Prius 2004 MPG claims (Score 1)

I think that simply allowing Toyota to hide behind the EPA claims is a big mistake. On their website they do calculations for fuel savings for you assuming 55 MPG. I have 4 Toyota cars and all but the Prius live up to the advertised MPG claims. Why is the Prius an exception? My 2004 model thus far reaches only 44 MPG at moderate temp, no A/C, no hills, no cargo, city driving, and no passengers. My dealer states that it takes about 1500 miles before the car is finally up to efficient performance. Did anyone hear similar complaints?
