The upcoming BMW 335d has been spotted again being tested here in the U.S. This time the car was spotted sitting at a diesel pump somewhere in the southwest. The engine in the 335d, as well as the X5 diesel that is launching at the same time, is based on the existing dual turbo 3.0L in-line 6 used in several European models. For it's U.S. debut, the diesel 6 gets a urea injection system in addition to the existing diesel particulate filter. The new calibrations drop the power output from 286hp to 265hp but increase the torque from 413 to 425 lb-ft. The 335d will debut this fall along with a general mid-cycle refresh of the 3-series. That will bring some mild tweaks to the shape of the front fascia as well as the new iDrive interface that debuted this week on the new 7-series. For a preview of what to expect from the 335d, check out the ABG Garage review of the current European 535d
we did a few months back.
