Our Fuel Consumption seems to be affected by the prevailing temperature....when temp is in single figures we

average around 22mpg...when in double figs...around 32 mpg.

Is this common to other vehicles,or relevant only to ours.

Any comments would be appreciated

I have owned an RX400h SE since October last year.

My one criticism is the petrol consumption is nowhere near Lexus quoted figure, I get around 31mpg on my journey to and from work and around 28mpg on a motorway journey.

This is still very good for a vehicle of its type, but I do wonder why they don't make a diesel hybrid, surely this would be the true fuel saver.
