Okay so I drive a manual transmission, which is different... But in-gear coasting is 999MPG (actually infinite), which is just engine resistance. Neutral coasting with the engine idling is somewhere around 200MPG at ~40MPH.
So neutral coasting in an automatic, even with the engine still running, SHOULD give you pretty impressive MPG figures for the length of the coast.
