2010 RX450 Premium 95000mls
My average is about 31mpg on local journeys but on a run I have had as much as 36/37 mpg.
However please be prepared for a drop to 27/28 mpg in winter.
Bear in mind that the size of the vehicle, weight and the V6 engine but this is still better than you would get with other V6 SUVs.
