Interesting that you would just "happen" to show up now to make a totally uneducated, not to mention rude, comment. You don't know me or my driving habits. I am well aware of all the variables that effect gas mileage and have tested this vehicle from one range to the other extreme. It has underperformed in ALL cases. I bought this car because I had a very high opinion and experienced history with Lexus. I have rented the Highlander on multiple trips - IT outperforms the 450h hands down. Hopefully you will try to refrain from making assertions you know nothing about. Best

Paul, A small percentage of vehicles are actually tested by the EPA. The vehicle manufacturer actually supplies the EPA with the estimated mpg numbers! I strongly suspect this is the case with the 450h due to the huge variance in the estimated mpg's versus the customers actual experience.

I agree with Ben. The deciding factor in purchasing the 450h was the excellent mpg rating!!! I would never think that a person would have to search all over the internet to find out that the vehicle they want to purchase does NOT EVEN GET CLOSE to the estimated mpg it has advertised. Especially a brand that is not 'cheap' by any stretch of the imagination. I purchased a Lexus because I wanted a luxury high quality vehicle WITH good fuel economy. Buying the more expensive brand was weighted specifically by the savings granted with the fuel economy. Furthermore, I am appalled by the responses given by Paul. I have never had problems getting [very close] to the estimated mpg with every car I have owned. This car is pathetic. I have never gotten [even once] the estimated mpg on my 2010 RX 450h. If Lexus is aware that this car does not get that type of gas mileage, as it appears they are, then they should never ever put it on the stickers for the vehicles and in the specifications!!!
