A special X6 M prototype was spotted testing in Nurburgring. Not only will it produce more than a standard X6 M’s 555hp, it will also be lightweight — thus changing the overall feel of the driving experience. The special X6 M still sports a large hood air scoop, extractor outlets flanking the scoop, and more aggressive sideskirts. There are still no details of what powerplant this will be using.
