours and still be in the same state. Ugh. I need an airplane. If I were going to live here long term, no question - I'd buy one.
Yeah, maybe it's the specific vehicles I was looking at, but if a PHEV gets similar or better gas mileage than it's pure ICE counterpart along with the ability to run trips locally via electric, I'm all for it. Unfortunately the BMW X5 50e is not one of those. The RAV4 prime was always a pretty neat option in my opinion, but even there the 32 mile EPA range is mediocre at best. Something like the Prius prime with 44 miles or the BMW X5 50e (which I think is rated for 40) make a better case for them, but unless your commute is less than about 15 miles each way, there is a good chance you are not going to be able to do it on pure electric power (plus often driving those vehicles in electric only mode is super anemic).
I can get power here in Arizona now for 6 hours of the day at 4.3 cents a kilowatt hour. My "off peak" rate varies from 9.8 to 11.8 cents a kilowatt otherwise if I cannot charge purely in that 9 AM to 3 PM window (pilot plan due to the oversupply experienced by solar generation in Arizona during the day time with lack of ability to store it in batteries). With our gas lately being between about third and eighth most expensive in the US, electric is very tempting.
I completely get you about longer distance trips though. Arizona is funny since if you stay in the Phoenix metro you rarely drive more than maybe 60 to 90 miles in a day. Once you are traveling city to city in the west though, the distances get big really quickly. I think my issue is if I'm going to get a big comfortable vehicle like an X5, I want it to get the best possible gas mileage possible for distance driving when we are not just local. I'd rather have a pure EV run about to complement my "distance car."
Obviously, many of us cannot own a 3 or 4 deep fleet for personal travel though
