Well, according to Fuelly, my last few fill-ups in the Mazda have been in the low 11L/100kms. That's with mostly sub -20C temps, and mostly short trips - commutes to work 2.5kms away, etc.
That compares favorably to the beater Civic, which this time last year, was seeing mid 14L/100kms in similar conditions.
It compares especially favorably to the Tundra, which would be getting close to 25-28L/100kms at this time of year, doing short trips in cold weather.
I'm looking forward to taking this car on our road trip to BC, and really seeing what it can do on the highway. I've taken the roof rack off it for the winter, and won't replace it until we get back from our trip, so I'll get a true figure of what the car is capable of. I'm expecting (hoping) for mid-sixes.
