Mini has just unveiled details on the 2011 Cooper S that will go on sale on September 18, 2010, but we have just received new details on the hatchback just ahead of its sales date. German magazines report that Mini is planning to bring a diesel engine to the lineup.

Right now, the Cooper S comes with a new 1.6-liter four-cylinder engine and a new 2.0-liter, but starting next year, customers will also be able to get a diesel engine with their little pride and joy. The diesel engine that will be used is a BMW N47 based engine, with displacement change down to 1.6 L (from 2.0 L). The engine will develop a total of 143 HP and a peak torque of 300 NM. The same sources report that the new engine will also be used for the Countryman S.

It's true that this new engine will not be able to deliver the same output as the 1.6 Turbo engine, but it will still be a desired engine thanks to its autonomy. It is expected to have a fuel consumption of 4-4.5 liters per 100 kilometers and a CO2 emission of less than 110gr.

A similar engine is being used for both the BMW 1-Series->ke313 and the 3-Series->ke290.
