The company assembled the 1.6-liter turbocharged Mini W11B16A engine from 2001 to 2008 and put it on charged versions of the Mini in the back of R52 and R53, such as Cooper S or John Cooper Works. This power unit developed its high power thanks to the Eaton M45 compressor.

Disadvantages of the Mini W11B16A engine
- The biggest problems here are associated with the not very reliable compressor Eaton M45;
- Also, owners of powerful versions of the Mini Cooper regularly complain about lubricant consumption;
- The reason for the unstable operation of the engine is usually a malfunction of the electric throttle;
- By a run of about 150,000 km, the timing chain often stretches and requires replacement;
- Another weak point is the fuel pump, hydraulic booster and expansion tank.
