This is the Mini Cooper SD, & it is the most powerful diesel ever slotted into the not-actually-that-small supermini.
The hatch, drop-top, Countryman & Clubman are now being offered with BMW's 2.0-litre four-pot oil burner producing 143bhp & 225lb ft of torque - more torques, incidentally, than any other Mini including the JCW editions.
