When driving on loose surfaces like gravel and snow, some slip (wheel spin) is necessary for the wheels to dig into the ground and find grip. As mentioned, a set of good winter tires will help significantly. |

If you're an experienced rally driver, then sure, activate DCT or even turn off DSC completely. Otherwise keep DCT off except for situation where you need to allow for more wheel spin. Driving on a snowy road at 40-50 mph is not one of these situations. If you however need to crawl up some slippery back road, then DCT can be of huge help, if not even a necessity.

That's how I drive (winter tyres), most of the time I've found you don't need to activate DTC, as spinning isn't the best way to move on snow anyway. Better to be very gentle on the controls and bite into the surface, before you make it more slippy with spinning wheels. I activate DTC when I need it and then switch back to full DSC. But most of the time just normal driving mode. HighlandPete |

I don't mean that you should be driving at the limit in public traffic, but using the Traction Mode will give you a bigger safety margin, since there is more grip available at the limit. Ice is a different matter, and requires less slip, unless you are running tires with long studs, or the ice is very rough. |

I'd not disagree with on the limits driving, but as I say, for most of my normal driving on snow, I've found you can just leave DTC off. I prefer to have DSC fully active if possible, as often in the UK we'll be on and off snow. For me, it is a case of balancing the risks when traction isn't the only issue. HighlandPete |

At these speeds and higher you will hardly ever experience that you don't have enough forwards momentum to get up a hill. Should this ever happen, then switching DTC on could help you. But leaving it on for all driving on snow, that is just begging for an accident to happen. Unless of course you've got mad skills. |

If you enter a corner a bit too fast in regular mode, the car is less likely to make it around than in traction mode, as the car will not allow enough slip angle to get maximum grip. BMW could just as well have named the traction mode "Snow" of "Gravel", as it has settings optimized for a loose surface. I think the traction mode is safer on snow than regular DSC even for rookies. Personally, I prefer the DSC completely off, but I don't recommend that to others. |

With the 116i, I can sustain a drift on snow and ice just fine, but I struggle to keep it going on tarmac. I use the throttle to control the angle, and sometimes I have to lift. When going back on the throttle, there is some turbo lag, and then I lose it. With more power it would probably work.

Ovekvam, I think the big difference is the majority of uk owners will be running wide low profile summer tyres and we have snow on top of ice.
So DTC will give more spin without forward travel just sliding about. As you will know with proper winter tyres DTC allows enough wheel spin to give added traction to accelerate forward. Summer tyres on snow just drive extremely slowly Winter tyres on snow its DTC all the time for me. Cheers Lee |

Depends on the traffix/where you are. Empty carpark? Turn DSC off. Normal traffic? Keep everything on. Empty wide roads? Depends on your skill, but turning only TC off will allow some driftangle but keeps it civilised.

It has to be said that recovering slides with the F20 is remarkably easy. The steering is quick, and the car is well balanced. Even without DSC or DTC enabled, it snaps back to going straight if the driver makes a correction. With the systems enabled, the car straightens itself unless you fight it. As long as you avoid actually spinning the tyres, the balance is pretty much unaffected by what you do with the throttle/brakes. Unlike many older BMWs, the F20 is controlled mainly by the steering also in slippery conditions, not the pedals. Aim the steering where you want the front of the car to go, and the car will do so. |

I've tried a bit wit our 116i, and it is rather amazing how easy it is to have controlled drifts/slides with this car and have the opportunity to exit the drift with just a correction on the steering wheel - totally undramatic. Especially with DTC enabled, you can have very much fun, and also get noticably more traction, without being afraid of doing 180deg spins. Even my girlfriend enjoys it with DTC enabled! She thinks it's very fun to drive under slippery conditions! |
