BMW series engine numbers are located on the engine block, at the connection point between the cylinder head front end and the engine block. BMW engine models consist of six digits, with the first three digits typically used as follows: 1. The first digit is an English letter, such as B, M, N, or S, which can be considered as the engine series; 2. The second digit is an Arabic numeral, commonly 4, 5, 6, or 7, representing the number of cylinders in the engine; 3. The third digit is also an Arabic numeral, indicating the configuration level of engines within the same series and type, which can be viewed as the engine's advancement level—the higher the number, the more advanced the engine. BMW cars refer to vehicles produced by BMW AG, with main series models including 1, 2, 3, 4, 5, 6, 7, and 8.
