I recently read a German comparison test that broke down costs to Euro-cents per Kilometer for a selection of new cars, including all possible expenses (gas, insurance, tax, depreciation, etc) and based on an average annual mileage. The cheapest car was the base-model Smart with the smallest engine, and it came to EUR 0.27/km, which would be about 55 cents/mile. This amount would be a little less in the US as there are lower taxes and insurance costs.
