From what I've read, it gets 27 miles of all-electric range and 83 MPGe combined. Tax incentives could at least partially offset costs.
The touring implications of a combined 83 MPG are profound; five extra gallons of gas adds 400 extra miles of range. The platform adds torque, slashes operating costs, and cuts greenhouses gas pollution. Win, win, win, win.
For these same reasons, and as Land Rover sits on the sidelines, I expect that Jeep's 4xe will do very well--especially among those who use their Jeeps for remote touring.
