I have RX450h SEL - one month old and currently getting 31.3mpg. Best I have acheived on any journey is 36mpg - but only for part of the journey.

I have today started process of complaint and asked dealer to explain/test car. I am asking for them to take me on a run - I will pay for the fuel and demonstrate getting even 36mpg+ on a motorway drive.

Fuel consumption was a big influence on my purchase decision and 27% below published figures is unacceptable and I believe illegal under trades decription act.

Would really like to collect data from all owners on what they actuall get!

Cheers

I have previously owned an RX400h for four years and was getting close to the combined economy figures regularly, namely 32 to 33 mpg against published figures of 34.9 mpg. Admittedly thus was only achieved by not pushing the car hard and mainly driving on country roads with some town driving and very little motorway driving.

I am now driving an RX450h, which has only 4500 miles on the clock, but I find it very difficult to match what I was getting from my RX400h, even though the 450h should return about 10 mpg better for combined driving. I am driving in the same manner on the same roads as I had been with my 400h, but I'm consistantly getting only 29 to 30 mpg.

I have been around long enough to realise that manufacturers published figures are always over optimistic, but I was consistently getting within a few percentage points of the RX400h combined figures,whereas I'm not getting better than two thirds of the published combined economy figures for the RX450h.

Are there any other RX450h owners out there who are getting anywhere close to the published economy figures, or are they close to complete fiction?
