A U.S. categorization for passenger car emissions is super ultra-low emissions vehicle (SULEV). In order to qualify, a vehicle must emit 90% fewer emissions than the typical gasoline-powered car. The SULEV standard is more stringent than the standards for LEVs and ULEVs, but it is not as harsh as the PZEVs (partial zero-emissions vehicles), which satisfy the SULEV level for tailpipe emissions but have zero evaporative emissions rather than reduced ones. Japan additionally classifies vehicles as SU-LEVs if they exhibit a 75% reduction in emissions compared to the 2005 emissions criteria. [More information required]

Very Low = Very Good
It is a step up from ULEV and stands for “Super Ultra-Low Emissions Vehicle” (Ultra-Low Emissions Vehicle). A SULEV goes far further by mandating a 90 percent reduction in tailpipe emissions, whilst a ULEV is defined as a car or truck that produces 50% fewer tailpipe emissions than the average of identical vehicles from that particular model year.
The phrase has been in use since the 1990s as a component of the Clean Air Act of the EPA, but it took more than ten years for the first one to be put into practice (the Nissan Sentra). Since then, a handful of vehicles have met the requirements, primarily compacts like the Ford Focus and the Hyundai Elantra.
SULEV—is it a hybrid?
Super Ultra Low Emission Vehicle (SULEV) Definition Experts in hybrid vehicles and alternative fuels, Christine and Scott Gable have made their own biodiesel and covered 125,000 miles on used cooking oil. The word “SULEV” stands for “super ultra low emissions vehicle.”
How can I tell if my vehicle is a SULEV?
The N51 and N52 engines are nearly identical, making it difficult to distinguish the changes visually. Checking the emissions label on the underside of your car’s hood is the simplest way to determine what engine is in it.
While the N52 will have “ULEV,” the N51 will say “SULEV.” Examining the radiator is another technique to determine the difference. The EAC (Environmental Air Catalyst) Sensor for the N51’s unit was mounted to the radiator fins. This tiny instrument keeps an eye on the radiator’s operation.
The two engines are mechanically different in a few ways. The N51 had a decreased compression ratio of 10.7:1 to 10.0:1, a three-stage variable-length intake manifold in place of a single stage, and other changes. Additionally, the cylinder heads of the two engines vary because BMW modified the combustion chamber. The ventilation systems for the crankcase and the cylinder head cover are also different.
It’s important to note that BMW tweaked both engine variants to deliver comparable output numbers.
BMW still produces SULEV?
There are presently 5 vehicles that are virtually guaranteed to have a BMW SULEV engine, according to the most recent page on Wikipedia. These include the 128i, 328i, 325i, 325Ci, and 325iT models from the BMW 1 Series and BMW 3 Series, respectively. You can always perform a quick check by opening the hood and looking at the information sticker there if you possess one of these models or any other.
The sticker should read “Vehicle Emission Control Information” and include the header “Bayerische Motoren Werke AG” (BMW, in case you didn’t know). You can see which laws, including EPA and state laws, it complies with in this statement.
If your BMW is an LEV, you’ll see something like “California: LEV II PC” underneath “Conforms to regulations” on the second row. Your car thus satisfies the requirements for low-emission vehicles. You meet this requirement if you see “California: SULEV.” It will also show whether the BMW SULEV cars you own meet the aforementioned PZEV standards (zero evaporative emissions from the exhaust).
You can consider where and when you bought the car. Your BMW almost surely comes with the N51 SULEV classification if it was purchased in California, Connecticut, Maine, New Jersey, New York, Oregon, Pennsylvania, Rhode Island, Vermont, Washington, the District of Columbia, Maryland, or Massachusetts.
The strongest classification system created to categorize zero-emission vehicles, such as all-electric automobiles, which have no emissions, is ZEV, which you won’t see on that label.
Do all BMWs have SULEVs?
Although almost all BMWs are LEVs (Low Emission Vehicles), the whole BMW model line is required by law to fulfill certain low emissions objectives. BMW has special SULEV variants in order to increase their average while selling high-performance vehicles like the M5 and X5M.
What distinguishes ULEV and SULEV from one another?
ULEV stands for ultra-low emissions vehicles. LEV certified vehicles are less clean than ULEVs. Super Ultra-Low Emission Vehicles, or SULEVs. ULEV certified automobiles are less polluting than SULEVs.
Describe Hyundai PZEV.
A vehicle that satisfies stringent requirements for environmental friendliness is referred to as a partial zero emission vehicle (PZEV). These cars have no evaporative emissions, they meet tailpipe emission limits, and the emission control parts come with very long warranties.
A vehicle that satisfies stringent requirements for environmental friendliness is referred to as a partial zero emission vehicle (PZEV). These cars have no evaporative emissions, they meet tailpipe emission limits, and the emission control parts come with very long warranties. Let’s examine the advantages and distinctive qualities of PZEVs.
