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. [1] 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. [2] [ irrelevant citation ] 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 of vehicles delivering SULEV emissions performance include:
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-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).

The Toyota Prius is a compact/small family liftback produced by Toyota. The Prius has a hybrid drivetrain, combined with an internal combustion engine and an electric motor. Initially offered as a four-door sedan, it has been produced only as a five-door liftback since 2003.
The California Air Resources Board is an agency of the government of California that aims to reduce air pollution. Established in 1967 when then-governor Ronald Reagan signed the Mulford-Carrell Act, combining the Bureau of Air Sanitation and the Motor Vehicle Pollution Control Board, CARB is a department within the cabinet-level California Environmental Protection Agency.
The Honda Insight is a hybrid electric vehicle that is manufactured and marketed by Honda. Its first generation was a two-door, two passenger liftback (1999–2006) and in its second generation was a four-door, five passenger liftback (2009–2014). In its third generation, it became a four-door sedan (2018–2022). It was Honda's first model with Integrated Motor Assist system and the most fuel efficient gasoline-powered car available in the U.S. without plug-in capability for the length of its production run.
A partial zero-emission vehicle, in the United States, is an automobile that has zero evaporative emissions from its fuel system, has a 15-year warranty on its emission-control components, and meets SULEV tailpipe-emission standards.
A zero-emission vehicle (ZEV) is a vehicle that does not emit exhaust gas or other pollutants from the onboard source of power. The California definition also adds that this includes under any and all possible operational modes and conditions. This is because under cold-start conditions for example, internal combustion engines tend to produce the maximum amount of pollutants. In a number of countries and states, transport is cited as the main source of greenhouse gases (GHG) and other pollutants. The desire to reduce this is thus politically strong.
The Toyota RAV4 EV is an all-electric version of the popular RAV4 SUV produced by Toyota until 2014. Two generations of the EV model were sold in California, and to fleets elsewhere in the US, with a gap of almost ten years between them.

The Japan Mobility Show (ジャパンモビリティショー), called Tokyo Motor Show (東京モーターショー) (TMS) until 2019, is a biennial auto show held in October–November at the Tokyo Big Sight, Tokyo, Japan for cars, motorcycles and commercial vehicles. Hosted by the Japan Automobile Manufacturers Association (JAMA), it is a recognized international show by the Organisation Internationale des Constructeurs d'Automobiles, and normally sees more concept cars than actual production car introductions, which is the reason why the automotive press sees the show as one of the motorshow's big five.
The Los Angeles Auto Show, also known as the LA Auto Show, is an auto show held annually at the Los Angeles Convention Center in Los Angeles, California, United States. It is open to the public for ten days, filling 760,000 square feet (71,000 m2) of exhibit space. Since 2006 the event is held in November or December.
An ultra-low-emission vehicle (ULEV) is a motor vehicle that emits extremely low levels of motor vehicle emissions compared to other vehicles. In some jurisdictions it is defined in law; low and ultra low emission vehicles may be given tax or other advantages, while high emission vehicles may suffer restrictions or additional taxation.
The Honda CR-Z is a sport compact hybrid electric car manufactured by Honda and marketed as a "sport hybrid coupe." The CR-Z combines a hybrid gasoline-electric powertrain with traditional sports car elements, including a 2+2 seating arrangement and a standard 6-speed manual transmission.
