gallons per hundred miles make much more sense than that. incidentally, this is the measure rest of the world is advertising, except usually in liters per 100k

gallons per hundred miles make much more sense than that. incidentally, this is the measure rest of the world is advertising, except usually in liters per 100km. there's a good reason for this: comparisons linear instead of inversely proportional. 6l/100km is 50% better than 9l/100km. 30mpg vs 20mpg is... not as simple.
