The powertrain, in my opinion, is one of the few bright spots about the HS, the 2.4-liter Atkinson-cycle powerplant delivers healthy 187 combined HP through the smooth CVT transmission. Although the hand-off between the gasoline engine and electric motor is noticeable but it is probably the best in the hybrid world up to date. Lexus claim 0 to 60 in 8.7 seconds and according to my butt-lerometer is about just right, which is not bad at all for a hybrid that returns 35 MPG combined.
During the week that I had the HS250h I have put over 1,400 miles on the car, the distribution is about 2/3 highway and 1/3 city. According to the trip computer I have achieved over 34 MPG (34.3 to be exact) over the entire week, almost identical to the EPA numbers:

Overall the HS is very impressive in the powertrain department, it is just a better suspension tuning away from being another Lexus masterpiece.

@ Todd,
I would wait until after the break-in period, if by then your mileage still did not improve then you should bring it back to the dealer. As for right now I wouldn’t worry about it.
