Many people are saying that it's possible. Including Jeremy Clarkson, who I believe said the same thing during an episode of Top Gear. But the way they say it is quite ... quirky. So I shall present the argument as best as I can:
When a car is approaching a red light or stop sign or is otherwise in need to decelerate, it is better to stay in gear than to shift into neutral. Because if you simply stay in gear and let off the gas pedal, then the engine is consuming no fuel while if you put it in neutral then the engine must use some fuel to prevent stalling.
I don't believe that is a correct statement. The engine management system is not smart enough to cut off fuel flow because it somehow "knows" that the driver wants to stop. And also if NO fuel is being used, then how is the engine running at all? Are they saying that for a brief period of time all those 4, 8, 12 pistons can still move up and down with enough ferocity to keep the crank going with no combustion????
