After all, diesel cars cost less to maintain, burn less fuel, and have a longer engine life. Although the pollutant emissions of a diesel engine are less than those of a gasoline one, it still emits carcinogens, nitrous oxides, and soot. Older models don’t even have the emission-control features that newer ones do.
