Ford Fusion Energi. When you receive it will have around 25 miles of all-electric mode so no gas will be used. After that it kicks into Hybrid mode at 45mpg. My overall for life of car is almost 80mpg!
Car has a larger backseat than the Volt, so passengers sit comfortably. Small trunk though, since that's where the large battery pack is. Overall a great car for long-term trips.
