From the NYT Science Times: M.P.G. Can Mislead When Searching for Fuel Efficiency
Excerpt:
"...the researchers say, the relationship between consumption and m.p.g. is curvilinear, and there is a greater savings at lower m.p.g.’s. Over 10,000 miles, the 28 m.p.g. car uses 198 fewer gallons than the 18 m.p.g., more than double the savings of the 50 m.p.g. car compared with the 34 m.p.g. one.
With this new measure, the researchers suggest, consumers would more easily see the value of swapping an inefficient car for one that is even just modestly more efficient."
