This fall, BMW will be introducing two new upgraded diesel engines to the recently launched 7-series in the 730d and 740d. Both engines have a 3.0-liter inline 6-cylinder layout with common rail injection and turbochargers. The 740d gets the 306 hp twin turbo engine we reported on earlier this week. The high end diesel gets the 740d to 62 mph in 6.3 seconds while scoring a combined 34.1 mpg (U.S.) on the EU drive cycle.
The single turbo version of the engine in the 730d also gets upgrades for 2010. With an output of 245 hp, the 730d does slightly better on the EU drive cycle at 34.6 mpg (U.S.) with CO2 emissions of 178 g/km. More importantly, it gets BMW’s BluePerformance package which adds a NOx trap to the diesel particulate filter. The NOx trap allows the 730d to meet the 2014 EU6 emissions standards.
While the EURO VI standard is significantly tighter it still allows about twice as much NOx as the U.S. Tier 2 Bin 5 standard, so we likely won’t be seeing either of these models in the U.S. anytime soon.
