MB 4Matic vs BMW xDrive vs Audi Quatro
Do we have a non bias comparison (or technical fact) between these two? I owned X5 before and they used more AWD propaganda than MB and Audi. I was invited couple time to their driving events to see the car in incline roller vs. lexus... to demonstrate the superior BMW xDrive system. But they did not put the MB because they said it will work too...
I love BMW Xdrive system and my current W212 4MAtic. In BMW, you can feel it when the system is working... it vibrates like hell... The MB just very smooth and probabaly a blink of Yellow triangle..
So, any thought, video clips, good review? Please make sure we compare to our latest generation 4Matic system.

My thought is maybe that you are referring to the traction control/ESP. In that, I do have experience with the BMW. Yes, it vibrates like hell. The Highlander and the WRX did not have traction control/ESP. I loved that! (Had the wife screaming when I did a 180 on a snowy road in the WRX when we discovered we turned right when we should've turned left.) I once thought the Carrera 4 was the gold standard for ESP until I met the MB ESP. Smoooth.... I know the Carrera 4 gave some "play" room, allowing some slippage as long as you are making good decisions. I think the MB ESP does too, which helps with smoothness.
The yellow triangle is connected to ESP, not AWD.
But maybe I'm missing something.
In BMW X5, I did sharp cornenring in sliperry condition. The whole car body vibrates and I felt like driving inside the rail. The cornering was some how precise but the independent automatic wheel braking was kinda scary.. I did tried the making sharp cornering in empty parking lot covered with snow with the new E. I could feel the self correcting but it is very smooth.
Now with the BMW Xdrive, I onced drove in complete black ice condition near Pensylvinia. All cars were stucked in icy highway, in the middle of road. Luckily, I was able to navigate slowly and keep it going. I then made a quick stop and could not believe how slippery the road condition was. No crazy noise.
Did the same thing with the E class 2-weeks ago. I did not know that the higway was closed due to icy condition. I had no issues at the ramp.

Honestly they all seem very comparable in winter traction and I never had an issue with any version in New England weather and ski trips. Any winter traction variables were probably more related to the types of tires versus the mechanical aspects.
In regards to driving dynamics and handling, I think I would give a slight edge to the Quattro. Audi develops their cars with Quattro as a central aspect of the cars ride and handling, while 4Matic and XDrive are options on basically rear wheel drive designed drivetrains.
Audis with Torsen centre differential fail to move when one axle has no grip (see rollers test on you tube)- this is one drawback with most previous generation Audis (4matic and xDrive pass this test). However, somethink like this is fairly unlikely to occur in road conditions.
As I said before, winter tyres are THE most important thing that will make your car safe to drive.
