The N54B30 was mentioned previously. With regard to the model names we were describing, this code didn’t make sense. That is so because it is not a model name for a BMW. In actuality, it is an engine code, and each digit stands for a distinct component of the engine.
The initial letter, an N, stands for the family of engines that BMW uses. It will be one of the following six: M, N, B, S, P, or W. The W is the only one not built by BMW. The M range of engines was produced up to 2001, and the N range later. Modular engines called B engines have been developed since 2013. P engines are racing engines for motorsport, while S engines are production engines for motorsport. W is a category for outside engine providers.
The first number, the second component of the BMW engine code, can alternatively be one of the following six: 3, 4, 5, 6, 7, or 8. These show how many cylinders there are.
The engine variety is indicated by the third component of the code, the second number. Up to ten reasonably significant alterations, with 0 representing the original, are possible for the engine (marked as 1-9 in the code).
The last two figures represent the engine size multiplied by 10. Thus, the N54B30 from our earlier example would have a 3.0L engine.
Our BMW engine code’s optional addendum “TU,” which stands for “technical upgrade,” makes up the sixth component. These improvements are not as significant as engine variations and do not necessitate a new numerical categorization for the engine. Consider the iPhone 6 and iPhone 6s as the same model, but with Siri on one and not the other.

Codes for BMW Engine Identification
Since 1978, all BMW engines sold in the US are covered by this information. On the engine block are codes that can be used to determine the engine’s displacement size, country version, fuel system, revision state, and serial number.
The engine block may have a variety of codes imprinted into it. These symbols stand for:
1. ENGINE CODE AND NUMBER:
Engine No. :
An eight-digit engine number, made up of two sets of four digits, will be assigned to a series production engine. Information on the assembly line and the serial number of the engines produced each day is contained in the first block’s first four digits. The factory code and manufacturing day are displayed in the second block.
An engine designation code is stamped in series manufacturing engines in addition to the eight-digit engine number for model identification. With the aid of Chart 1, these numerals can be decoded.
Note: The codes for new/remanufactured engines obtained from the parts department are different from those for production engines and should not be confused with them. This code (see list below) contains details on the nation version, change status, fuel system, and number of cylinders for engines fitted during production:
The information for the remanufactured engine is now die-stamped in the same location as for new engine identification after the digits for the original engine data were ground off.
Similar to engines in series production, the 8-digit engine number is made up of 2 blocks of 4 numbers, however they represent distinct information:
- Information on the daily production of engines is given in the first block of four digits.
- The month and year of production are also included in the second block, along with a code for either a new or remanufactured engine.
Engine Code
codes applied to engines in series production:
Chart 2 for engines of the U.S. version can be used to decode these figures. The engine’s precise part number is identified by this decoding.
Identification of the engine numbers’ shape and appearance
The 5-character vin engine code and the actual engine numbers make up the engine N. (8 alphanumeric characters).
On more recent models, everything might be on a single line. The engine code matches the engine designation on the factory plate exactly (identification plate).
Meanings of BMW Engine Codes and Their Location
Finding out what type of engine is in front of you and whose automobile it belongs to will be quicker and easier if you comprehend the logic behind the labels used on engines.
BMW engines are identified by a sequence of numbers and letters that correspond to the engine’s technical specifications. This set may appear to have no logic and that the numbers are random at first glance. Contrary to popular belief, the VIN Number (also known as the vehicle identification number) is used by manufacturers to identify the version of a vehicle it is.
The upper-left corner of the tables below shows an example of the engine code. The symbol whose meaning is clear from this table is marked in red.
Understanding BMW Engine Names
In order to distinguish engines throughout engineering and production, automakers frequently give them internal nomenclature designations. Typically, they are just a list of letters and numbers that the average consumer cannot understand. But as Engineering Explained’s Jason Fenske notes in his most recent video, these codes typically include a wealth of information. BMW is a perfect example because it has been calling its lineup of engines the same way for decades. Here is a guide to understanding BMW engine code names.
