Here is the short answer on AWD vs 4WD in snow. The all wheel drive on a Dodge Durango or a Chrysler Pacifica works on its own, without being asked, which is what you want on a glazed stretch of highway at 100 km/h. The four wheel drive on a Ram or a Wrangler is a set of gears you choose, usually with a low range, which is what you want in a drifted grid road at a crawl. Neither one stops you any sooner. If the highway is where your winter happens, start with our new Dodge Durango inventory and see how an all wheel drive SUV fits your week.

We sell both kinds out of one store in Portage la Prairie, to Winnipeg minivan families and farm families near Austin alike. Our post on whether you need four wheel drive in Manitoba at all compares two driven wheels with four. This one compares the two ways of driving all four.

Key Takeaways

• All wheel drive manages itself. The Durango and the Pacifica AWD send power where it is needed, no switch to press.
• Four wheel drive is chosen. A part time Ram or Wrangler system is engaged by the driver and adds a low range.
• Some trucks and Jeeps blend the two. Ram's owner's manual describes a 4WD AUTO mode on some Ram 1500 builds, and Jeep lists full time Wrangler and Grand Cherokee systems.
• Pick by situation. Highway ice favours a system that works unasked; a drifted grid road favours low range and clearance.
• Neither system shortens a stop. Winter tires do that.

How the Two Systems Differ

Jeep Canada defines the two cleanly. A part time four wheel drive system "does not employ a centre differential and locks the front and rear driveshafts together." A full time system uses "a centre differential, which enables the front and rear driveshafts to turn at different speeds."

Locked driveshafts are strong and come with a low range, but they fight each other on dry pavement, because the front and rear axles travel different distances in a turn. A centre differential, or a clutch doing the same job, lets a vehicle stay in four wheel drive on bare and icy road alike. All wheel drive is that idea built for an SUV or a minivan, usually without a low range. Our guide to when to use 4 high vs 4 low covers driving a part time system.

What Each Vehicle Actually Has

These descriptions come from each manufacturer's own material. Trims and packages change the answer, so the window sticker is the final word.

Dodge Durango. Dodge Canada lists all wheel drive on its 2026 Durango trims, including the SXT and GT. Dodge describes the V6 system as hands free and full time, splitting power evenly between the axles, and the 5.7 litre HEMI V8 system as one that "continuously varies the torque split between the front and rear axles."

Chrysler Pacifica AWD. Chrysler's 2027 Pacifica release says its intelligent all wheel drive can send all of the available engine torque to the rear wheels or to the wheels with the most grip, and can disconnect completely when it is not needed. The release lists it on the Select, Limited and Pinnacle; confirm the Canadian trim on the sticker. Our Chrysler Pacifica AWD guide goes deeper, or browse the new Chrysler Pacifica lineup.

Ram 1500. Ram's owner's manual describes two electronic transfer cases for the 1500 4x4, depending on the build: a four position part time case and a five position case that adds 4WD AUTO, which sends power forward automatically when the truck senses a loss of traction. Browse the new Ram 1500 lineup and read the sticker.

Ram heavy duty. Ram's heavy duty 4x4 trucks use a transfer case with a low range. Whether a given truck adds an automatic mode is a question for its sticker and owner's manual, not a guess. Browse the new Ram 2500 heavy duty trucks.

Jeep Wrangler. Jeep Canada lists three systems. Command-Trac is part time: it "normally runs in 2WD mode," shifts into four wheel drive for slippery conditions, and has a 2.72:1 low range. Selec-Trac, as Jeep describes it, is an always on mode that switches between two and four wheel drive on its own. Rock-Trac, with a 4:1 low range, is listed as standard in part time form on the Rubicon, and Jeep's Canadian material lists a full time version as available on Rubicon models. Jeep Canada's page names the first two against some of the same trims, so below the Rubicon, the sticker settles it. See the new Jeep Wrangler inventory.

Jeep Grand Cherokee. Jeep Canada lists Quadra-Trac II and Quadra-Drive II as available. Jeep says the first uses a two speed transfer case with sensors that detect tire slip, and that it "works just as well in Canadian winters and deep snow as it does crawling up boulders." The second is full time and, as Jeep describes it, operates like traditional all wheel drive in Auto mode. See the new Jeep Grand Cherokee models.

