BMW officially took the wraps off its first US market diesels since the mid-1980s today at the Detroit Auto Show. The 335d and exceedingly awkwardly named X5 xDrive35d are getting BMW's dual turbocharged 3.0L inline six diesel starting this fall. The 265-hp, 425-lb.ft. torque monster will make these vehicles among the most fuel-efficient and best performing vehicles in their class. They will also be among the cleanest being 50 state legal with particulate filters and a urea injection system that BMW is calling BluePerformance. So far no word on pricing, but based on the 535d that AutoblogGreen drove recently, this should be a killer combination at any price.
