Many European cars rutinely do 35-45 MPG *on average* and close to

Currently California and 4 other states have emission standards that

What emission are they measuring? Surely not CO2, which is typically
much lower than with gasoline for the same power. (At least on the
kind of diesel cars we use over here).

Particulate emissions. There are some new filters that should allow
some diesel cars to meet California standards in a year or two...
