SULEV stands for Super Ultra Low Emissions Vehicle, despite sounding like a Russian missile brand. The California Air Resources Board (CARB) designation scheme for the new generation of hybrid and all-electric automobiles, which of course went beyond the conventional “low emission” bracket, gave life to this relatively new category of vehicle as a directive in the Golden State.
Although many BMWs now fulfill the standards for super ultra low emissions, the majority of them would still be classified as “LEVs,” or low emission vehicles. By definition, a vehicle must emit 90 percent fewer emissions than the typical gasoline-powered car in order to comply with SULEV regulations.
That makes it a much harsher standard than the LEV moniker, which is becoming more widespread as automakers scramble to meet legislated emission level objectives. The PZEV (Partial Nil Emission Vehicle), which has the same basic criteria for tailpipe emissions as SULEVs, is much stricter, but evaporative emissions must be zero instead of only “reduced.”

Exhaust
SULEV vehicles have completely different exhaust systems than conventional vehicles. BMW went ahead and added a catalytic converter to the exhaust manifold’s ultimate end. They’ve also added dual downstream cats and upstream oxygen sensors to some vehicles, including the E46 3-series.
These automobiles’ cats also need to warm up before they can perform at their best. When the entire system reaches the ideal operating temperature, they are designed to burn the most remaining particles.
Which States Offer N51 BMWs for Sale?
The LEV II Standards, which have since been adopted by additional states, include LEV (Low Emissions Vehicle), ULEV (Ultra Low Emissions Vehicle), SULEV (Super Ultra Low Emissions Vehicle), and PZEV (Partial Zero Emission Vehicle). Arizona, Connecticut, Maine, Maryland, Massachusetts, New Hampshire, New Jersey, New Mexico, New York, Oregon, Pennsylvania, Rhode Island, Vermont, Washington State, and Washington, D.C. are a few of these.
Your E9x 3-Series or another BMW generally powered by a N52 engine is probably powered by a N51 if it was acquired in one of these states.
What does SULEV on a BMW stand for?
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]
How do I find out if the SULEV is in my BMW?
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.
Are BMW SULEV prices higher?
However, it’s not so straightforward because there are other factors at play besides just the higher cost of acquisition. The SULEV/PZEV automobiles are more expensive to make and to fix. The components of “California emissions” are highly developed, intricate, and interrelated. For instance, the gasoline tank on a 2013 BMW 128i SULEV is hermetically sealed.

What does the acronym BMW 328i mean?
Balqy Firman Syah, one. Look at the second and third numbers in any BMW’s name to find out how big the engine is. The “25” in the BMW 325 indicates that the vehicle has a 2.5-liter engine, whereas the “28” in the BMW 328 indicates that the vehicle has a 2.8-liter engine.
What does the SULEV warranty cover?
Previous repairs covered by the warranty included the replacement of the valve cover, each of the six coils, the fuel pump, the gasoline tank, and the fuel line. Recall that the SULEV warranty has two parts: one that covers the list of components and one that protects you in the event that an emissions test is unsuccessful.
What model of BMW has a N52 engine?
One of the most popular and successful inline-6 engines made by BMW is the N52. The N52 was primarily used in the E90 325i, 328i, and 330i as well as the E60 525i and 528i models. It was also used in a number of other vehicles, such the 128i, X1, and Z4, to name a few. From 2004 until 2015, the N52 was manufactured before being superseded by the turbocharged N20 engine. The M54, which was utilized in a number of E36, E39, and E46 models, was replaced by this model.
BMW was able to refine several parts of the engine during the course of manufacture thanks to the lengthy production history. Even top 10 best engines awards were given to the engine in 2006 and 2007. The N52 still experiences a good number of typical dependability issues, though. We’re going to talk about the top 7 engine problems that the N52 has.
The N52 has proven to be more dependable than its larger sibling, the N54, thanks to the engine design. Drivers of the N52 won’t have to worry about these two typical N54 problems because the N52 lacks an HPFP or direct injection. You may read our tutorial on N54 engine issues to compare the two as well!
Which motor powers my BMW 328i?
The BMW N52 engine’s specifications for the E90 and E92 328i are as follows:
The 3.0L inline-6 N52 engine of the 328i is naturally aspirated. To assist keep weight off the front axle, it incorporates a block made of lightweight magnesium and aluminum. Additionally made of aluminum, the head has 24 DOHC valves. Electronic throttle control, double-VANOS, and valvetronic are features of the BMW N52 328i engines. Better performance and fuel efficiency are delivered thanks to all of this technology.
What kind of motor powers the 2011 BMW 328i?
The 3.0-liter inline-6 engine in the BMW 328i sedan ($33,150) produces 230 horsepower. With the 328i xDrive sedan’s permanent all-wheel drive ($35,150), xDrive is added. Standard transmissions include a 6-speed manual, and most models may be ordered with a 6-speed Steptronic automatic for $1,375.

My BMW has a N51 or N52?
From 2006 to 2015, the engines were put into a wide range of various BMW automobiles. They can be found in the Z and X series, as well as the 1, 3, and 5 Series. Being aware of the type of displacement you’re dealing with is one simple technique to identify which engine you don’t have. N51 was only offered as a 3-liter engine, hence any inline-six of this generation that is 2.5 liters will be N52.
Following that, the following are some of the key variations between the two engines:
- Both the N52 and the N51 use aluminum cylinder heads, but the N51’s is unique due to changes made to the combustion chamber to comply with SULEV regulations. They cannot be switched out.
- Cylinder Head Cover: The cylinder head cover on the N51 is made of plastic and has integrated crankcase ventilation; the one on the N52 is made of magnesium.
- External crankcase vent valve with cyclone separator is a part of the N52’s crankcase ventilation system. The N51 contains an integrated vent valve, a labyrinth, and cyclone oil separation, as was already noted.
- On more powerful variants of the N52, the intake manifold is made of plastic and has a 3-stage DISA valve. The 3-stage DISA unit on N51 is utilized to account for various compressions.
- Piston/compression Ratio: For N52, this ratio is 10.7:1, but for N51, it is 10:1.
- The N51 utilizes a digital hot film meter, whereas the N52 features an analog version.
The problem is that despite all of these distinctions, it’s impossible to tell these engines apart by just opening the hood. Not like the M56 and M54 generations, for example. You could immediately distinguish the M56 SULEV from the M54 thanks to aesthetic differences.
But there is a solution. Examining the car emissions plate under the hood is the quickest way to figure out which engine you’re working with. The pertinent information can be found in the third row, on the left side of the plate. The N51 has a SULEV tag, but the N52 will be labeled as an LEV.
How can I tell whether my BMW has an all-wheel drive system?
Check your door jamb or the hood for a sticker similar to this one: Your model should be there (top left). can simply phone any dealership, provide them with your VIN number, and inquire as to what model it is.
Where can I obtain the code for my BMW engine?
The year, make, and model of your car are always requested at auto parts retailers. That is not difficult. However, they also require information regarding your engine. Don’t know exactly what’s inside or what year it is? Everything is contained in the engine code (also known as the engine number) and vehicle identification number (VIN). The VIN is located on the driver’s side of your windshield in the lower corner.
The model year is indicated by the tenth number from the left, while the engine code is indicated by the eighth number. You only need to mention those two characters to the store clerk to get started.
Now that you know where to look for your VIN engine code, find out what a mechanic thinks these odd automobile noises indicate.
