OK, I have a question I may need help with.... 1) when would a person ever need the HV vs HV charge? I understand the sport mode and i totally get it. Why would someone choose the HV mode or HV recharge? If you run out of charge on a trip would you just bite the bullet and use gas? Why have the engine charge the battery???...is this an efficiency thing? Also, seems to me like the engine kicks in when I am driving with battery full, maybe it is just the generator and not engine. This car may be smarter than its owner!? I was kind-of expecting a 100% NO GASOLINE 45 mile ride before I started burning dinosaurs!.....lol... Can someone help me make sense of this? FYI....For the record....I am still in shock of how nice this car is for the price 36.5k with 7500 rebate, have i died an gone to heaven???? No lie,,,,I have owned 2 Lexuses and an infiniti..(top of the line) and I must say this vehicle has a good if not better a ride and interior than all 3 of those supposedly "luxury" super stars.....IM IN LOVE!
