I've been driving mine for about 5 days now. I have about 500 km on the counter.
So far I'm doing about 12.4 liters per 100 km in city, about 19 mpg if you're still not like the rest of the world ;-) By the way, I would say I'm an aggressive driver style
On the highway, I'm doing about 9.3 liters per 100 km, about 25 mpg, on the cruise control, about 115 km/h (71 mph).
So far winter had still not arrived here. Temperature has been around 4 degree celsius, about 39 fahrenheit (please do something about that, ISO has to be accepted someday in America too, hehehe)
By the way, I would like to thank my sponsor, Google, for all the "Rest of the World" to "United States" free and fast conversions

hehehehe I hope that guys from Nasa are actually taking notes here instead of burning up another satellite in Mars atmosphere one day because of this ISO conversion thing
