It won't hurt the car if you change in motion. Benz recommend against it because the car could go into a skid or whatever in poor road conditions or it could startle the driver & cause an accident.

I went from C to S on the highway tonight traveling at about 70mph just to see what would happen if anything...seemed like it went from 7th gear to 6th as the engine gained about 200 more RPM... definitely felt it and watched it on the tach...

C/S will adjust TCU software settings and will "force" TCU to use lower gear at higher PRMs. TCU is smart enough to pick the right one and there is no way to break the system.

Yes, I've seen this mention in the W221 manual too (not sure if I was reading the Euro manual or a US pdf copy). The only reason I can think of why the manual states this is that the possible change of gear could make the car start a slide at extremely slippery conditions (absolutely theoretical case still).

the cool thing about S mode is that when u accelerate and slow down, it keeps your RPM around 3500-4000 so it gives you your full torque and almost all of your horsepower ready at any given moment so when you push the gas the car flies. The S mode also does stiffen up the suspension, trust me I feel it! braking is also improved in S mode because it downshifts quicker and keeps the car in higher rpms under braking so it uses more engine braking hp to slow down the car. S mode feels much better than regular, but it comes at a price(your MPG).
