22 mpg?
We've had a few questions about our fuel economy...as in, "why is it so bad?" For those of you who haven't noticed, we're crammed into a little car with 115 horsepower that most people think gets amazing gas mileage, but doesn't. Normally it's just shy of 30 mpg (which isn't really that great), but we've been averaging around 22 mpg and somewhere (it felt more like nowhere) in South Dakota, we bottomed out at 19! This is not good. Here's what we think is going on:
VW GOLF 2.0 E.P.A. HIGHWAY FUEL RATING (31 mpg.)
+
EXCESS WEIGHT (400 lbs.)
+
SURFBOARD (coolness factor of 7.3...7.4 dragohertz of drag)
+
BOX ON THE ROOF (dragacious coefficient of .83 millibars per mile)
+
EXTRA-LEGAL SPEED (mean cruise setting of 84 mph)
=
HUMMER-LIKE FUEL EFFICIENCY

So that's our theory. It's scientific fact.

Good theory. Keep in mind that resistance from the air (wind resistance) increases as the square of the speed...provided a constant coeficient of friction. So if you throw more more stuff on top of Rolf causing him to have to push more air the faster you go the worse the mileage gets...for better mileage decrease coefficient of friction (take stuff off of Rolf's roof) and/or slow down.

I taught him all he knows...
Where have you guys been? I suspect a ski break in Aspen? Hope you had a good Turkey day. Keep on Bloggin'.
