    Default Did The Ford GT-40 MK IV Really Go 220 mph at Le Mans

    Hey Guys,

    Trying to do a little research here and i'm looking for proof that the Ford GT-40 MK IV went 220 mph at Le Mans. So far i've uncovered this page of information:

    http://www.mulsannescorner.com/maxspeed.htm

    Which says that the maximum speed any Ford got up to was 212.6 mph at Le Mans in 1967.

    Could anyone contribute some more information to this?

    I know the owner of original Mk-IV GT40 J-6 through the GT40s.com forum and having met him at a couple of events. He is an extremely knowledgeable owner and has done lots of research on his car, which finished 4th at 1967 Le Mans. I will give him a shout and see what he thinks about the 220 mph claim and let you know what I find out. I have a recollection that Leo Levine, in his massive Ford history "Ford: The Dust and the Glory," said that the big Mk IVs got all the way up to 232 on the Mulsanne in 1967. Even though the Mk IVs had 16" rims and a very tall final drive ratio in their 4-speed transaxle, 232 mph seems out of reach. Even 220 seems a bit high, but I will see what an actual owner of a Mk IV who has put over 20,000 road miles on his car says and report back. I can also do a simple calculation using tire diameter, final drive ratio, etc., and see if 220 mph was mechanically possible.
