Although the engine's power is down slightly from its European version, which has an output of 286 horsepower and 428 lb-ft of torque, that model is not fitted with BMW's new emissions control system, which allows it to meet the U.S. regulations. Called BMW Advanced Diesel with BluePerformance (a much more complicated name for a system similar to Mercedes-Benz's BlueTec), the emissions control system consists of a standard oxidation catalyst housed in the same unit as a particulate filter, which has been placed right after the exhaust manifold and a selective catalytic reduction (SCR) catalyst with AdBlue urea injection designed to greatly reduce nitrous oxide and other diesel particulate emissions.
