Using the math contained in this paragraph:
"The price is almost twice the $21,700 that someone would pay for the absolute rock-bottom cheapest conventional Fusion, but Ford says the gasoline savings will add up. It says the plug-in could save $6,850 in gas costs over a typical five years of driving."
Lets pretend that the hybrid in question costs $40,000 for a difference of $18,300. That would mean that based on these figures you would have to drive the car for 13.3 years before the hybrid feature would pay for itself in savings and that is if the maintenance is the same over the same amount of time (new battery?). Of course your actual mileage may vary greatly depending on how you drive and gas prices going up greatly would shorten the time to payoff. I think most people would not see a return on their investment for the hybrid.
