Was curious so I asked the wife to start it up to take a look. Avg MPG looks in line with window sticker.

And even with me driving more conservative, the fuel economy is no different
Interesting that driving behavior makes no difference in MPG.

The window sticker on the Wife's 2010 reads: "Expected range for most drivers 15 - 21 MPG" (City MPG). Your measured city MPG looks to be in range albeit on the low end. Meanwhile... your measured 30 MPG highway is on the high end of window sticker expected range of 21-29 MPG. Perhaps one of these RX gurus can explain such a wide deviation in performance other than driving behavior/conditions.

In the meantime... what is your combined average MPG? Approximate amount of city vs hwy driving you actually do?

Are these figures for FWD or AWD?

FWD.

I believe the 2010 AWD MPG estimates on the window sticker are the same 18 MPG city, but 24 MPG hwy (1 MPG less than FWD).

On my RX350 AWD I currently have a fuel consumption of about 19.5 MPG, which is a mix of city and highway driving.
