The message I replied to was about performance, not range. PHEVs do not have 300 miles electric range, even BMW. I have an 45e and have no problems with it: it fully charges in ~7 hours, I drove about 6K miles last year and filled total 5 times (not full tanks, I live in an apartment building with shared chargers that go out of order for weeks so I fill up when charger is broken and I have less than 1/4 tank), it still has 90% of tank filled in the early November.
