Hi,

The EPA is using a somewhat antiquated method of determining Fuel Mileage Estimates which was defined some 25 years ago and not truly representative of today's cars or driving style. These tests were conducted in ideal laboratory, as opposed to real world, conditions.

So much so, that the EPA has changed their testing methods and will apply these to 2008 model year cars. These new FMEs will show about a 30% reduction accross the board of existing FMEs, once more real world conditions are used to produce the estimates. Some cars, especially many of the Hybrid vehicles now on the market will see about a 50% reduction in FMEs.

I guess my point is that the current EPA Fuel Mileage Estimates are flawed and not an especially good Benchmark with which to judge your car's range and fuel ecomony...

Happy Motoring!... Jim'99
