TBM uses 45 ~ 70 GPH per hour, depending on the performance profiles... 280K ~ 320K;
Call that what?
300 knots on 60 gph?
Around 5 mpg
Not significantly much more fuel than a 337!
Its not GPH but MPG that counts.
Oh yes, and overhaul, maintenance and insurance.
A C172 only uses 10 gph to go what, 105 knots?
So maybe 10 mpg.

I have a friend who prattles on about Mooney fuel efficiency.
I have told him, "It is not polite to discuss fuel efficiency in the presence of twin owners..."
