I would mention that the Santa Fe will probably not offer 150K mi warranty on the traction battery, and its electric range is probably going to be a lot less than that of the RAV4 Prime. Also, based on my personal experience and other sources in my environment, I believe Uncle Hyundai implements planned obsolescence with more gusto than Mother Toyota.
However, the Santa Fe will probably have a flashier tech.
If you are torn between a PHEV and an EV, this probably means that an EV will not fulfill 100% of your driving needs. I know I want a BEV, but there isn't one [yet] that can be my only car.
The Hyundai & Kia PHEV’s offer 8-year unlimited mileage battery warranties IIRC. I would hope to be replacing it before then with a BEV, as soon as 5 years when it will be a whole new world as far as automotive propulsion goes. It’s all-electric range is indeed less, 30 compared to 42 for the Prime.
Also note that it isn’t a traction battery. It connects the electric motor directly to a six speed automatic transmission that drives all 4 wheels. It’s a relatively standard, well-rated AWD, with a tunnel and all. That is one of the attractions of this vehicle. (I hate CVT’s.). The Prime’s traction motor is relatively wimpy, putting out 50 (?) hp IIRC. I prefer a more robust system to handle Colorado’s snow
The Korean brands have greatly improved initial quality recently. We’ll see if that extends to long term reliability. Their 10-year drive train warranties certainly would incentivize them.
Flashier, more capable tech is certainly an incentive for me, which is why I want to upgrade from the CX-5. I wish I could afford a Genesis GV-70e, that has even better tech! (Likely $70k lol.). Not ready to take longer road trips in any current BEV. PHEV is a nice compromise as most of our local trips are 25 miles or less.
