Low Emission Vehicle Classifications
||Transitional Low Emission Vehicle
||Required under a certain level of tailpipe emissions. Major emissions with specific standards include
non-methane organic gasses (NMOG), carbon monoxide (CO), nitrous oxide (NOx), particulate matter (PM), and formaldehyde (HCHO).
||Low Emission Vehicle
||Stricter emissions requirements than TLEV.
||Ultra Low Emission Vehicle
||Stricter emissions requirements than LEV.
||Super Ultra Low Emission Vehicle
||Stricter emissions requirements than ULEV.
||Partial Zero Emission Vehicle
||Zero evaporative emissions from fuel system, 15 year or 150K mile warranty on emission-control components, meets SULEV tailpipe emissions standards
||Advanced Technology Partial Zero Emissions Vehicle
||PZEV standards plus uses no gasoline or gets "much better fuel efficiency due to the use of hybrid electric vehicle systems."
||Transitional Zero Emission Vehicle
||Additional category for plug-in hybrids. Meets PZEV standards plus warranty traction battery for 10 years or 150K miles.
