It looks like MINI will soon be launching a more powerful turbo diesel model to compliment the existing MINI One D and Cooper D. Our spies took these pictures showing the car with two centrally-mounted tailpipes, just like the Cooper S and the John Cooper Works. The Clubman version also sports one pipe on each side which on its own this information could throw off the amateur car sleuth.
What gave the game away was the distinctive engine sound that diesel-powered cars are known for. The front bumper is of a slightly different design as well. Some prototypes that have been spotted carried the cosmetic-only bonnet scoop, while others did not. Therefore we can't really say if it will be kept or not.
The petrol Cooper S range uses a 1.6-litre twin scroll turbo for maximum power output of 128kW (172hp) and 240Nm of torque (260Nm with overboost). The MINI One D on the other hand kicks out only 66kW (90hp) and 215Nm while its Cooper D brother works with 80kW (110hp) and 240Nm.
So expect the Cooper S D or whatever they end up calling it to make between 103kW (140hp) and 110kW (150hp) with peak torque hovering around the 300Nm mark.
