BMW Chassis Code & Model Year Guide

Easily find your BMW chassis code, model generation and production years in one simple reference chart.

BMW uses internal chassis codes (E, F and G series) to identify each generation of a model. These codes are much more accurate than just saying “3 Series” or “M3”, and they are critical when choosing aftermarket parts such as front lips, diffusers, side skirts, spoilers and bumpers.

This guide gives you an easy reference for common BMW chassis codes and the approximate model years they were produced. Use this page to confirm your chassis before ordering parts for your build.

What Is a BMW Chassis Code?

A BMW chassis code is an internal designation used by BMW to identify the platform and body style of each generation. Earlier models use E-codes (like E36, E46), newer models use F-codes (F30, F80) and the latest generations use G-codes (G20, G80, G87, etc.).

Even if two cars are both called “3 Series” or “M3”, they may have completely different chassis codes, body shapes and mounting points. That’s why all of our parts at JL Motoring are listed by the exact chassis code to help ensure proper fitment.

BMW Chassis Codes & Approximate Model Years

Below is a reference table for many popular BMW chassis codes, models and their approximate production years. Years may vary slightly by market and trim.

Note: Years listed above are approximate and may vary slightly by market and specific trim level. For a more exhaustive chassis list, you can also reference BMW-focused technical resources or specialist sites. Always confirm details by VIN or with your BMW dealer if in doubt.

Why Chassis Codes Matter When Ordering Parts

Many BMW models share a similar name (for example, “3 Series” or “M3”), but their body shape, bumper design and mounting points can be completely different from generation to generation. An E92 M3 front lip will not fit a F80 M3, and a G80 M3 diffuser will not fit an E46 M3.

When you shop for parts such as carbon fiber front lips, rear diffusers, side skirts, trunk spoilers and bumpers, always match the exact chassis code to your vehicle. This is how we organize our BMW catalog at JL Motoring to help ensure proper fitment the first time.
