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.

Tax incentives
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-emissions 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. However, the high-voltage battery warranty is limited to ten years.
