Top Gear did a couple of great fuel segments (that I know of thanks to YouTube).
1st: They took an Audi A8 TDI and attempted to get 800 miles out of 1 tank of gas. He claims that coasting in-gear opposed to in neutral uses no gas, whereas in neutral the engine has to keep itself idling. ,

Coasting in gear requires gas. No gas equals deceleration/engine braking. Most engines are tuned to accept large fuel volume variations...you tune one to idle efficiently and your Audi would win by coasting while idling...
