the 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 September 06, 2015 - 10:42
Is there any reason why there's no 4Matic option for V12 motors in Mercedes-Benz S-Class? November 27, 2016 - 04:27
The 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 - 03:43
The 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. November 06, 2010 - 19:33
4Matic
Mercedes 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. January 14, 2011 - 19:24
Re: 4Matic
The newest design 4matic has changed the center differential to a 45/55 split, and has an initial pre-load clutch. Mercedes probably could have achieved equivalent traction with the old transfer box by installing a torsen differential in the rear axle. August 16, 2010 - 22:50
That W124 transfer case is one of the most sophisticated, probably ever. (if the electronics and rear transfer clutch were modernized, you could also have a variable distribution to the front) March 22, 2010 - 02:58
If possible, please show some detail about the AWD system of S-E-C class that base on front wheel drive. June 09, 2010 - 21:55
Never heard of a four wheel drive SEC-class. |
