Going on the dreaded Coquihalla in BC (Canada) and it's sometimes gets 70+ cm of snow overnight... we usually take the Sienna because of all the crap we take skiing, but now I have a roof box for the Pathfinder.

was thinking of either taking my 2017 Pathfinder SL 4WD or our 2014 AWD Sienna...

both have the same tires (defender LTX MS) with snow chains/cables.

both basically have the same clearance, but the Pathfinder has 4wd vs AWD on the van.

which do you think i should bring?

Hi there, after living in Lake Tahoe area for 25+ years I'd say Pathfinder would be my first pick.

Now, as I've owned a Sienna for the last 5 yrs, when it comes to room/space (fitting everything you need for a skiing vacation) I'd say the Sienna. With very good mud and snow tires, I've fround the awd system in the Sienna is quite good. I feel safe and in control with the right tires. The defender LTX MS tires with little wear should be perfect.

I've even pulled people out of snowbanks with my Sienna...

When it comes to all season tires most of them my miss the mark, when it comes to safety.

What I found with the AWD in the Sienna (in snow anyways) is that when the front tires spin, I hear an electric buzz, then the rears kick in. It happens on a sloped driveway covered in snow.

I thought AWD meant the rears had power at all times and not just when the front's have no traction?

I am not 100% sure about the 2014 Sienna, but these days a typical AWD powertrain is paced by the car's traction control system, which at any given moment decides where to send the engine torque and how much of it. In the Gen 4 e-AWD Sienna you can even watch the rear axle turn on- and off on the central display, which happens all the time in urban/suburban driving patterns.

Back to your question, I wouldn't dare to drive anywhere if there was a chance of getting 7 (much less 70+) cm of snow. Too scary.

Pathfinder and a 4WD system all day long......AWD is nothing but a crap system disguised to sell more and a marketing gimmick IMHO.....a 4WD system will make circles around an AWD all day long......just the fact that you can lock the differential and get all the juice out to all 4 wheels at all times and have the option of 4WD low gearing to get you out of the most difficult terrain is unparallel......stuff all ur gear in the rooftop box and enjoy the 4WD, in fact, you can also explore some trails 4 wheeling and go further......

Javvy, It looks as if you probably do a lot of off-roading, and that informs your ideas about AWD vs. 4WD, but I'd like to offer a different viewpoint, based upon my experience with both. We have lived in the western Nevada/Tahoe area for about 40 years, and regularly drove over the passes to the SF Bay Area to visit family. We struggled with 2WD vehicles and the hassle of chains until 1990, when we bought a used F-350 4WD truck. We really liked the 4WD in the snow, and when we went to cut wood, it was great for hauling us and our tools. It also meant that when we got to chain controls, we just sailed on through. However, 4WD was only comfortable off-road, or on snow/ice. If I forgot to take the transfer case out of 4WD when we were on dry pavement, we were reminded at the first sharp turn! Also, the truck had open differentials, so in very low traction, it would just spin one tire in the front, and one in the rear. In 1997, we bought a GMC Safari van with AWD, and a GM locking rear differential. That van has never gotten stuck, whether in snow, mud, or sand. If it had more suspension travel, it would be fun off-road van, even without a low-range. We still use it when we go up to the lake in the winter. In 2008, we bought an AWD Dodge Avenger. We drove to Portland on Christmas Eve that year in a very heavy snowstorm on many unplowed roads, and that AWD system worked like a champ. In Portland, the snow was about a foot deep on many side streets, and even with all-season tires, we were able to get around with very little trouble. That car was traded in recently on our 2015 Sienna AWD, and with the incredible amounts of snow we have gotten this year, the Sienna (again, with all-season tires) has performed without a hitch. Our final vehicle is a 2002 Suzuki XL-7 4WD that we tow behind our RV. It does well in snow/sand. but again, you have to constantly switch the transfer case as you transition from unplowed side streets to plowed, dry main streets. Because the Suzuki is a small car, and has decent clearance, we use it for our occasional off-road jaunts, and yes, the low range has been a help every so often. I don't think any of the AWD systems I've use have been "crap", they have all worked well, and we have traveled hundreds of thousands of miles with them with no problems.
Some told us that we would get worse fuel economy with AWD, and that may be true, but our Avenger regularly got 27-30 mpg on long trips, and our Sienna gets 25-27 mpg, so not bad at all.
Most of all, I like the fact that my wife will not have another disaster as she did when trying to drive our old Dodge van over the hill in winter, with 3 small children, and dealing with chains, then chains coming off, then chains getting wrapped around the axle, and having to hope someone would stop and help. AWD systems are great for what they are designed for. I realize this is a long post, but I wanted to offer a different perspective. YMMV!

Are you sure the Sienna has as much ground clearance as the Pathfinder? To me, that's the only possible argument in favor of the Pathfinder.
I don't think the 6.5-7 inches that the Sienna has will make all that much difference vs. a Pathfinder with perhaps 8-8.5", when you are plowing through a snowdrift :). The approach and departure angles might be more important, but what do I know :)

I am not sure if this is 100% correct in all driving conditions. I have zero experience with 4WD, but on all four vehicles with AWD that I have recently driven (CX9, CX3, CRV that were mechanical, and now the Sienna, which is e-AWD) the system performed very competently. I should say, I view AWD as a safety and convenience device - pretty much like I do any traction and brake control system.

4WD, as it is understood in the AWD vs 4WD context, sends all the torque to all the wheels all the time. It's a traction control system that is expanded to all the wheels instead of just 2.

AWD, in the same context, sends as much torque as needed, to those wheels where torque is needed, when it's needed.

I'm going Sienna.
1. The Sienna weighs more. not by a ton, but it counts for traction.
2 The Sienna has a longer wheelbase. This makes it easier to control at speed in nasty conditions.

I think the AWD system (at least on my 2020) is pretty good, especially for a 'Novice' driver in bad conditions. Having the ability to lock Diffs is great when you are stuck, but IMHO AWD is actually easier to control when you are moving. Not get me wrong, I had a Tundra, and symetrical 4WD in nasty stuff was tons of fun and driven well was about unstoppable, but that thing was even heavier and longer than the sienna.

I was coming over Berthouds pass in a snow storm this winter in my sisters 2004 4Runner on good tires and had my doors blown off by a AWD Sienna on winter rubber. It was impressive and I was reminded that for a vehicle with pretty good ground clearance the sienna had a much lower center of gravity in the turns.
