No instrumentation--didn't even know it existed (outside of Priusii -pl?) until today. Now it's on my wish list. We've mostly tried to improve mpg by decreasing miles driven.
Doing the math, as suggested above but with my averages, I get
short: 11.5 miles at 27mpg city = .43 gal
long: 19 miles at 36mpg highway = .52 gal
so it does look like shorter is better. But I'm still wondering at the equal driving time aspect and wondering if that needs to be accounted for. What rate of travel does city mpg assume, I wonder?
Thanks for everyones thoughts. And yes, we think the Matrix is a great car, though I don't like the styling of the newest model.
