Hybrid cars are touted as a "green" alternative; however, the financial aspects of hybrid ownership are not as clear. Consider the $2020$ Edsel $550$h$,$ which had a list price of $$5,400($including tax consequences$)$ more than the comparable gasoline$-$only Edsel $550.$ Additionally, the annual ownership costs $($other than fuel$)$ for the hybrid were expected to be $$460$ more than the traditional sedan. The EPA mileage estimate was $25$ mpg for the hybrid and $17$ mpg for the traditional sedan.
