MINI Chassis Codes & Engine Codes

Every car manufacturer assigns an internal code designation to identify their vehicles. For BMW these are known as chassis codes and engine codes. These code systems help keep planning and development organized and avoids confusion. BMW engines for the MINI are known by W, N, or B codes. The chassis generation is distinguished by an “R” or “F” prefix (BMW chassis use similar E, F, G, or U codes).

All info below is based on US-market vehicles. This page is a work-in-progress and not set in stone.

As a BMW specialist we recognize the MINI as a BMW product but currently do not sell MINI parts. This page was built to complement our extensive BMW chassis and engine page.

MINI Engine Code Key:

BMW engines are classified with a 6 or 7-place alphanumeric code. Typically this is NOT found on the engine itself (or only a partial code is present). But you will see references to it in parts labels, diagrams, and catalogs. The simple code has a wealth of information - once you decipher it.

MINI Chassis & Engine Codes:

For MINIs the chassis code is also the body code. Since they are all "MINI Cooper" there is a need to differentiate one generation from the others. You won't find this code on your car anywhere (except maybe the Owner's Manual) but it is referenced on parts labels, diagrams, and catalogs. Knowing which generation MINI you have can be an enormous help in accessing parts and information.

 Happy Motoring!
