If rumors are to be believed, the BMW 8 Series Coup is not long for this world. The good news, though, is that the impending demise is still a few years away. That should give us enough time to enjoy a model like the BMW M850i M Performance. Turns out, were not the only ones that have adopted a similar approach. Manhart Racing has been having some fun with the performance 8er, enough at least to create an arresting new tuning program that covers a lot of ground in the M850i. From exterior upgrades to engine enhancements, the German tuner has been a busy bee in the lab, though all that hard work appears to be time well-spent. This BMW M850i means business, and you wouldnt want to be in its crosshairs.