I’ll give you an example. The S63B44T4 engine in the 2018 M5 is a reliable one. Here is the meaning of all those letters and digits.
The first letter indicates the “engine family” that this powerplant belongs to. In this instance, “S” stands for an engine created by BMW’s M division. Given that the engine is from an M5, this makes sense. The majority of standard, non-M BMW engines have a “N” designation if they were created after 2001, and a “B” designation for those created after 2013. If a BMW engine has a “W,” it was not produced by BMW but rather by an outside supplier.
6: The second character is a number that denotes how many cylinders the engine has. Don’t be deceived; occasionally, the digit doesn’t match the number of cylinders. For instance, this “6” actually denotes a V8 engine. Engines with three or four cylinders are designated as 3 or 4, accordingly. Here, the numbers 7 and 8 designate V12 and V10 engines, respectively.
The engine has undergone three upgrades, as shown by the third character. For instance, if this number were “0,” the original design would have been indicated. The “3” above denotes that this engine has three enhanced features, such as sequential turbos or direct injection.
B: The engine’s fuel type and whether it is positioned longitudinally or transversely in the vehicle are indicated by the fourth character. The “B” in this case indicates that it is positioned longitudinally and runs on gasoline. The engine would run on gasoline and be positioned transversely if it had a “A” designation. Diesel engines are denoted by letters “C” and “D,” while electric motors are denoted by letter “E.”
44: The displacement is represented by these two digits. Here, the “44” refers to 4.4 liters. This would be a 5.0-liter engine if it were to say “50.”
T: The engine’s “performance class” is indicated by this character. From lowest (K), lower (U), middle (M), upper (O), top (T), and super are the options (S). Ironically, this engine is in the second-highest category, which is the top class.
4: The very final character stands for the number of redesigns the engine has undergone during the course of its existence. It would be a new engine that has not yet been changed if this number were “0.” The engine in question is in its fifth generation and has had four modifications, as indicated by the “4”.
TU: The final two characters of some older engines are “TU,” which stands for “technical upgrade.” The engine has changed significantly from the previous edition, which is exactly what it sounds like.
What number is the BMW engine?
Engine Codes for BMW In actuality, it is an engine code, and each digit stands for a distinct component of the engine. A BMW engine code consists of five mandatory components and one optional component. The initial letter, an N, stands for the family of engines that BMW uses. There are six possible letters: M, N, B, S, P, or W.
How powerful is a BMW’s engine?
BMW is well recognized for its history with inline-six (straight-six) engines; in spite of most other manufacturers converting to a V6 architecture, BMW still uses this layout today. BMW also manufactures the more popular inline-four and V8 engine configurations, as well as inline-3, V10, and V12 engines on occasion.
Although prototype V16 engines have been built, they have not yet entered production. These prototype engines were the 9.0 liter 2004 Rolls-Royce 100EX engine and the 6.7 liter 1987 BMW Goldfisch V16 engine.
What BMWs are powered by the 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 of BMW’s engines is best?
The M88, which powered BMW’s M1 supercar, was the company’s first M engine. It could produce somewhere between 215 and 282 horsepower with a redline of 6,500 RPM, which was a major thing when it was developed in the late 1970s. Additionally, it was employed in the BMW 3.0 CSL, which competed in the Group 5 race series and produced more than 800 HP at 9,000 RPM.
It was a strong engine that made one of the most beautiful engine sounds ever.
What BMW engine has the most power?
The most potent engine installed by BMW M GmbH is found in the BMW M5 CS. The 4.4-liter V8 with M TwinPower Turbo technology produces a peak torque of 750Nm between 1,800 and 5,950 rpm and 635 horsepower at 6,000 rpm.
Which BMW motor is the most dependable?
BMW is known for producing high-end vehicles. You could be wondering if they are trustworthy, and the answer is that they are absolutely trustworthy. Even though they have quite high price tags, they are still worth the money. They have superb and potent engines that will allow you to use them at their maximum speed.
