I love Lexus vehicles and when I heard they were building an SUV I put money down to get one of the first. I love it but only have 1000 miles on it so far. At this point my mileage avg. approx 22 mpg in the city and hwy. I have done a combination of driving. It has gotten better as I have driven it. But I haven't seen it reach the 30 mpg yet. Other than that, I still have all the luxury and power I need. It gets better mileage than the '05 GS 430 I was driving that got 16 mpg, plus I have more space. I do love dealing with Lexus, they make it very easy to do business with them. So far, my family has purchased 9 different Lexuses.
The mileage read out and the read out that shows where the power is coming from, the battery or the engine.
