Thanks for posting. I've been seriously considering a BME PHEV and 2 things come to mind..........
1) This is a heavy car without the massive battery and got heavier for the 2020 model year. BMW needs to put the PHEV on a diet.
2) That Monroney with the annual fuel cost is calculated at $3.25 per gallon. I'm guessing that the total amount is quite a bit lower due to the oil surplus.
Below is a random X3 sDrive30i Monroney. The annual fuel difference between the two can be seen.
