So you are only having to fill-up once a week despite the 80 mile round trip commute?
drwrx wrote:DAMN! I am shocked. I figured you would get some impressive mileage out of that mill, but 54 mpg is just amazing. That is putting-up serious Prius like numbers.
I guess I have to ask, How is Miss Daisy? I have to assume to get that kind of millage you are driving her.

I'm sure you can find ways of improve aerodynamic efficiency; tape, louvers, perhaps a front splitter?
What is the Focus' coefficient of drag?
I'm sure with just a few hundred hours and a couple thousand of dollars I'm sure you can make the hypermiler even more slippery. Maybe even add another 1 even 2 mpg to the average!
Sabre wrote:VERY interesting on the mileage differences you are seeing. In other ways, it makes sense too: The colder charge is more dense entering the engine, which requires more fuel to keep at the stoic point. That doesn't change gearing though, so at the same speed you are using more fuel to make up for the denser charge.

Will be interesting to see how the Volt does.
Keep us posted.
