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

There is no cylinder shut off in 2003 and latter v12, your 2004 does not have that function

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 am hitting 23 mpg without cruz control, I hate cruz control, but I think I will try it and see if it get even better numbers.

Formerly W215 CL600
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.
