The emissions characteristics of that engine pushing a Vanagon will be
different than coasting with a Focus. Especially the production of NOx.
Even changing tire sizes and gear ratios change the emissions profiles.
True compliance is not as easy as it appears. When you do get emissions
testing, keep in mind that all programs can only find gross failures.
Except for CO2, the goal is near "0" of all the other pollutants. Being
allowed some 200ppm of unburned hydrocarbons at idle is still a bad deal.

What is the deal with Zetec and California?  Surely the Ford Focus is
sold there?  I'm completely ignorant of emissions laws and testing
since we don't have any here in Indiana, but if the Zetec is OK in a
Focus then why not a Vanagon?  Is there some restriction on it not
being an original factory configuration?
