Confirmed: BMW Bringing Turbo-Diesel I-4, I-6 Engines to US Market

After the recent death of the 335d sedan, it looked as if BMW’s diesel efforts in the U.S. were relegated to the X5 model line. Not so fast: BMW confirmed today that it will bring a four- and six-cylinder diesel engines to the U.S. market within the next twelve months, and there’s more than a strong chance it could appear in the likes of the 3 Series range once again..

Automobile senior editor Jason Cammisa announced on Twitter early this morning that BMW will bring a 2.0-liter, single-turbo, inline-four-cylinder diesel engine. He added that the engine should make 180 hp and 280 lb-ft of torque. Those specs should sound familiar, because they are: the U.S.-spec engine has an identical output to the 2.0-liter I-4 turbodiesel under the hood of the European-spec BMW 320d sedan and wagon.

BMW also confirmed a twin-turbocharged, 3.0-liter diesel I-6 will be added to its U.S. powertrain portfolio within the same timeframe. Though it sounds similar to the engine presently offered in the X5 xDrive35d and in the old 335d model, it’s an all-new engine, and from the same family as the engine used in the European 330d Touring model. U.S.-market specifications are still being ironed out, but it’s expected to produce close to 255 hp, and a stout 413 lb-ft of torque between 1500-3000 rpm. We hope (and think) this engine is destined for a U.S.-market 3 Series, as it’s capable of pushing the 330d Touring from 0-62 mph in a respectable 5.6 seconds.

BMW says both engines will be paired with eight-speed automatic transmissions, and utilize a urea-based selective catalyst reduction (SCR) system to meet emissions standards. What it hasn’t said, exactly, is what model lines receive what engine, and when. The diesel I-4 is offered abroad in the 1, 3 and 5-Series ranges, along with both the X1 and X3 crossovers. The I-6 is a shoe-in for the large X5, but it could also appear in either the 3- or 5 Series model lines. Another possibility for the I-6: the 7 Series, as Mercedes-Benz recently began selling its diesel-powered S350 Bluetec in North America.
