Slipping & Sliding in Snow

[21st Century Pony]

We camped lat night in Colorado's Black Canyon of the Gunnison National Park. Temp was down to around 6 degrees in the late evening. Roads were snow-plowed but not down to the asphalt. Vredestein Wintrac Pro Winter tires gave a sure grip throughout.

Been driving around on ice for three days in Portland. Whisper, 1PD, Michelin ICE X tires. Zero issues up or down steep hills. It runs like a dream.

I'm running Nokian One tyres (yeah they are spelled like that) in Portland, I had to go up to Forrest Heights last night at midnight I was able to go up and down hills no problem. These tires are the best I've had on my mach-e.

Perfect. We are coming down this week for the dog shows at the expo. According to the weather looks like we maybe at the end of the snow/ice. Safe travels

I thought the factory tires (on the premium) ARE all-weather tires? ?

Nope, all season. All weather are new to the USA. The difference is extended traction in cold conditions and they have the winter tire rating. The Cross Climate 2 and Vredestein Quatrac Pro will also provide enhanced traction in wet and dry conditions.

I thought one pedal driving would be better in the snow. Isn’t it like downshifting in an ICE vehicle? I thought one pedal driving would be safer since it uses the motor rather than the friction brakes is that not correct?

It is similar to using the engine to slow down, but you don't have the equivalent of pushing in the clutch in an emergency to disengage the transmission completely. If you instinctively release the go pedal because you are sliding the regen kicks in full and thus makes it worse

All drive modes use regen - 1PD is just the most aggressive. As soon as you let off the Go pedal, the car will regen. Friction brakes only kick in at the very end, or in a panic stop situation.

Sort of: in 1PD the regen kicks in as soon as you let up on the go pedal (with the amount of regen determined by the amount the go pedal is released). With 1PD off when you release the go pedal the permanent magnets do add "friction" but regen doesn't really kick in until you start to hit the brake.

Ah....so if I'm in Unbridle and ease off the Go pedal and I begin to slow down (no brake pedal input), is that kinetic energy not returned to the battery?

FWIW I took my car into some slippery/snowy conditions this past weekend, and my Hankook Ion Evo tires that finally saw some snow handled very admirably. Other cars around me on this back road were spinning tires and sliding all over while I slowly and steadily passed them, until it got a little too sketchy, and I didn't bring my chains (stupidly) because I didn't think there would still be snow on the ground. Of course some of that might have just been the weight of the car, but I think the stock tires suck in rain/snow. I switched to 1PD Whisper when I hit the snow/ice.

Where I turned around:

Bonus: Of course had to stop at the brewery while I was up there.

Ok, what are the drawbacks to “all weather” tires versus “all season” tires? What you’ve said just sounds like “marketing-speak” (no offense intended).

Not really relevant, but why do they use British spelling in Portland? Canadian influence?

It's cool, all weather is technically a marketing term. That being said the tire manufacturers has agreed that the difference is all weather need to pass the three peak mountain snowflake certification test. Here in the USA is simply a acceleration test but if it's a tire certified in Europe it's breaking and acceleration. They are essentially what all season was intended to be. The best traction in all conditions.

What's the disadvantage? they are not as efficient.

Here is a video, I picked because the RAV4 has the same stock tire at the Mach E premium and Select. This test shows Bridgestone and I am not endorsing them just using it as an example.

I go from Unbridled to Whisper 1PD in the snow. Calms down the lift off on the accelerator pedal.

That's normally what I do, but today I wanted to toss the car around a bit in the snow and sleet. My tires are still original stock from April 2022 so I wanted to see if they still had any bite. Back end kicked out a few times but the car righted itself quickly. Starting on unplowed hills worked with only the slightest slip/pause.

I recently watched a traction test video on the Subaru Alterra (sp?). I was pretty impressed with the different traction/driving modes in that car. I know nothing about Ford's AWD know how or how much thought was put into the Mach-E but I was curious. I still put more faith in the rubber you choose than anything else but it seems like the AWD is working. I'd love to throw on a set of pure winters and rip around in a parking lot. ?

 

[Guss-E 2021]

so the traction control will let the rear end slide about 20 degrees before stopping it.

That's exactly what I experienced with my girl today. The first time made me a little nervous but once I knew what to expect, it became kind of fun. Nice thing about crappy driving weather around here: roads empty fast so a bit more room for error. I'm just glad Sheeba is home safe now in a warm garage and plugged in for the night.

Sorry but I just have to laugh. I was stuck in Portland this weekend for the big winter storm. All there was maybe an inch or two of snow and the whole city shut down! Back home now and we got 2 inches last night and 3 - 6 tonight and business as usual! I do recognize Portland does not see weather like that but restaurants and stores were shut down like it was the end of the world. Glad to know you could get around good in your Mach.

Because it’s a rare event, we are not as prepared, generally and don’t have as much equipment laying around. That and all the hills make it a mess when ice / snow hits.

With 1PD off, I believe that is correct - the kinetic energy is dispersed as friction with road, the permanent magnetic motor, and within the joints - as well as aerodynamic drag. Same thing when you put a stick shift in neutral and let it coast to a stop. If there is some low level of regen it is much weaker than when in 1PD, which is the operative point of this discussion.

All weather tires are not that good in snow and ice. There is another grade of tires called All Conditions with a mountain snd snowflake symbol. These can be used year-round as opposed to Winter tires which must be removed for the summer. Michelin X-Climate and Goodyear weather ready are 2 examples. We had 10’ on the ground last winter and they worked like chmps.
