The US Department of Energy has issued its 2010 Fuel Economy Guide with updated mpg information. The Guide is also available for your mobile device at fueleconomy.gov/m.
The 2010 MINI Cooper with manual transmission (28 mpg city/37 mpg highway), the convertible MINI Cooper with automatic transmission (25 mpg city/33 mpg highway) and the MINI Cooper with automatic transmission (25 mpg city/33 mpg highway) are listed as the 2010 Minicompact Car Fuel Economy Leaders. The S, JCW and Clubman had similar numbers but did not finish in the top three because they cost more.
