Sold my Yaris. Bought a decidedly NON-economy car in Cincinnati, flew out and drove it home. Did a little half-tank hypermiling experiment along the way. (was going to do a full tank, but it's really hard to drive 5-10 mph under the speed limit on the interstate in a fast sports car, so I cut it short)

So, this was along I-65 from Glendale, KY to Falkville, AL. Speeds were mostly 60-65, sometimes up to 70, occasionally dipping into the 50's on coasts if there was no one behind me. (which was the case here and there toward the end) Hit some afternoon rush hour traffic in Nashville that knocked off a little MPG. The on-board display read 36.1 when I filled up, so it was just a little optimistic.

Car Type: 2006 BMW Z4 3.0si Coupe (manual)
Miles on Car: 53000
Gallons: 7.161
Miles: 252.6
MPG: 35.27
EPA: 28
% Improved: 25.98%

Pretty impressive for a sports car that will do 0-60 in under 6 seconds, eh? And it'll return 30-31 mpg in "normal" highway cruising at 75-80 mph.

Looks like I need to hit 39% to beat my best in the Yaris. That would be about 39 mpg. I know the car has more in it if I keep it under 60, keep my foot out of it on acceleration, and avoid traffic. It will surely to 36, and probably 37-38. Don't know if I can stretch it to 39. I'll have to make a back roads hypermiling trip one of these days and find out!

Hmmm... roads are usually pretty quiet on Thanksgiving day...
