I know. Not what I was expecting to see. Projecting the slope, apparently at about 210 km/h the car would be getting 0 mpg.

In fact, I the day I did the original (green) plot, I was collecting one more data point @ 110 km/h, but I discarded it because one of the bi-directional runs was ruined (I think I caught up to another car and had to brake - speed limit is 80 on that road). But the one "good" data point was around 43.x mpg, which would have started to suggest a more expected plot, more like these:

Speaking of which, have you thought about tracking down a set of taller wheels/tires and running another one of these tests Darin?
To see if it gets better still than the taller final drive? I hadn't considered it (mostly because I don't know anyone with the same bolt pattern - 4 x 114 or something).

Anyway, what's the point of measuring speed in km/hr if you're giving your fuel economy in mi/ga?
Because I have to drive in Canada, but I mostly talk about fuel consumption with Americans.

Really, I'm tri-lingual: MPG (US) for the bulk of the conversations, L/100km for the enlightened Canucks, and MPG (Imperial) - still - for the majority of the unenlightened Canadians.
