According to the report, the white coats at BMW inserted a detuned 2.0-liter diesel that is longitudinally mounted in the 120d into the transverse engine bay of the MINI. The result was a MINI diesel with 40 hp more than the Cooper D, which currently uses an engine that BMW developed with PSA Peugeot/Citroen.
Autocar also reports that the twin turbo lump from the 123d can be fitted to the MINI, which could be used to create a diesel JCW. If they don't detune the engine, that would mean a 7 hp drop versus the gas-engined version, but 105 more lb-ft. of twist and better than 40 mpg when the drivetrain isn't being stomped on. Autocar says that BMW has begun testing the new diesels with an eye on retail sales in 12 months.
