Recent 50 mile trip from the shop. Placed cruise at 60mph and got 25mpg! That cylinder shut-off technology is great.

Interesting, didn't know that. Either way, it's killer mileage for the bi-turbo V12.

If you can keep out of boost (which the cruise control does a good job at) the mileage is pretty decent. Accelerating around town under boost just kills the mileage.

I've done a couple of several hundred mile road road trips and the best I've gotten is around 72 mph I can push 22mpg that's it, anything slower the mpg decreases.
