I'd have to say pretty much all OBDII cars have DFCO (decelleration fuel cutoff). The engine will begin using fuel again if you press the gas pedal, shift to neutral, or drop your rpms below the idle speed as Larry said. He is also right in saying it should really only be used when you've misjudged a coasting distance, or you know you need to stop.
