Starting this fall, the governAment's miles-per-gallon estiAmates for 2008 cars will be based on a more realistic method. The bad news is that the numbers will almost cerAtainly be lower.
The U.S. Environmental Protection Agency made the change because the old methAod, developed in the 1970s, didn't reflect modern driving conditions or cars. Many vehiAcles today spend more than half their time in stop-and-go traffic, where fuel economy is worst. Speed limits have risen-from 55 mph on highAways nationwide in the mid-1970s to as high as 80 mph today-and fuel economy can drop 25 percent when vehicles go faster. (A 4-cylinder 2005 Toyota Camry we tested got 10 fewer miles per gallon at 75 than at 55.) Air conditioning, which can reduce fuel mileage by about 1 mpg at 65 mph, is also much more common.

The new mpg tests will inAclude use of air conditioning as well as aggressive driving. And because fuel efficiency can drop with the temperature, some tests will be performed in cold temperatures.
The EPA's change in calculation is long overdue. In a study conducted in 2005, ConAsumer Reports compared the agency's estimates with ...
