OK, talking about mpg and a Range Rover is worthless at best. If you want mpg, get something different. Consequently I have paid no attention to the mpg on my 09 HSE but earlier in the week, I had to drive 1000 miles in one day on Interstate 10. I set the cruise at 75 and was shocked to find that I averaged 22.4 mpg. I did do the math to make sure the computer wasn't lying. My G55 got 15 mpg at best.
