Yes, you're right - the 680FP has the IGSO engines. I spoke to one owner in the Commander club who owns one and he says they burn quite a lot. Almost 55gals full pelt. That's a lot for a twin. I'm sure one can get it down quite a bit with LOP operation and 55%, but still. The 685 is probably closer to 60gph, but then again you can stick 10 people in there. I do not need that size of aircraft as I mainly fly alone/lightly loaded.
Yeah, the Cessna twins I'm just a little weary with what they will "invent" next in the form of SID's etc. I don't trust Cessna management.
