We need "Off-Road Assist" for snow driving

also disappointed to hear this. I got this car over others since it was AWD and I live in PA. I've driven RWD cars with winter tires here and it can be done, just a little pucker now and then. I thought this would eliminate the specter of getting my silly sports car stuck and calling the wife.....again. Any cars I've had that had trouble had aggressive or not easily defeated traction control. I am not aware that it can be disabled on this car. So track mode.....in snow.....is my option. Can't wait to try that /s
You can use slip start which I don’t believe turns the nannies completely off but it will let the wheels spin without chopping power.

Don’t be. I’ve had quite a few 4WD and AWD vehicles (Jeep, Audi, BMW, Toyota) - and my Model 3 AWS LR with stock tires has performed as well as any of them so far in the snow. I live in rural colorado so I’m driving on ice and snow and lately…had some deep snow. Drove through the snow-storm a week or so ago. It performed very well. And I know that Tesla does testing in Alaska for both 3 and Y. And Model 3s are extremely popular in Norway I believe.

Don’t get me wrong, though - I very much am advocating for a “snow mode” that takes into account regenerative braking, better power distribution, and more. I do think this is one of the biggest needs in an upcoming software update. Should’ve been done by now. Absolutely. However, I wouldn’t be disappointed.

That’s good news, Alex. To me, one of the benefits of having two independent motors (or better still, one at each corner) ought to be having the ability to have software work with the ABS sensors to control wheel slip appropriately for off-road or slippery roads. It would be disappointing if Tesla didn’t take advantage of it.

This conversation is interesting to me. I had to drive home in the midst of this last storm we had in my SR+ still equipped with the stock tires and had absolutely no issue other than visibility. I never once lost confidence in the car, I never lost control, and it handled itself like a champ.

My only complaint (which isn't really Tesla specific) was the wipers iced up and made the windshield worse so I had to stop on 95 a few times and try to get it all off.

I have had the complete opposite, driving with crossclimate+ in blizzards in Tahoe with no difficulties or slips whatsoever (except of course a few times in parking lots where I am purposefully drifting or pushing the car)

Honestly sounds like you all are trying to push it too hard and expecting the car to save you from poor driving. Never had any issues getting the car to do exactly what I want to do, even during a 5 foot blizzard

Sure having an off road option would be nice, all for more options, but dont expect it or another AWD car (like a Subaru) to save you from poor steering inputs in bad weather 20190225_205243.jpg 20190225_205235.jpg 20190303_085500.jpg 20190210_092638.jpg

Conditions differ. Snow can be really sticky, which likely improves traction. Or it can be powdery, which can be hard for finding traction. What's under the fresh snow matters.

I find it plausible that in a really slippery conditions going uphill a RWD-biased AWD system could struggle to get going. I've experienced it in one AWD Bimmer I've driven in the snow. FWD-biased AWDs like Audi, Subaru etc aren't a good comparison.

There's a similar discussion going on in the Model Y Forum right now - not clear that the off road assist is the magic answer as one person said it helped them, one didn't in that thread (still haven't had enough snow days to test it out myself yet). My first big snow drive experience in the Y dual motor was similar to Bjorn's description of the 3 below:

I suggest we all Tweet snow mode requests at Elon.

He sums up the issue perfectly in the video. I also learned something about how the 3/Y is different from S/X.

The guy who mentioned using Chill Mode nailed it. Not sure if any of you have tried that, but I had to venture out to rescue my wife on Thursday night, whose Audi autolocked her out with her keys in the car. Several road were closed, so I kept having to divert. And Knoxville is int he Smokey Mountains, I was on a lot of huge hills on sidestreets, and the snow was thick enough that I was pushing it with the car. Had my all season "range" tires on the car, fortunately. But I was absolutely blown away with how well the car handled the snow. The only care I've had that handled it better was an AWD car (Mazdaspeed6) I had that had snow tires all the way around. That was just becuase of the tires and where I lived (Ann Arbor, MI), which was flat with perfectly straight roads. I found the traction control to be exceedingly good - again, in Chill mode. Passed several stranded cars, and more than a few 4WD SUV's.

Yes have tried that it doesn’t solve the basic problem that the car is RWD until either it detects slip or you press hard enough on the accelerator that the system thinks that it needs to use the front motor to achieve the required performance.
The traction control is fine when you are moving. It also depends on the snow. Cold snow is grippy. Snow that is slushy, on top of ice, or otherwise wetter is much more slick. Next time it snows in Knoxville find a road with some incline come to a complete stop and try to go you’ll see that the rear wheels slip and then the front motor engages. You can demonstrate this in either standard/sport or chill modes.

Nothing works on ice. Nothing. And we don't get dry snow in Knoxville.

Ih, by the way......here is my driveway. What was that about stopping on a steep hill again?

I’m very glad the car met all of your expectations in snow that doesn’t change the fact that it is a RWD until it detects slip which doesn’t work a lot of the time. The snow the silver car is on is a good example of what we get when there is enough traffics volume to chew up the packed snow but not enough to get down to pavement like the left tire the red pickup is running on. This road is a 7%+ grade
