The Most Fuel-efficient Mustang Ever? A 50+ mpg combined turbo diesel Mustang?

It is obvious there are a lot of Mustang fans based on the COMMENTS under "WHAT WE"RE DOING".

It occurred to me that many Mustang fans are perfomance oriented.

My question is whether there is a significantnumber of Mustang enthausists that wanted FUEL FRUGALITY more than acceleration ...

How about an ABOVE 50 mpg(US) combined small displacement turbo diesel for those wanting 50 mpg combined or more ...

How about a vote "FOR" or "AGAINST" a fuel frugal diesel MUSTANG?

It will be interesting to see the results!
