BMW has released some preliminary specs on the 2011 BMW 740i and 740Li which will be introduced at the 2010 North American International Auto Show next month in Detroit.  The 2011 740i and 740Li mark the return of a six-cylinder 7-series in America which has been missing from the 7-series lineup since the 3.4-liter inline-6 that was found in the 1992 735i.  The 740i will be powered by BMW’s twin-turbocharged inline-6 cylinder engine which produces 315-horsepower @ 5800 rpm and 330 lb-ft of torque available from 1600 rpm.  Power will be sent to the rear wheels by way of BMW’s 6-speed automatic transmission.   The 2011 7-series models will be available for purchase in Spring of 2010.
