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. For automobiles that demonstrate a 75% reduction in emissions compared to the 2005 emissions regulations, Japan also offers the SU-LEV rating. [clarification needed]

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.
SULEV: What Does It Mean? Learning About Low-Emissions Vehicles
Have you ever wondered what exactly the phrase “SULEV” at the bottom of a vehicle’s window sticker meant? Or perhaps it was a badge on a car’s trunk or an SUV’s hatch at a dealership? This abbreviation, which gives a glimpse into the technologies behind the eco-friendly progress of contemporary automobiles, really describes the quantity of emissions produced by a vehicle in normal operation.
Describe 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.
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 is protected by the BMW SULEV warranty?
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 are some typical BMW issues?
- Engine Cooling Unit. Overheating is a problem that many BMW owners frequently experience.
- Oil Spills.
- Under Braking, the steering wheel vibrates.
- Tail Lamp Unit
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.
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.

What is a BMW’s typical lifespan?
The durability of the car is undoubtedly one of your first concerns if you’re thinking about joining the club of “Bimmer” owners.
You don’t want to purchase a car that will break down after a year or two, leaving you with the choice of paying for expensive repairs or purchasing a new vehicle. How long do BMWs last, then?
BMWs may live more than 15 years with proper maintenance. BMWs with proper maintenance may travel far over 200,000 miles, and in certain cases, over 250,000 miles. Although this is significantly less common, certain BMWs have reportedly lasted beyond 300,000 kilometers.
In the USA, most people travel 13,467 miles (21,673 km) annually, giving cars an average lifespan of at least 15 years.
BMWs can survive longer because their average annual mileage tends to drop as they age because of this.

A low emission car in the UK is what?
A low emission vehicle (LEV) is currently defined by the UK Vehicle Certification Agency as one that emits less than 100g of CO2 for every kilometer (0.6 miles) driven. This includes zero emission cars (ZEVs) that emit no CO2 from their tailpipes and ultra-low emission vehicles (ULEVs) that emit less than 75g of CO2 per kilometer.
The bulk of newly registered cars in 2019 (92.1%) were either gasoline or diesel vehicles. But from 2.8% in 2015 to 7.9% in 2019, the percentage of brand-new hybrid and electric vehicles registered for the first time rose. These Department of Transportation figures may not exactly fit the definition of an LEV used above because they are classified by fuel type rather than emission levels.
The Society of Motor Manufacturers and Traders has released statistics demonstrating an increase in the market share of battery electric vehicles from 6.7% in September 2020 to 15.2% in September 2021.
A recent ONS study found that 44% of all people who do not already drive an all-electric car are likely or very likely to do so within the next ten years. This indicates that attitudes toward electric cars are also evolving.
This analysis focuses on the most recent information on companies operating in the LEV industry up to 2019 (and in particular on companies with 250 or more employees). As a result, it doesn’t take into account the consequences of any recent announcements.
