BMW has
confirmed that two diesel engines will be making their way to the US.
One is a
2.0L single-turbo twinscroll 4 cylinder direct injection diesel engine outputting
180 HP and 280 LB-FT torque, the same stats as the N47 engine which currently powers the F30 320d and F10 520d. As for consumption and performance, the 320d, for example, achieves an impressive 52.2 combined MPG (US) (40.5 city / 61.8 hwy), with a factory claimed 7.1 secs 0-60 mph.
The other diesel will be a
3.0L twinscroll 6 cylinder turbo outputting
255 HP (no official torque number yet, but expect 400+ lb-ft torque). This will be an all new engine not seen before in any other models.
These engines will be paired with 8 speed automatics and make use of SCR technology (urea based "selective catalyst reduction") to meet the stringent US diesel emission standards.
BMW has not yet confirmed which models will receive these engines, but they may see duty in a future 225d, 325d, 525d, 235d, 335d or 535d, as well as their counterparts in the xDrive models. The F30 3 Series lineup will likely be the first models to use the new engines.
