I was looking at pictures of trucks the other day and I found these 4 concepts that Ford made over the years, and its pretty interesting to think back what kind of impact these concepts made.
-1994 "Ford Powerstroke" --debuted Ford's new 7.3l electronic controled diesel and the famous "Powerstroke" name
-1997 "Ford PowerForce" --essentially debuted the "Super Duty" bodystyle, which is now 10 years old and still being used.
-2002 "Ford Tonka" --debuted Ford's new 6.0l Powerstroke, and gave clues to the styling of the next generation Super Duty.
-2006 "Ford SuperChief" --provided insight into the New 2011 Ford Super Duty.
