1997 E320 Traction in Snow
I had my snow tires mounted on a set of Mercedes knock-off rims (purchased from Bekers) so switching from winter tires to summer tires can be done at home.
I purchased my 98 E320 from San Diago, the previous owner put a set of Michelin Pilot XGT V4's on. When winter came in Chicago I could not make it from my driveway to my garage with 2" of snow and ice on my driveway. Since I put on snow tires, it's like driving on dry pavement.
There is also a difference between driving in 1" of snow and 5" of snow.
I put 150 lbs. over wheeel wells.
Any other ideas
Went thru some new Turnaza's ,little better but still hairy in the snow.Now its the Pirelli Snowsport 240's and they are smooth,even doing 130,recommended
I think all the major brands are worthy snows,to each his own.

The Best of Mercedes & AMG
I have Blizzaks mounted on the OEM wheels, and nice Touranza's on some nice AMG lower profile wheels for the Spring/Summer/Fall. Easy to just swap them when it's time.

Is everyone using their "W" position for the transmission?
That might help just a little?

Looks like a sneaky trick the MB engineers must have added?

There is some traction there at all times. Even under borderline conditions it is there,
but not as much as is there when conditions are perfect.
The idea is to be able to apply as little turning twisting force to the rear wheels as is necessary to get
you moving, but not so much as to cause a complete loss of any traction.
As you say, "a sneaky trick," but doesn't it work?
We have little need for it out here, but I do use it all the time to get a smoother take off from rest.
It did get me out of some deep mud just the other day.
As you know, the diesels do have maximum torque just off idle when compared to the gassers.
In years gone by, the engineers always had the automatics starting off from rest in second gear.
Perhaps this switchable feature is a carryover from those days?
The idea the engineers added to our cars was to force the transmission to start off from rest in a higher gear, in this case, second gear, to apply less torque to the rear wheels for better traction on slippery surfaces.
This feature also raises the gear ratio of reverse which is already considerably higher than first or second to begin with.
Mine doesn't like to start up from rest in reverse if I stop on my slightly inclined driveway while backing into my garage
should I forget to throw the switch back to "S" before engaging the lower reverse side.
Unlike the forward engagement, the transmission must be in neutral for the ratios to be changed.
To test this out while stopped on an uphill incline, release the foot brake, and your car will start creeping forward when in "S."
Throw the switch to "W" and it will usually stop creeping. Switching back to "S" and it'll start clawling forward again.
This demonstrates that there is indeed less torque multiplication in second gear than there is in first gear.
Clear as mud?
HTHs.
