A new study led by researchers at the University of Michigan compared regulated and unregulated emissions from both light-duty passenger car (1.7 L/2002 calibration and 6.4 Unregulated pollutants also include ozone precursors and bioaccumulative and toxic compounds. For the study, they used a GM 2002 1.7
