variable cam timing. I'm not sure what ford's version does, but in a nutshell, variable cam timing is used to boost performance in one rev range without sacrificing performance in another range.[/b]True but it depends on which cam. The VCT on the newer Contours was on the exhaust cam. It was for emissions (it got rid of the EGR). The VCT on the SVT Focus got it on the intake cam for performance.
