The concern produced the 1.6-liter turbo engine Mini Cooper JCW N18B16C from 2012 to 2017 and installed it on charged versions of the second generation Mini from Clubman R55 to Paceman R61. A motor quite similar in design was installed on Peugeot and Citroen under the EP6CDTX index.

Disadvantages of the Mini N18B16C engine
- First of all, this motor constantly overheats and cylinder head cracks are not uncommon here;
- A lot of problems are caused by the vagaries of the direct injection system with piezo injectors;
- Also, the Vanos phase regulators and the Valvetronic system very often fail here;
- There are many complaints about oil consumption and intake coking on specialized forums;
- A modest resource in this unit has a timing chain, thermostat and water pump.
