The last time I used a Ford product was the 289 in my Sunbeam Tiger (bought it new in 1965, and still have it). I've been watching BEVs and PHEVs for years, and wondering why the factory did not improve on the various Prius hackings that were available, and finally disappointed that the PIP did not have a bigger battery.
We decided that our lifestyle did not allow for a BEV; even though most of our driving is local, we do take occasional trips into areas that don't have charging stations. So we decided we needed a PHEV. I've also been watching battery technology, and although it can't be said to be following Moore's curve, I do believe we are going to see a significant improvement in $/energy density over a period time that will be shorter than the expected ownership interval for our car. So it was important to find a PHEV that was friendly to getting the battery replaced in a few years. This ruled out the Volt, as it's battery is so integrated into the frame that it would be a bear to change.
We almost bought a PIP, since the factory was offering a $4500 discount. But the Energi's ride, better all-battery range, and amenities like the big sunroof won out and we bought one on Jan. 2 this year. Despite the 40 mi. it first spent at the dealer's doing demos, we are up to a combined 75 MPG at 2,000 mi. The two times we have filled the gas tank since we bought the car will take us well into April.
Even though we use the L1 charger that came with the car at home, we have had two occasions to refill the battery using a charging station (L2), and in both cases the juice was gratis! We have joined ChargePoint and may sometimes actually pay for the juice in the future- still a great deal.
