I think that you would get the exact same figure for fuel consumpion as the EPA dyno figures, if, and this is a big if, you could duplicate the conditions. Trouble is, you can't.
You could drive on perfectly flat ground (like the EPA test), and follow the cycle they prescribe (which is fairly sedate), and eliminate wind resistance somehow, and have the air conditioner off, and always have a cold engine in city driving, but those aren't real world conditions. The EPA test is designed for comparison with other vehicles under the same controlled conditions, not as a predictor of actual mileage.
