BMW already offers an intelligent all-wheel drive system in the BMW X models as well as the BMW 5 Series and the BMW 3 Series, promoting both driving dynamics as well as driving stability and traction. With its special features, BMW xDrive has indeed already made BMW the world’s most successful manufacturer of all-wheel-drive cars in the premium segment. And now the range of cars with BMW xDrive is being enlarged once again.
Starting in the 2010 model year, BMW xDrive will be available for the first time also in the BMW 7 Series. In the BMW 750i xDrive and the BMW 750Li xDrive this permanent, electronically controlled all-wheel drive ensures appropriate distribution of the power of 300 kW/407 hp generated by the V8 with its BMW TwinPower Turbo Technology, thus catering for all demands in every situation.
Through a power divider with an electronically controlled multiple-plate clutch, xDrive feeds exactly the right amount of power in every situation to the axle which, through its wheels, has the best grip on the road. Precise and quick control of this power distribution gives BMW’s all-wheel-drive luxury saloons truly supreme and outstandingly safe driving behaviour under all conditions.
Through its dynamic operation, xDrive also helps to give the new luxury performance models with this technology the neutral behaviour in bends and supreme tracking stability so typical of an all-wheel-drive BMW. In bends more drive power is fed to the rear axle in order to make the car even more nimble and avoid any understeer.
In the process the operation of xDrive is based on the steering angle pre-determined by the driver. While, when driving smoothly in a straight line, the front-to-rear power split is 40:60, up to 80 per cent of the drive power goes to the rear axle in a bend, ensuring spontaneous steering behaviour precisely following the actual radius and course of the bend. Then, when leaving the bend, the distribution of drive power returns to normal in the interest of maximum traction when accelerating again in a straight line.

Does my 2006 325xi have the same xdrive system that was described? Or did they update the system in the 7er to give more rear drive bias in turns?
