I'm guessing you're talking about the Ford Fairmont Futura from the late 70's & early 80's. (I drove my Mom's '79 Futura when I was in high school)
Ford used the name "Futura" on several cars since the early 60's - dating back to the 62 Ford Falcon Futura. From what I understand, the name is still used on a car that Ford Australia sells down under today.
