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 Emissions Vehicle), however not as strict as PZEV (Partial Zero Emission Vehicle) which meets the SULEV standard for tailpipe emissions, but has zero instead of reduced evaporative emissions.
Examples of vehicles delivering SULEV emissions performance include:
- Honda Accord 2000-? 
- Honda Insight (CVT transmission models only)
- Honda Civic Hybrid CVT transmission models only, AT-PZEV available in certain states
- Honda Civic GX Natural Gas
- Honda CR-Z (AT-PZEV)
- Toyota Prius
- Ford Focus SULEV 
- BMW SULEV 128i, 328i, 325i, 325Ci, and 325iT
- Subaru PZEV Vehicles beginning with 2008 year models including Forester, Outback, Impreza and Legacy
- Chevrolet Volt
- Hyundai Elantra
- Lexus CT200h
- Honda Clarity PHEV 2018 - LEV3-SULEV20
- Kia Forte
- Volkswagen Jetta
- Mini Cooper Hardtop 4-Door 
- Toyota RAV4 Hybrid
- Pontiac Grand Prix, 3800 V6 equipped vehicles beginning with the 2006 model year
- Toyota Highlander Hybrid
- Chrysler Pacifica Hybrid

In California, manufacturers of SULEVs can be given a partial credit for producing a Zero Emission Vehicle (ZEV) and so a vehicle of this type can be administratively designated as a Partial Zero-Emission 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 - potentially a distinct advantage to the owner of such vehicle.
