RE: What is the difference between the 2.0L and 2.3L engines on the focus?l
From late 03 on, the ZX3 or sedan could be had with the 2.3l Duratec as the optional motor. Most dealers had the 2.0L Zetecs shipped as that was the standard and the Focus is thought of as more a commuter gas miser. Cheap prices make a LOT of sales. For 05, most of the motors are the 2.3LDuratec, with some 2.0Zetecs still out there.