Black Ice on the Trans-Canada Highway

Picture the run between Portage and Winnipeg on a November morning after freezing fog. The pavement looks wet and is not. You pull out to pass a grain truck, and the rear end steps a few centimetres sideways.

This is where a system that works without being asked earns its keep. A Durango or a Pacifica AWD is already sharing power between the axles when the patch arrives. A Ram with a part time case should be in two wheel drive on that road: Ram's owner's manual says the locked four wheel drive position (4WD LOCK or 4H, depending on the transfer case) is for loose, slippery surfaces only, and warns of tire wear and driveline damage on dry hard surfaced roads. A truck with 4WD AUTO, or a Wrangler with a full time system, narrows the gap, a fair reason to look for one on the sticker if you commute.

Know the limit. All wheel drive adds no grip. It shares the grip four tires already have, which helps you accelerate and hold a line under power, and does nothing for a corner taken too fast.

A Drifted Grid Road

Now the other end of a Manitoba winter: a grid road north of Highway 1 after a two day blow, drifts across the road to the hubs. Here the advantage flips. A part time Ram or Wrangler in 4 low multiplies the engine's pull at walking pace, and the clearance keeps the frame off the packed snow. A drift stops a vehicle by hanging it up, and no clutch pack fixes a high centre.

A Durango or a Pacifica will handle a plowed grid road and a light drift. A deep drift asks for clearance and low range those vehicles were not designed around. If your yard drifts in, that is the honest case for a truck or a Jeep.

A Rink Parking Lot

The slow one: a polished lot outside the rink in Portage after a Terriers game, everyone pulling out at once. All wheel drive simply works here. A part time truck can sit in 4H on a fully snow covered lot, but on tight turns across bare patches it can bind and hop; that is the locked driveshafts at work. Where a truck has 4WD AUTO, use it on a mixed lot. If a cold morning leaves the 4WD light flashing instead of engaging, our post on 4WD not engaging on a Ram or Jeep walks through why.

What Neither System Does: Stop You Sooner

Braking uses all four wheels on any vehicle, whichever system drives them, so neither all wheel drive nor four wheel drive stops you sooner on ice than two wheel drive on the same tires. The tire does that. Our comparison of all weather vs winter tires in Manitoba lays out the difference. We are a participating retailer in the MPI Winter Tire Program, and as of October 1, 2026, Manitoba Public Insurance says the program covers tires marketed solely as winter tires, so all weather and all season tires no longer qualify, even with the mountain snowflake mark.

Keeping Either System Healthy

Both kinds of system have parts and fluids that wear. Our service department does differential, transfer case and 4x4 service, so you can book a transfer case or differential service before the snow. Your owner's manual sets the intervals, and our post on differential and transfer case fluid service explains the work.

FAQs

Is AWD or 4WD better in snow?

It depends on the snow. All wheel drive is the easier tool on an icy highway because it works without being asked, and four wheel drive with a low range is the stronger tool in deep drifts at low speed.

Can I leave a Ram in 4WD on the highway all winter?

Only in 4WD AUTO, if your truck has it. Ram's owner's manual says the locked four wheel drive position (4WD LOCK or 4H, depending on the transfer case) is for loose, slippery surfaces only. The window sticker shows which transfer case your truck has.

Does the Dodge Durango have all wheel drive in Canada?

Yes. Dodge Canada's 2026 model pages list all wheel drive on the Durango, including the SXT and GT.

Which Jeep Wrangler has full time four wheel drive?

Jeep Canada describes Selec-Trac as an always on system, and Jeep's Canadian material lists a full time version of Rock-Trac as available on Rubicon models. Which system a given Wrangler carries is on its window sticker.

The Bottom Line

All wheel drive and four wheel drive solve different winter problems. If your winter is the highway between towns, a Durango or a Pacifica AWD handles the surprise patch for you. If your winter is a drifted road to the yard, a Ram or a Jeep with low range and clearance gets you home.
