You cannot compare 2006 scores to 2014 scores, because the equations have been changed & updated many times. For example Civic CNG used to be #2 greenest car in 2011 and now it's #10. The car didn't change..... just the pollution equation.

The automatic insight doesn't have lean-burn, so it produces much much less NOx than the manual insight.
Put another way: The auto is SULEV and the manual is ULEV. So the cleaner emissions automatic get a higher score.
