BMW has the BMW Concept X6 on show at the 2007 Frankfurt Motor Show, but we all know that the concept bit in its name can be pretty much dropped as the car is very close to production, with nearly undisguised mules spotted on the roads just right before the motor show began.

BMW calls the Concept X6 a Sports Activity Coupe, or SAC if you like. The coupe-like roofline dropped immediately right after the position of the steering wheel inside the car. The four-door coupe form is combined with the commanding driving position of a 4X4 vehicle. All of the classic BMW design cues are there – double kidney grilles, double headlamps with corona rings, Hofmeister kink.

With this Concept X6 also debuts a new technology from BMW called Dynamic Performance Control. Dynamic Performance Control works hand in hand with the xDrive four-wheel drive system to spread drive torque as required in all situations. Think of it as DSC stability control without cutting off power or braking, instead purely achieving control in understeer or oversteer conditions by varying power between the two wheels at the rear. While DSC applies power to the inner wheels when the car is oversteering, DPC achieves this by shifting more power to the outer wheels.

If you think about it, Dynamic Performance Control is most likely BMW’s own branding slapped onto GKN Driveline’s Vector-Drive torque-vectoring rear axle that was announced sometime towards the end of July 2007.
