According to a report in Car and Driver, the refreshed 2013 BMW 7 Series will be offered with diesel power here in the Untied States. The flagship BMW will be powered by the same 3.0-liter turbo-diesel inline-six that’s found elsewhere in the Roundel lineup, though as of this moment, it’s still unclear what sort of power or fuel economy figures are expected in the 7 Series. Expect the production model to wear either 735d or 740d nomenclature. Funk Flex
