BMW has confirmed that it will offer a diesel version of its new 5 Series luxury sedan in North America. What isn't clear is when BMW plans to launch the vehicle, or which diesel engine will be offered.
The decision would seem to be a clear cut one, with BMW currently using its twin-turbo 3.0-liter inline six engine in both the X5 xDrive35d and 335d, where in both cases it makes 265-hp and 425 ft-lbs of torque. It also gets an impressive 36-mpg highway on the 335d. BMW does offer a less-powerful sing-turbo 3.0-liter inline-six in Europe, which is unlikely.
But according to InsideLine, as the 5 Series diesel isn't slated to arrive for at least a few years and so several possibilities emerge. First, BMW could merge the two diesel sixes into one unit, with slightly more power and improved fuel economy than the current twin-turbo unit. There's also speculation of a diesel 4-cylinder. As unlikely as it is, BMW offers the new 5 Series as a 520d model in Europe, with an incredible 47-mpg highway rating.
In addition to the 5 Series, BMW will also launch another diesel model in the U.S. in the coming years, although BMW officials would not comment on what that would be. (We're thinking X1 or X3).
