Oxides of nitrogen and carbon-monoxide don't break down easily or quickly in the atmosphere. Carbon-dioxide does. These mods to the cars might have killed efficiencies, but the output of the exhaust was much better for the earth.

Through new grades of metals, types of platings or coatings a long with better combustion control(computers), the automotive industry has made great gains in efficiency while still controlling dangerous emissions.
