I have 2 concerns when looking at say a BMW X5 eDrive50 (or whatever name it has). 1) The fuel tank is 3.7 gallons smaller than their gasoline counterparts. Since these plugin-hybrids charge slowly, you're still suffering from having a hybrid while doing these long road-trips. 2) I often wonder how these engines are protected against wear when the engine is cold, but the battery runs out and they need to rev up from dead-cold.
