Fresh off its mid-cycle update, the BMW 7 Series is once again the center of rumors, this time in the context of the new swath of M-branded vehicles that BMW is set to unleash upon the world. The rumor was dropped by German blog BimmerToday, and suggests that an M750i would join the ranks of the M550d, X5 M50d, and M135i. This seems rather plausible, as BMW has long been hesitant to produce an out-and-out M7 performance saloon. Funk Flex