How long is the warranty on SULEV?
The good news is that when BMW sold that 128i SULEV in California, it was guaranteed to continue meeting emissions rules “for the life of the automobile,” not only when it was first manufactured. A long variety of emissions-related components are covered by a fifteen-year, 150,000-mile warranty.
How powerful is the Hyundai Elantra’s engine?
The typical non-hybrid drivetrain consists of a front-wheel-drive, four-cylinder engine with 147 horsepower, and a CVT. A 1.6-liter four-cylinder engine and an electric motor are used in the hybrid variant to provide 139 horsepower. A six-speed automatic handles gearshifts in the hybrid. While none of these alternatives has a startling acceleration, we found a non-hybrid model to have a good ride and enough power for everyday city and highway driving during our test drive. The performance-focused Elantra N, which we assess separately, is the most exciting Elantra, but those who can’t quite afford that car’s price tag may want to try the more subdued N Line variant. It has a 1.6-liter four-cylinder turbocharged engine that is coupled to either a six-speed manual transmission or a seven-speed dual-clutch automatic transmission. After a brief test drive, we were impressed by the N Line’s vivacious acceleration and deft handling, which boosts the athleticism without sacrificing a harsh ride.
Is the Hyundai Elantra an eco-friendly car?
The Hyundai Elantra Sedan has received “Partial Zero Emissions Vehicle” certification from the U.S. Environmental Protection Agency (EPA) (PZEV). Only “Ultra Low Emissions Vehicle” (ULEV) standards are used to certify vehicles like the Toyota Corolla.
What does the SULEV warranty cover?
If any emission-related component on your car is broken, BMWNA will fix it or replace it. This is the DEFECTS WARRANTY for your emission control system. This is, in my opinion, a two-part warranty, one of which covers the specific components listed in the SULEV parts list and the other of which covers a failed emissions test.
How many gears does a Hyundai Elantra have in its transmission?
All Elantra versions come with a basic six-speed manual transmission and a 1.8-liter, four-cylinder engine with 148 horsepower.
What states fall under SULEV?
There is an intriguing article on SULEV automobiles having a 15 year/150K mile federal warranty on page #28 of the most recent issue of “Bimmer” magazine, which has an orange/red new M6 on the cover.
In fact, the majority of BMW dealers are unaware of this! Also remember that all MCS vehicles are SULEVs if you purchased your BMW through the military!
To determine whether an automobile is a SULEV or simply a ULEV, you must peek beneath the hood.
Four more states have been introduced for 2007 in addition to the five SULEV states that already exist: California, New York, Maine, Massachusetts, and Vermont. Connecticut, Rhode Island, Oregon, and Washington State are some of these states. (also located in the thread/link mentioned above).
Mine has the N52N and was originally purchased from PCS in K-town. I am quite certain about this because my 7-digit VIN does not have a 3-stage intake, and each VIN reader and Real OEM display a N52.
My 128i is a SULEV because that’s what our state requires. Last year, I had to acquire a software upgrade since it appeared like the PREM radiator was malfunctioning.
What exactly is ULEV mean?
In 2021, we anticipate defining a ULEV as a car or van that emits less than 50g/km CO2 in recognition of technological advancements. Pure electric vehicles get $0 Vehicle Excise Duty (car tax) in the first year, and for those under PS40,000, zero rate in subsequent years. Compared to road fuels (20%), electricity used to recharge a plug-in vehicle at home only carries a 5% level of VAT.
Which vehicles are ILEV?
A light-duty vehicle or light-duty truck that complies with the applicable ILEV standard as specified in 40 CFR 88, Subpart C, 88.311-93 is referred to as an ILEV.
What automobiles have very low emissions?
According to the NEDC test, an Ultra-Low Emission Vehicle (ULEV) is a low emission automobile or van that emits 75g/km of CO2 or less. ULEVs include plug-in hybrids, range-extended electric vehicles, and pure electric vehicles (PHEVs)
Does PZEV impact fuel economy?
The Name Isn’t About Fuel Efficiency; It’s About Emissions PZEVs should not be confused with automobiles with above-average fuel efficiency. PZEV vehicles have sophisticated emission controls, however this does not necessarily translate to better fuel efficiency. Most PZEVs have fuel efficiency ratings that are roughly average for their class.
What distinguishes a BMW N51 from a N52?
In areas of the United States with SULEV laws, the N51 engine, a SULEV variant of the N52, was offered for sale. A three-stage variable-length intake manifold (“DISA”) has been added in place of the one found on the N52 models, and the compression ratio has been decreased from 10.7:1 to 10.0:1.
Is PZEV more expensive?
Although PZEVs are believed to cost automakers between $200 and $500 more to produce, consumers typically pay no more for them than identical vehicles without the squeaky-clean certification that are created for states that have not followed California’s regulations.
