However in the G20 3-Series, earlier press releases made note of it being a fully disconnecting AWD system. During acceleration, it’s AWD with a rear bias but during regular cruising speeds it switches to pure RWD mode.
Wards has an interesting article on the new Magna FLEX4 disconnect unit. And IIRC, the G20 was the first BMW to get this new version of xDrive.

I don't think this is entirely accurate. Yes, xDrive in the G generation is improved, but it is not a "fully disconnecting AWD" system as you said - except in M Competition vehicles. For all others including G2x vehicles, it is always connected, rear biased, and can send 100% of torque to rear wheels. Only M Competition vehicles get fully disconnecting xDrive.
