BMW is in the midst of its final testing for the U.S.-spec 335d--the first diesel-powered Bimmer to be sold in North America. The introduction of the 335d will coincide with the launch of face-lifted sheetmetal destined for the entire 3-Series lineup.
Due to emission restrictions, the U.S. version of the 335d will reportedly be down on power from its European cousin (265 horsepower and 425 pound-feet of torque vs. 282 hp and 428 pound-feet), but even our U.S. numbers--especially the fat torque number--promise terrific performance that may well be enough convince people to make the move to diesel.
As with the 335i gasoline engine, BMW will use two turbochargers: a small, low-pressure turbo to aid low-end acceleration and a more potent turbo to help at higher engine speeds. Acceleration for the 335d is expected be around 6.2 seconds to 60, while fuel consumption will likely yield 23 mpg city and 33 mpg highway.
BMW's new diesel range is expected to launch under the banner: BMW Advance Diesel with BluePerformance (Blue denotes the use of AdBlue--the aqueous urea solution used to reduce the diesel's nitrogen oxide emissions). The 335d is expected to bow this fall.--KGP Photography
