C-Class (S203/W203) 4MATIC thread - All you want to know
Overall, it was well worth the $1800 extra. Haven't been stranded yet, even with the performance tires, which are already wearing after only 7,000 miles. Ridiculous!!!
4Matic is full time all wheel drive, not 4 wheel drive. The ML's don't use 4Matic system, it uses 4ETS (Electronic Traction System) which is the full time 4 wheel drive.
Answer: 4.
Question: How many of those wheels are driven in a 4MATIC?
Answer: 4.
Question: So, all 4 wheels are driven?
Answer: Yes.
Look. This is really simple. 4 driven wheels = 4 wheel drive = all wheel drive in a 4 wheeled vehicle.
That is, the distinction between "4 wheel drive" and "all wheel drive" is meaningless in a car with only four wheels.
Oh, I know that the marketing guys apply the term AWD to vehicles with various types of 4WD systems (generally ones that are more sophisticated than your uncle's 1966 Chevy Pickup), but the use of the term "AWD" is rendered meaningless because it means something different to practically everyone who uses it.
Basically, you have an almost infinite number of variations on 4 wheel drive. Here are some examples:
- manually selectable 4WD, 2WD default (usually without a front/rear differential, so it can't be used on dry roads)
- 4WD with 100% front (or rear) default drive, varied by viscous coupling or similar electronic/hydraulic device, centre differential
- 4WD with default torque split other than 100% front or rear, centre differential, with or without limited slip differentials, with or without variable torque split according to electronic, viscous coupling or hydraulic means, via differentials or in the case of Mercedes, the brake calipers........
The only way to make an intelligent comment on this topic is to describe the technical caracteristics or relative sophistication of the drivetrain, which is what I tried to do in my earlier post.
Audi does use a Torsen center differential to split torque between front and rear while 4Matic brakes the wheels that are slipping (front or rear) to transfer torque through a non-torsen mechanical center differential. It is claimed that:
"Other systems use various forms of limited-slip differentials, but these systems can actually force one or more wheels to slip as torque is distributed, which is a disadvantage, especially on the hard surfaced roads."

I believe the STI uses limited slip differentials, but they are not Torsen.
All wheel drive provides two main benefits. The first is increased traction when starting from stop (without fishtailing), going uphill etc. The second is increased traction when coming out of a corner which allows you to use power earlier.
However, the added weight of the all wheel drive system means a little longer braking distances and all wheel drive does nothing for you in terms of ultimate cornering grip.
Still, here in New England I would not be without it and I love my Mercedes 240 4matic.

A little bit of wheel slippage is necessary for fast progress on a loose surface.
Watch a WRC Rally on Speed Channel and check out the starting techniques - it involves redline and full bore 4 wheel slippage for the ideal launch.
Once in motion, some drive wheel slippage on a loose surface is absolutely necessary to make rapid progress. If you've ever done some of this type of driving you'll know what I mean. The fastest way around a corner on gravel or compact snow is always in a 4 wheel drift, which 4MATIC, ESP, 4ETS, etc would disallow. Setting a car up for such a corner involves steering initially in the opposite direction of a turn , unbalancing the car with the throttle or brakes (requiring the ability to lock wheels under braking and spin them under power), then steering into the corner and rounding it in a 4 wheel powerslide using opposite lock when necessary. Great fun!
How many Mercedes owners would be tempted to try this I don't know (there must be a few - Mercedes track days are not unheard of), but it seems to me that people who are into this sort of action should (and do) stay away from 4MATIC because of its design conception.
The Best of Mercedes & AMG
Each car for it's intended use
I would use a C 4Matic for secure driving in foul weather, usualy on paved roads and not have to give up a "car" for an SUV on most days where it's not needed. I'd like the car to be stealthy in it's progress and still provide a comfortable secure ride all day long.
For spirited fun I have another type of vehicle all together in mind.
..jack

when its snowy here, I take it around in parking lots and just powerslide around, adding gas and steering it with control...lots of fun. No traction control or anything of the sort.
I have tried this with the ML as well, but 4ETS doesn't come into play when ESP is off...I have not tried it in a 4 matic car...hopefully soon so that i can compare the differences.
i live in Northern Jersey and i personnally drive my E320 in the snow without any problems at all. Now, there is a big difference with the 4matic system as the traction is better. But remember this my car was actually made with some steel and is hella heavier than the C class of yester year and especially the newer ones. so when i compared the 94 E to my 95 or 97 C i found the biggest factor was the weight of the vehicle. but in reality living in Northern NJ (vernon and above excluded) i would sack the 1800 dollar option and spend it on somthing else becuase the road plows do a fine job IMO.
I didn't do a camparison between the cars. Honesly, my main turn off was it was identical to a VW...I wasn't having that. I like unique cars...the S4 looks like every other Audi and VW. That being said, I also though the quality of the cabin was less then desirable.
I still don't see how VW can sell a car...the Audi adds $20K to the sticker and doesn't change too much inside, has identical body lines, and all of a sudden its a luxury car.

I See it this way.
Benz -------------- Luxury and Prestige
Bmw -------------- Luxury and Performance
Lexus--------------Luxury and Reliability
With audi, You are not getting Prestige or reliability. You get Luxury but Benz seems to be better here, You get performance but Bmw seems to better here
I don't really see where Audi fits in. They are nice cars but they do like way too much a VWs. I was looking at A4 3.0 when I bought my car. That said. Great Car, but probably would not buy one.
Sorry to get OFF topic
Carry on with the 4Matic
you are a good person and a good citizen for a couple of reasons:
1. you own a mercedes benz
2. you are intelligent enough to realize 4 wheel drive does not mean you need an SUV and for that we have one less SUV on the road! good decision.
Of course, even out of those, most of them think that AWD with snows is the best for winter weather.
Would people here agree with those sentiments?
This price is certainly very competitive and even lower than Audi of BMW.
thanks
h&r = 1.4" front , 1.3" rear
eibach = 1.2", 1.2"
i use h&r....my self
