Sounds like a lesser option to the PHEV XC60s I’ve had, but maybe manufacturers could increase battery sizes in these configurations to be the primary power source rather than a boost to an ICE. Our XC60 was something like 315hp ICE w/ 140hp battery? Total was 455 ponies and 0-60 in 4.5. While we only got about 25 useable EV only miles, we filled it up maybe twice a year.
