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.
What is a BMW SULEV?
BMW refers to its vehicles with all-wheel drive as an option rather than the more common rear-wheel drive under the moniker xDrive. In order to improve traction and provide the driver with superior control in more difficult driving circumstances, consider the 328i xDrive as an example. This vehicle can transfer power to both the front and rear wheels.
All-wheel drive has typically been associated with less environmentally friendly vehicles like SUVs, however your BMW can come in both xDrive and SULEV versions. Some buyers of the xDrive who discover it to be a SULEV may decide to modify it to turn it into a more potent type. They might not consider a SULEV BMW to be a true performance BMW.
The N51 SULEV is now nearly identical to the N52 in many ways because to technological advancements and general improvements. BMW SULEV engines are by definition unable to match the performance of the M4 or X5M engines, but those bearing the M designation are designed for performance on the racetrack.
To ensure that enough of BMW’s range can comply with the increasingly stringent emissions regulations and prevent the imposition of costly government fines, a SULEV engine is designed. Therefore, SULEV vehicles are a crucial component of any current lineup for a performance brand like BMW.
How can you tell if a 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.
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.
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.”
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 can I tell whether my BMW 328i is a SULEV?
With the initial E46 3-series vehicles, it is now simpler to determine whether your car is a SULEV or not. You only need to open the hood and take a quick glance at the valve cover if you have those. Your car is a SULEV if it is made of aluminum.
With more contemporary models such as the E90, F30/31 3-series, and others, there are less visual clues. The simplest method to make sure is to examine the engine bay for the emissions tag. Depending on the vehicle you drive, that tag will either explicitly declare that it is a SULEV or will specify the engine type. You can check the internet list of super ultra-low emission vehicle engines to see if the engine in your automobile is included if you know what it is.
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.
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.
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.
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.
ULEV 2: What does it mean?
The following low-emission vehicle requirements, which are stricter than the phase I criteria that were previously in effect in California, will be phased out by the model year 2020 when all new vehicles must be certified to the new LEV III guidelines:
- Low-emission vehicle, or LEV II, is the phase II LEV standard with the laxest requirements. NOX emissions are one-fourth that of a vehicle with an LEV I certification.
- Ultra-low-emission vehicle type II (ULEV II), a mid-level phase II LEV standard Nearly 50% less hydrocarbon and carbon monoxide emissions are produced than by a vehicle with an LEV II certification.
- A Californian requirement even stricter than ULEV II, SULEV II stands for super-ultra-low-emission vehicle and features substantially fewer NOX emissions and more robust control systems.
- PZEV: a partially zero-emission vehicle that complies with the SULEV standard and also has nearly zero evaporative emissions and an emission control system with a 15-year/150,000-mile warranty.
- ZEV stands for zero-emission vehicle, which is a California law that forbids any tailpipe emissions.
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.
Does PZEV impact fuel economy?
Don’t confuse PZEVs with vehicles that score above-average for fuel efficiency; the name refers to emissions. 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 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)
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.
Are all new autos legal in all 50 states?
Yes, as you cannot hold a dealership responsible if you did not request this. I’m hoping that makes sense. You need to get a printout of your order, including the items you choose.
That’s exactly what I’m saying, to be clear. Make sure the dealer orders it with the appropriate gear for you. Dealers who aren’t accustomed to doing it, in my experience, aren’t really aware of the possibility. They don’t typically pay attention to it. Make sure they understand that California emissions must be ordered and that if they don’t, you won’t take the vehicle.
As long as the car is equipped properly, there shouldn’t be an issue. Look below.
NOTE: This is NOT the same as complying with California emissions laws. Every Ford is “50 state” legal. The problem is that the term has a bit of a misleading connotation. “50-state compliance” refers to vehicles that have emissions that comply with federal standards. Therefore, rather than implying that the vehicle is legal in all 50 states, the word actually signifies that they comply with federal regulations.
Thus, even while all Fords comply with federal regulations, not all of them do so to the strict “California” standards. California is one of a total of 13 states that have this strict criteria. Therefore, “50-state” actually refers to 37 states. I believe that there is a California emission option box that customers can click when ordering. However, dealers who don’t deal with that on a regular basis could not be aware of this distinction (I’ve seen this previously). There shouldn’t be a problem if they order your vehicle with it. However, since it is doubtful that their goods was arranged appropriately, you cannot purchase directly from them.
It then becomes a question of whether or not they are willing to place an order for a buyer from outside the state with California emissions and run the danger of being forced to use them. I doubt that their typical customer would be able to tell the difference, but who knows?
EDIT: I did some research. A non-compliant vehicle is acceptable for entry if:
1) Its mileage exceeds 7,500 miles
2) You purchased it when you were living outside of New York, but you have subsequently moved here.
3) You had to purchase a vehicle while driving to replace one that had been damaged, wrecked, etc.
4) You inherited the car from a non-resident.
5) You are a member of the military.
6) The car is an officially licensed emergency vehicle.
