I don't know for sure, because I've heard three versions. But the one I believe is this;<br />It wasn't any particular year. Mercury was first,and used the rating at prop as a sales pitch. Other manufacturers followed suit.

I don't know exactly, either, but I think it was about 1979 or 1980.<br /><br />Red Sky....<br />JB

I don't think Chrysler/Force ever changed their ratings...
