From the article:

The accuracy of the Environmental Protection Agency (EPA) fuel economy estimates on new car stickers has long been debated, usually with the anecdotal conclusion that they’re wildly optimistic. A change in methodology and testing standards in 2008 adjusted the numbers lower, taking into account higher usage of air conditioning and higher freeway speeds. Most vehicles had their figures adjusted lower. Based on the self-reported figures,diesel driversreported a fuel economy average 20 percent higher than the EPA estimate, according to an analysis of figures by AAA. The next-best category was vehicles equipped with a manual transmission, which achieved an average fuel economy 17 percent higher than EPA estimates.
