btw, no new xdrive system either? I thought even the X3 is getting that. All it says is "xDrive, all-wheel-drive system with variable torque split" ...

An article for the current '07:
BMW's four-wheel traction solution is the latest version of its xDrive all-wheel drive system, which in the X5 typically provides a 40/60 front/rear split, but can send as much as 100 per cent of the available torque to either end of the vehicle.

Nothing new here.
