They look to be the same size but it's obviously less of an issue because they're not changing gears.

Here's pictures from a thread I found talking about the perfect travel mug because the cupholders suck. Notice the flat wireless charge pad in the back.

Got it. Man this situ is almost like being in Somalia with no food or water and surrounded by AK-47 wielding pirates. Much suffering, very 3rd world, wow.

I wish. I'm only at 378 miles.

We've gotten a bunch of snow this week including 4-6" today which means I've gotta drive it in the slush tomorrow to get my new tire.

I've also got questions for them about tire pressure as the door jamb says 32psi front and 33 rear for the OEM setup while the car is looking for something higher as it's telling me to inflate the tires despite them being at 34 psi. This leads me to the MyBMW app which is telling me it's 36psi front and 41psi rear.

32/33 seems very low to me but

Funny enough you mentioned that... the I4 was at 36/41 as well... and my IX is 36/42. There should be a "Tire" setting in the I drive.
When you set it to 100mph+ it may advise you to raise the pressure. See if that may be causing it... 32/33 seems low for bmw.

Also ... my IX is already at 700 miles...

I did the tire setting thing. Not sure if you can pick the tire size in other bmw's but I selected "winter" and picked the matching tire size for the rear axle so the car should know it has 275/35-19 all around. I did select 100mph+ since the conti's are rated for it. Seems weird that the 100mph option would put a consistent "inflate tire" message on the car.

Lower it and report back.

I rescheduled my appointment as some roads around me are still snow packed. Main roads are fine but getting to them might be an issue. Hell, I don’t know if I’d be able to get out of my neighborhood as my street and the main road in and out are still snow packed.

I forget what vehicle do you use when you can’t use the bmw ?

The Rage4. That actually handled the snow quite well the last few days.

I got stuck at Atlanta airport like 8-10 years ago due to a big snow, said fuck it I’m going home, rented a Rav and it was quite dece.

I thought you hated the Rav? I think they are alright. Comfy enough and look nice. And yeah these little crossovers with AWD do just fine in snow. My CRV was a champ in this last storm.

I was kind of surprised. I put it in snow mode and it did well. There's no hard button for diff lock but maybe that mode sends more power around instead of keeping it mainly fwd? It does have a torque vectoring rear diff though which was probably helpful.

The tacoma and other "truck" like vehicles have A-Trac... which is essentially brake based TC on each wheel. I would assume they deploy something similar on the other vehicles also.

Dynamic Torque Vectoring AWD With Driveline Disconnect
Solving some of those woes in other Toyota all-wheel-drive offerings is Dynamic Torque Vectoring AWD with Driveline Disconnect. This surprisingly sophisticated system is found in the RAV4 TRD Off-Road, Adventure, and Limited, as well as the Highlander Limited and Highlander Platinum. As on the more basic system, the all-wheel-drive transfer case is integrated into the transmission, but between it and the driveshaft is a dog clutch that can completely disengage when only front-wheel-drive is needed, reducing drag on the system.

A second dog clutch between the driveshaft and the rear differential further improves the system's flexibility in metering out power appropriately. What's more, clutch packs in the differential itself provide active torque vectoring—when one wheel loses traction and starts spinning, the clutches engage, sending power to the other wheel. By reducing its dependence on the brake-based traction control, the system is even better at keeping the vehicle moving forward.

It's not brake based on the limited Rage4 which is what we've got. The manual doesn't say what it does exactly but google tells me it dulls throttle input and cuts back on power.

that's a lot of clutches.

I had no idea they had different awd systems based on trim until the service guy started talking about transfer case and rear diff fluid changes

They probably put that same diff into the corolla GR
