Got 26.7 MPG in my GS430!!!
Just finished a 730 mile day 
in my 06 GS430. I was surprised that I got and average of 26.7 MPG on my last tank 
. All freeway driving at 70-75 MPH. Set my 18" Yokohama Run Flats on 33 PSI and had a very enjoyable ride. The new GS actually rode as well as my 98 GS on 16" wheels on some pretty rough roads.

Fuel economy seems mighty impressive for the V8.
