This is a great achievement. I know Wayne was hoping for mid 60's with two aboard, so in effect they beat their own expectations - with three aboard. Hopefully Guinness will accept this as a record and there will not be any technicalities. I agree, it might be beaten in summer or in an Insight II, but I doubt it will be beaten by the 11% they managed over the previous record. Great point Kacey, if Honda is smart (and my impression is that they are and that they just love this engineering stuff) they'll be examining the logger, any ECU adaptive parameters, and the car very carefully.
