300 Sport C or S? - Benzworld.org

I love my new C Class and noticed the transmission has a C and S function has anyone noticed a difference? When to use which? My dealer stated leave it in Comfort mode. Any ideas? Thanks

C stands for comfort mode, S stands for sports. It is a transmission configuration. Basically if you are in C mode, the transmission will start from the 2nd gear instead of first, and it will change gear at lower rpm. Whereas the S mode, you start from the 1st gear and it will rev up a little bit more before it changes gear.

Hope that helps

What is better? Is S used for certain situations like highway compared to local roads driving?

There's not really a "better". I prefer to use "C" as it makes the car take off more gently; used in "S", the 1st gear take-off is quicker but almost annoyingly so in traffic, plus you have a pretty quick gear change to 2nd. Try both for a while & decide which you prefer. I think it all got started as taking off in 2nd is ideal for slippery winter road condtions.

on some special occassions, i use S

i find very little difference. if i need more power ill just do that little power shifting thing..

You should get better gas mileage with C and more rapid acceleration and perhaps not so good mileage with S. Mine stays on S..all the time.

Depending on the milage, the manual may recommend using comfort for the first 1000 miles.

I know for a fact that the 2006 C 350 cited a break in period using comfort mode.

I also think there is very little difference.

I've changing from C to S mode all the time, even changing at alternating stop lights to compare them.... I think the difference is considerable, especially out of the hole and during spirited acceleration the S mode clearly delivers better performance. As already stated, the C mode starts from the 2nd gear and shifts earlier, delivering best fuel economy and smooth shifting. The difference in starting from 1st gear and from 2nd can not be under-estimated, and the later shifts allow the car to maximize the powerband through all gears, sucking up more gas. I also agree that during poor weather and road conditions, the C mode is probably a lot safer.
