Please offer a plug in hybrid version of the Lincoln MKZ. If anyone can afford the technology, luxury customers can, but perhaps less so the mass market. In addition, it would help if you could customize the battery size (and with the new Fusion Energi) similar to the way you can customize battery size with the Tesla Model S. This obviously mitigates the cost of the expensive technology, while still serving the customers needs and improving the environment. After all, if my commute is 10 miles, why do I need Chevy Volt sized battery most of the time? Obviously this creates some technology / software programming hurdles, but I would hope the smart guys at Ford could figure this out.
