W124 4matic
Automatic all wheel drive. Normally rear wheel drive vehicle. Power is progressively transferred via multi-plate hydraulic transfer clutch to front wheels when slipping occurs. Torque distribution in this case is 65% to 35% rear to front. ABS sensors are used to detect wheelspin. If more traction is necessary, computer locks another clutch in rear axle. If brake pedal pressed, all clutches disengage to allow the ABS to work properly. On takeoff/acceleration the front axle normally engages, proactively, regardless whether wheel slip is detected or not.

W210 E-class
Full-time all wheel drive with 3 open differentials. Torque distribution 35% front / 65% rear via planetary gear. Electronic traction control applies brakes to the wheels that are about to spin and distributes torque from wheels that slip to the wheels with traction.

ML W163
Full-time all wheel drive with 3 open differentials. 4ETS electronic traction control, that applies brakes to wheel, that is about to spin, thus transferring torque to wheels, that have traction. M-Class 4ETS kicks in up to about 36 MPH (60 km/h) and if engagement conditions are maintained beyond 60 km/h during acceleration, control is effective to up to 48 MPH (80 km/h).
Two-speed AWD variant of the Borg-Warner 44-09 transfer case (2.64:1 low range).
The torque split is 50/50 up to October 19, 1998 when it was changed to 48/52 front rear.

There are 12 comments February 04, 2025 - 08:11Can someone please add the Viano/Vito’s AWD system?
Afaik it’s permanent & 35/65 F/R, with open diffs & just electronically braking the spinning wheels.
Was there a version with rear LSD too?
Rafn A Guðjónsson August 20, 2020 - 18:06Hi I need the diff lock for M.Benz 519 2019(new body) Can you help me?
November 27, 2016 - 06:31the GL X164 and the ML W164 w/offroad package have all wheel drive with 4ETS plus Center and Rear Diff Lock plus 2 speed transfer case
OliverTwist September 06, 2015 - 13:42Is there any reason why there's no 4Matic option for V12 motors in Mercedes-Benz S-Class?
Reply to OliverTwist November 27, 2016 - 06:27The Engine is so large, that they can't fit the front diff below it. Plus (and this part i'm guessing) all that power they probably haven't done a diff that can handle it in a small casing
June 19, 2012 - 06:43The C-Class W204 has the same system as the ML shown above, but without the 2-speed transfer case. Instead it employs a multi-disc limited slip diff integrated into the 7G-Tronic that is set bias 45:55. Bias could be varied 70:30 to 30:70. Other than that, the system is nearly identical: Front and Rear open diffs with 4ETS. This system is also employed on the GLK (non-off-road variant) and W212 E-Class. I believe the W218 CLS also shares the same underpinnings.
November 06, 2010 - 21:33Mercedes 4Matic has at least center multi-disc clutch LSD, which is not described here. It doesn't only rely on 4ETS to control slipery. This is very useful in low speed off-road condition.
Reply to Mega January 14, 2011 - 21:24The newest design 4matic has changed the center differential to a 45/55 split, and has an initial pre-load clutch. There isn't any variable clamp load to regulate the differential.
Mercedes probably could have achieved equivalent traction with the old transfer box by installing a torsen differential in the rear axle.
August 17, 2010 - 01:50That W124 transfer case is one of the most sophisticated, probably ever. You can have rear wheel drive [0/100, via a locked up center differential and open transfer clutch] Four wheel drive [35/65, via an open center differential lockup clutch, and closed transfer clutch] Rigid/fixed four wheel drive [both clutches closed, for getting yourself 'unstuck']
(if the electronics and rear transfer clutch were modernized, you could also have a variable distribution to the front)
Reply to George December 08, 2014 - 02:38do u mean 4matic ? 4matic fails here www.youtube.com
March 22, 2010 - 04:58If possible, please show some detail about the AWD system of S-E-C class that base on front wheel drive. Thanks
Reply to felix awdwiki.com June 10, 2010 - 00:55Never heard of a four wheel drive SEC-class.
