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.

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.
BMW SULEV: What Is It?
SULEV stands for Super Ultra-low Emission Vehicle. BMW and other automakers were compelled to create a technology that causes their motorized vehicles to emit fewer emissions. The advancement of this technology was influenced by this.
SULEV is another designation given to vehicles that can emit 90% fewer emissions than typical gasoline-powered cars. Of the world’s top automakers, BMW was the first to produce this kind of technology.
Not all of BMW’s vehicles are SULEV models. LEVs, or low emission vehicles, make up the majority of their fleet. The law’s low emission targets can be met by the complete BMW model lineup.
A car equipped with SULEV technology performs unaffectedly. This technique focuses on various volatile vapor emissions, such as car warranties, and the evaporative system of the fuel tank. It doesn’t execute any actions that affect engine performance.
How can I tell whether my BMW is a SULEV? Looking under the hood of your BMW can reveal whether it is a SULEV vehicle. A SULEV engine will have “SULEV” engraved into the engine block somewhere. This word is a BMW N51 engine, if you see it. Your engine is a BMW N52, but, if you see the word “LEV” in its place. You can determine whether your BMW is a SULEV or an LEV by looking up its VIN (vehicle identification number).
What Is the BMW SULEV? [Problems, Benefits, and the Warranty]
California has the strictest rules on vehicle emissions due to the state’s high pollution levels. The first automaker to use a technology that satisfies the state’s pollution standards is BMW. The name of this technique is SULEV. Exactly what is a BMW SULEV?
SULEV technology is used in the construction of BMW SULEV, or Super Ultra-low Emissions Vehicle, vehicles. With the use of this technology, automakers hope to reduce the amount of pollutants that their vehicles produce by 90% compared to standard gasoline-powered automobiles.
BMWs do not all operate as SULEVs. LEVs make up the majority of BMW vehicles. LEV is an abbreviation for low emission vehicle. It’s important to note that most BMW automobiles meet the regulator’s low-emission requirements.

A SULEV engine is what?
Super Ultra Low Emissions Vehicle, or SULEV, is an emission category that was first established under the California Air Resources Board (CARB). The N51 and particular other less-polluting engines were created as a result of California legislation that requires a set number of vehicles sold by a manufacturer to adhere to SULEV rules.
A ULEV-compliant engine emits less than 2.1g/mi of CO (carbon monoxide) and 0.07g/mi of NOx when put through the FTP-75 cycle, a set of emission tests meant to replicate city driving for a long time (nitrogen oxides).
A SULEV-compliant engine, on the other hand, will emit less CO and NOx than 1.0g/mi and 0.02g/mi, respectively. These figures pertain to an engine that is either 11 years old or has driven 120,000 kilometers. A SULEV engine is often thought to be 90% cleaner than the average engine.
For BMW, what does SULEV mean?
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 can I tell whether my BMW 328i is a SULEV?
It has actually gotten harder to tell what’s inside the hood now that many SULEV cars have the N51 and others bear the N52. It was simpler to identify the engines on earlier models that used the M54 and M56 SULEV. There were important visual cues, especially on the valve covers. On the other hand, the N51 SULEV vehicles and N52 engines have extremely similar appearances.
If you want to be sure, you can check the label mentioned above beneath the hood. If it says SULEV, then the engine is the N51; if it says LEV, then the engine is the N52. There are further methods, such as checking your BMW car identification number (VIN). The engine type and attributes are indicated by the numbers 4 through 8 in this lengthy number. The VIN can be found in numerous locations under the hood as well as on the driver’s side of the dashboard, which can be accessed through the windshield.
Hopefully, the SULEV requirements will enable your BMW to contribute to the solution rather than the issue of the environment. To determine whether you are a low emission vehicle or a super-low emission vehicle, look at the label beneath the hood.
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.
The BMW 328i is quick.
The 328i’s peak speed is electronically capped at 130 mph. The 335i accelerates from 0 to 60 mph in just 5.1 seconds with the automatic transmission and 5.4 seconds with the optional manual transmission.
What does a BMW 328i have high mileage?
When properly maintained and driven cautiously, the BMW 3 Series can endure between 200,000 and 250,000 miles. It will last roughly 13 to 17 years if you drive 15,000 miles per year before needing expensive and unnecessary repairs.
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 are typical BMW 328i issues?
- Timing-chain problems The most frequent issues with the 2014 BMW 328i are those impacting the timing chain.
- Fuel system malfunction.
- Electrification issues.
- Speed control issues with vehicles.
- A/C and heating system overheating.
- Oil Spills
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!
How far can a 328i drive?
But how far is a BMW 3 Series capable of traveling? When maintained properly, you can anticipate your 3 Series to endure between 200,000 and 250,000 kilometres.
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.
Which BMW is the most dependable?
When it comes to the creation of sport sedans, BMW has established the benchmark for premium vehicles with the E90 330i that Acura and Volvo aspire to match. The BMW E90 330i is your best option if you’re looking for a sedan that provides the ideal balance of functionality and performance without sacrificing stability and comfort.
The BMW E90 330i is one of the most popular luxury vehicles in the United States and is not only the best-selling model in the 3 Series. It also sold over 336,232 units. Even in the mid-size luxury automobile category, the BMW 3 Series received the Top Safety Pick designation in 2006. The best car options in terms of driver injury prevention and driver restraint features are highlighted by this award.
