Snow Mode fail - costly result

[NY_Rob]

More likely the regen helped break the coefficient of friction.

When I was a kid, my first few vehicles were manual tranny pickup trucks. I quickly found out that depressing the clutch around sharp turns (when turning off on to a side street for example) was the best way to prevent rear end kick-out when driving in snow. That was the equivalent of turning off regen in a modern vehicle.

Like putting it in neutral

I wonder how many folks have the reflexes to pop their Rivian in neutral as quickly as they can release the accelerator. Actually shifting the Rivian to neutral requires looking down, at least for me, it is a bit finicky.

It does do a proper neutral but there's a delay that is substantial. You would have to anticipate needing neutral. I can see where approaching a steep rutted or slippery spot that you could hit neutral in time but not in an emergency like with a clutch or automatic tranny. I guess a PDK or DCT doesn't have neutral availble either.

Exactly. Anticipation is the key to good driving.

Traction helps too

I was thinking about the feathering approach, too. Especially if there isn’t an “off” option for regen. I’m pretty good doing controlled “power slides” from years of ripping around on ATVs and driving 4x4s in the back 40 where I grew up. I think I could try that next time if that’s the only option. I just don’t see my wife doing that and I’ve been urging her to drive the R1S in poor conditions because it’s “the safest option” for handling bad roads. Now I’m not too sure I want her dealing with this type of scenario…

I learned the first slippery day we had, leaving my driveway.... Gotta just lightly accelerate, seriously, one time, and I got it.... It just drives differently on slippery roads, and you adapt.....

What tires?

For Ice and Snow it’s 95% tires.

I leave full regen on since 2019 on 3 Teslas and never came close to an issue because I always run top notch snow tires. And don’t go out if it’s stupid bad out. Because some dope will slide into you even if you don’t.

I don’t run studs because of their danger once the roads do clear.

And if regen mode makes or breaks you then you are on the hairy edge of crap for traction.

I suspect it was the Pirelli. They suck in the snow

I have had a similar experience to OP in snow. I'm using Nokian Outpost nAT tires. The uphill traction is really good so I don't get stuck, but for some reason the downhill traction while braking is much worse. I'm not sure if it's from the regen locking up some wheels while going downhill, but the truck can be scary to drive going downhill in the snow.

7000 lbs...downhill. Might be better with snow socks or winter tires but 7000 lbs ..
