With the 2009 X6, BMW has created a new category that falls somewhere between crossover utility vehicle and sports coupe. The German automaker calls the four-seat, four-door-with-a-rear-hatch the "world's first Sports Activity Coupe" and the vehicle certainly is the only player in this new segment, at least for now. The X6 offers room for four adults and a long list of advanced technology that is highlighted by an all-wheel-drive system that not only transfers torque front to rear, but side to side and to individual wheels to produce the best acceleration. It's hard to pinpoint competitors for this segment-blurring vehicle, but they can include such players as the Porsche Cayenne, Infiniti FX50 and Jeep Grand Cherokee SRT8, not to mention the forthcoming Acura ZDX.
