Mercedes-Benz Engine Codes: A Deeper Dive
While the model code gives a general idea of the engine, the engine code provides precise details. This code is usually found on the engine itself or in the vehicle’s documentation.
Understanding Engine Codes
Mercedes-Benz engine codes typically follow a format like “M276” or “OM651.” The “M” indicates a gasoline engine, while “OM” denotes a diesel engine. The numbers specify the engine family and series.
Common Engine Code Examples
Here are some common Mercedes-Benz engine codes and their corresponding engines:
- M274: 2.0L turbocharged inline-4 (used in C 300, E 300, etc.)
- M276: 3.0L turbocharged V6 (used in E 400, C 400, etc.)

Mercedes-Benz Optional Equipment Codes
Beyond the model and engine codes, Mercedes-Benz uses option codes to specify the equipment and features included in a particular vehicle. These codes are usually listed on the vehicle’s data card.
What are Option Codes?
Option codes are typically three-digit numbers that represent specific features or packages. For example, code “23P” might indicate the Driver Assistance Package, while “413” could represent the panoramic sunroof.
Finding Your Vehicle’s Data Card
The data card can usually be found in the vehicle’s maintenance booklet or obtained from a Mercedes-Benz dealer. It lists all the option codes applicable to your car.
Resources for Decoding Option Codes
Several online resources and Mercedes-Benz forums provide databases of option codes. These resources can help you decipher the meaning of each code on your vehicle’s data card.
Mercedes-Benz Model Code Evolution Over the Years
Mercedes-Benz model codes have evolved over the decades, reflecting changes in vehicle technology and design. Understanding this evolution can provide insights into older models.
Historical Model Code Systems
Older Mercedes-Benz models (pre-1990s) often used a different system. For example, the “W123” refers to a specific generation of the E-Class. These codes are known as “W” codes (for Wagen, meaning car).
Key “W” Code Examples
- W123: Mid-size car produced from 1976 to 1985 (predecessor to the E-Class)
- W124: Mid-size car produced from 1984 to 1997 (E-Class)
- W126: S-Class produced from 1979 to 1991
- W201: Compact car produced from 1982 to 1993 (190 series)
Modernization of Model Codes
In the 1990s, Mercedes-Benz transitioned to the alphanumeric system we use today. This change aimed to provide a more consistent and understandable way to identify vehicles.
