Edit : just saw above post. They don't really get 10 mpg do they? Surely with a light foot you can get substantially better mileage than that!? What's the mpg at a steady 70 mph highway?

Hell my old '96 Range Rover LWB got 15 mpg in town. My F250 460 X-cab 4x4 got 10-12 mpg - carrying a freaking camper.

Our 05 Turbo got around 14mpg around town, did far better on the highway. Our 2011 gets around 18mpg around down but is considerably more efficient on the highway. But, if you bury your foot into on the highway the difference is less.

Did two identical drives a couple of summers ago one week apart. Here to the interior of the Province over high mountain passes. First drive had wife with me and my two racing bicycles on the back of the truck. Never really got into the boost much, drove about 125kmh once in the mountains. Sipped fuel. Fast forward a week and it is just me that needs to get back up with my bikes for some racing. I leave late but still need to arrive on time for a group dinner. I get behind a Z06 vette and an M3 once we get in the hills. Figure they can find the radar for me. We average about 165kmh in the mountains. I'm in the boost a fair bit . I don't have the exact numbers but the first trip was 3:40. Second trip was around sub 3:05. But I burned approx an extra 1/3-2/5 of a tank....
