We settled on the X5 50e. ~40-45 mile electric range with an overall ~450-500 mile range, and rather good performance when you want/need it. Total price well equipped was ~$92-94k. Also drives a lot nicer than the iX did.
We are getting an equivalent of about ~800 miles a tank. Could do better, but we only use the basic charger on 110v, which charges at a rate of ~1 mile an hour.
