BMW’s latest green-car gambit arrives at the Detroit auto show in two weeks, as the German automaker plans to show off two new diesels that it will sell in all 50 states starting later this year.
The two new models are the X5 xDrive35d and the 335d. Both are powered by
twin-turbo, 3.0-liter in-line six diesels that use a urea-aftertreatment SCR
system similar in concept to that in Mercedes’ Bluetec diesels. With the SCR
setup, BMW’s diesels meet the tough new U.S. diesel regulations introduced last
year.
In both applications the new diesel engine will produce 265
horsepower and 425 pound-feet of torque. Variable twin turbos and the low-end
strength of diesels mean the new six-cylinder makes its torque peak at a low
1750 rpm. With direct injection as well, the engine consumes 25 percent less
fuel than a similarly sized gasoline engine.
In the 335d, BMW says this
kind of power will enable a 0-60 mph time of 6.2 seconds and fuel economy of
23/33 mpg. The X5 fares almost as well, accelerating to 60 mph in about 7.2
seconds and delivering fuel economy of 19/25 mpg. (Fuel economy figures are
preliminary, BMW cautions, as the vehicles won’t be on sale until the end of the
year.)
Stay tuned for more information on the diesels, and on all the
other Detroit debutantes, as TheCarConnection.com covers the auto show starting
January 13.
