Zitat von "bmwblog.com"On the diesel front things will be the same. The US might get only one diesel, in the guise of the 330d which will be powered by an upgraded B47 2-liter 4-cylinder engine with over 200 HP. On the global scale of things, the diesel range will go from the 316d model up to the M340d version that will be using a 3-liter biturbo engine good for around 320 HP and 650 Nm (480 lb-ft) of torque.
Es gibt durchaus "Quellen" die den 330d als 4-Zylinder beschreiben.
