ZEV
Zero Emission Vehicles have zero tailpipe emissions and are 98%
cleaner than the average new model year vehicle.
AT PZEV
Advanced Technology PZEVs meet SULEV tailpipe emission standards,
have a 15 year / 150,000 mile warranty, have zero evaporative
emissions and include advanced technology components. For example,
a plug-in hybrid or a compressed natural gas vehicle would qualify
in this category.
PZEV
Partial Zero Emission Vehicles meet SULEV tailpipe emission standards,
have a 15 year / 150,000 mile warranty and have zero evaporative
emissions.
SULEV
Super Ultra Low Emission Vehicles are 90% cleaner than the average
new model year vehicle.
ULEV
Ultra Low Emission Vehicles are 50% cleaner than the average new
model year vehicle.
LEV
Low Emission Vehicles are the least stringent emission standard
for all new cars sold in California in 2004 and beyond.
NOTE ON TRUCKS,
VANS AND SUVS:
In 1998, the California Air Resources Board extended the passenger
car emission standards to heavier sport utility vehicles and pickup
trucks (with gross vehicle weight up to 8,500 pounds), which formerly
had been regulated under less stringent emission standards (LEV
I). The new regulations (LEV II) provide a transition period between
2004 and 2007 for manufacturers to meet the new standards for
trucks, vans and SUVs. Consequently, a portion of the large vehicle
fleet will meet less stringent emission standards (LEV I) until
2008.
For the consumer this means that until 2008, larger vehicles with,
for example, a SULEV emissions rating could pollute up to ten
times more than a passenger vehicle with that same rating.
