Super ultra-low emission vehicle


Super ultra-low emissions vehicle is a U.S. classification for passenger vehicle emissions. The classification is based on producing 90% fewer emissions than the average gasoline powered vehicle. The SULEV standard is stricter than the standard for LEV and ULEV, however not as strict as PZEV which meets the SULEV standard for tailpipe emissions, but has zero instead of reduced evaporative emissions. Japan also offers an SU-LEV classification, for vehicles that show a 75 percent reduction in emissions vis-à-vis the 2005 emissions standards.

Examples

Examples of vehicles delivering SULEV emissions performance include:
In California, manufacturers of SULEVs can be given a partial credit for producing a Zero Emission Vehicle and so a vehicle of this type can be administratively designated as a Partial Zero-Emission Vehicle. In order to qualify as a PZEV, a vehicle must meet the SULEV standard and, in addition, have zero evaporative emissions from its fuel system plus a 15-year/ warranty on its emission-control components.
In the case of hybrid vehicles this warranty is extended to the electric propulsion components and their mechanical interface to the driveline - potentially a distinct advantage to the owner of such vehicle.
