After about a year, BMW will begin to offer a 3.0-liter diesel inline-six for its range-topping sedan, according to Caranddriver. Aside from a mid-cycle refresh for the 2013 7-series, there would also be another major update after a year. The output of this car has yet to be announced but this car will be named as either the 735d or 740d.
A 3.0-liter diesel is used on the X5 xDrive35d, enabling it to produce 265 hp and 425 lb-ft of torque. However, a high-output version of this engine available in Europe is capable of delivering 308 hp and 465 lb-ft. This means that BMW is the third German automaker to either confirm plans or offer a diesel flagship model in the U.S.
For now, Mercedes-Benz offers its six-cylinder S350 BlueTec in the U.S. Meanwhile, Audi’s A8 3.0 TDI will go on sale next year. Sources said that BMW intends to make the tri-turbo M550d diesel 5-series available in the U.S. To make this car, BMW bolted three turbochargers to a diesel inline-six-cylinder engine, resulting to 381 hp and 546 lb-ft of torque.
It’s not actually included in the list of products likely to arrive in the U.S. There are speculations that BMW AG wants to offer the market in Europe and the U.S. but it turns out that to justify emissions-compliance costs, the M550d would have to be on sale for more months than what remains in the life cycle for the current-gen 5-series.
