4MATIC differentials
I was reading that the W204's 4MATIC system differs from the W203 4MATIC in that it is now an all-time AWD system as opposed to the W203 which is more of a 4WD system.
Does anyone here know what kind of differentials MB is using on the W204 4MATIC? Is it open in the front and rear with a mechanical limited slip in the center or are they all open? If they are using LSDs then what type are they using?
Thanks!

So it sounds like a multi-plate clutch center diff (not a real LSD, but acts enough like one) and then open diffs in the front and rear.
I wish that BMW and MB would follow Audi, Mitsubishi, and Subaru in using at least 2 LSDs (1 center and then another in the rear). Mitsubishi is actually use 3 LSDs these days in their Evo X (front, rear, and center).

I have not followed Audi but I would assume their latest implementations also making use of ABS brakes to emulate limited slip differentials. This comes for free and does not introduce additional weight or fuel consumption etc.
Subaru Evo cars are probably intended for pretty different use (I'm not familiar with those either) and then some real differentials make more sense.

Had an BMW X5 the other day. X-drive is a joke in corners: understeering like crazy and choking when you turn the wheel and floor it.

If you're going to make a claim like that then at least say what year the X5 was, what options it was equipped with, etc. We all know that BMWs and MBs vary greatly based on how they are equipped. I could say that 2003 MBs are slow and be referring to my C240 but obviously that doesn't hold true for a C32.

Look at pic is 1st link. It startss a and open biased center diff, and clutch plates are added, linking front and rear output shafts if lots of snow or ice are enountered.
And, don't forget the 7 speed locks up the TC in every gear, no slush box there.

The one you were driving likely wasn't a 4.8 and didn't have sport package. If you had hopped into one with the 4.8l. sport package, and the 20" wheels then you would have been having a lot more fun. Its actually incredible how well they handle.

Goes like stink in a straight line though, trashed a Z4 with it the other day. Hate it when people keep hanging right on my behind
Btw, with cornering I mean the ability to drift. More torques to the rear would be a good start.
