BMW's E Chassis Code System

Throughout the Bavarian Soundwerks site, you'll find many product fitments designated with a 3 character code that starts with the letter E (i.e. "E36"). Below you'll find a key to let you figure out what model each code corresponds to.

Where did this code system come from?

With each new chassis made, BMW designates an E Code. The system is essentially BMW's internal system for classifying vehicles. Please note that the chassis codes DO NOT correspond to specific drivetrain or suspension configurations. For example, a '95 M3, 318, and 325 are all E36 models.
