BMW returned to V12 designs for its 7-Series sedan in model year 1986, forcing Mercedes-Benz to follow suit in 1991. While BMW sells far fewer V12-engined 7-Series vehicles than V8 versions, the V12 is marketed in the U.S., China , and Russia.[7] The BMW-designed V12 is used in Rolls-Royce cars, while the Mercedes engine was installed in Maybach cars.
