No. metaphors connote equivocality between two things by likeness without the blatancy of using words like "like." "gunned the engine" is more of a figure of speech -- literally it is a verbalization of a noun to describe and action taken with an engine. But to say "the engine is a gun" is a metaphoric description of the engine.
An explicit metaphor is a metaphor that is fully explained in great detail. Unlike an implicit metaphor, which the meaning has to be implied.

If someone is "gunned down" it means they were shot, and most likely died as a result of the gunshot wound(s).
Literally, it would mean being shot with a machine gun: The soldier machine-gunned the enemy. Figuratively, it can relate to things making the same sound as a machine gun (a woodpecker machine gunned in the distance), or things coming at you too rapidly to deal with them individually: they machine-gunned suggestions at her.
