What does Zetec mean on a Ford?

Ford's Zetec branding began on a series of four-cylinder engines that began production in the early 1990s. Today, Zetec refers only to a level of trim on certain Ford cars in Europe — the Zetec line typically has a more sporty design than the base-level trims.

It's just the name of the Ford line of 4 cylinder engines. It was Zeta before until Ford was sued for using that name as it was trademarked already. Alex
