Of the years with at least 100 tests, the 2014 model has the highest pass rate at 92% from 420 tests. The 2003 model has the lowest at 86%. The 6 point gap means pass rates vary somewhat between years, but no year is dramatically different. Newer cars usually pass more often simply because they are younger.

Mileage Across Years
