it's kind of a joke for the Civic people. Zetec (commonly called Z-Tech in the honda community) is nothing more than the name of the engine. Honda people however, think it's a secret weapon or something for some reason and always asks when it kicks in or whatever. The joke is the Focus guy's answer: "Zetec kicks in when I turn the key." It's just funny to see their reactions.
And Ford does have a Europe division. This tag is a tribute to the genius of bringing over a car virtually unmodified, something Ford America is too stupid to ever do again. Look up the Focus on Wikipedia, Ford Europe 1998, to America 2000, best selling car in the world I think.
