BMW has just announced an upgraded version of its 3.0-liter inline six-cylinder diesel engine. The new version retains the same displacement, yet output for the European spec version is increased from 286 horsepower and 428 lb-ft of torque to 306 hp and 442 lb-ft. At the same time, fuel consumption and CO2 emissions are reduced by four percent compared to the previous version.

BMW has updated the fuel injection system to its latest generation common rail system. That means the injector pressure has been bumped from 1,600 BAR (23,000 psi) to 2,000 BAR (29,000 psi), allowing for even more precise metering of the fuel flow. The dual stage turbocharger system is now also more efficient. Since BMW only just introduced a version of the previous engine with U.S. legal after-treatment systems in late 2008, it seems unlikely that the U.S. will receive the upgrades in the near future.
