(Redirected from SULEV)
U.S. classification for passenger vehicle emissions

Super ultra-low emissions vehicle (SULEV) 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 (low emission vehicle) and ULEV (ultra-low-emission vehicle), however not as strict as PZEV (partial zero-emissions vehicle) 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

Honda Insight

Examples of vehicles delivering SULEV emissions performance include:

Tax incentives

In California, manufacturers of SULEVs can be given a partial credit for producing zero-emission vehicle (ZEV) and so a vehicle of this type can be administratively designated as a partial zero-emissions vehicle (PZEV). 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/150,000 mi (241,402 km) warranty on its emission-control components.

In the case of hybrid vehicles this warranty is extended to the electric propulsion components (electric motor/generator/starter, battery, inverter, controls) and their mechanical interface to the driveline. However, the high-voltage battery warranty is limited to ten years (but still 150,000 miles).
