The trick is in quicker response of xDrive system, other electronic systems (ABS, DSC, DCU, etc) are even more connected to xDrive operations, more factors / parameters included in xDrive operations, torque distribution also left/right not only front/rear - distributing torque dynamicly and separately to each wheel without torque loss, etc.

On-road test showed the new xDrive is much capable than the famous Audi's new rear-biased Quattro system.

Also: E70 will also be the first production vehicle to use FlexRay communication protocol (for communication between various control units in a vehicle) - allowing higher transfer rates & less errors. But the use of FlexRay will be limited in E70 - for dumper control only. New BMW F01/2 7-series will be the first car with full capacity FlexRay and many other revolutionary systems and solutions including heavily revised iDrive - this time having iPod for a role model.
