AT-PZEV Emission Vehicle

Q: What does the acronym AT-PZEV represent?

A: AT-PZEV stands for Advanced Technology Partial Zero Emission Vehicle. This standard, which was created by the California Air Resources Board and adopted nationwide, certifies that vehicles have close to no tailpipe emissions, zero evaporative emissions (i.e., fuel vapor being released into the air), and have a 15-year/150,000 mile warranty on their emission system components. The Advanced Technology designation indicates that the vehicle also has Zero Emission Vehicle characteristics through the use of electric motors or alternative fuels.
