In a recent interview in Munich, BMW has announced that the company's first major diesel coming to North American market will be a 3.0 liter inline 6 cylinders with variable twin-turbo technology.

BMW identifies that powertrain as the 3.0L twin turbo, a mill that accounts for 1% of 3-Series sedan sales and 7% of 3-Series coupe deliveries in Europe. Its greatest penetration is in the X3 cross/utility vehicle, with 8% of all vehicles fitted with the engine, BMW says. On the 5-Series, it appears in 5% of all sedans and 7% of all touring models sold in Europe.

There were previous rumors telling about a 535d coming in USA in 2009. Now BMW is offering for testings a 335d coupe, sedan and touring model; 535d sedan and touring model; and 635d coupe. And as BMW says the 335d and 535d would make the most sense in the U.S.

"Both of these models are absolute rockets, especially when accelerating from freeway speeds to Autobahn speeds."

The BMW 335d has a maximum power of 286 horsepower and a peak torque of 427 lb-ft of torque. It achieves a fuel-economy of 35mpg; that a 15 mpg difference compared to the current gasoline 335i on U.S. roads.
