For most families making this drive, the Ascent is the right answer, and the sections below sort out when it fits, when it doesn't, and which Subaru suits your situation on the I-80 corridor.
The 2026 Subaru Ascent handles the Auburn-to-Truckee run better than any other model in the lineup for households of five or more. It seats up to eight, tows up to 5,000 pounds when properly equipped, and carries 8.7 inches of ground clearance with standard Subaru Symmetrical AWD on every single trim. What it gives up is fuel economy. The Forester and Outback both do the run more efficiently, and if your party is smaller, one of them is the smarter pick.
We rank them like this for the run. Passenger count and towing needs do most of the deciding.
How the Three Models Compare for This Drive
| Rank | Model | Best For | Passengers | Max Cargo (seats up/max) | Tow Capacity | AWD |
|---|---|---|---|---|---|---|
| 1 | Ascent | Groups of 5-8, gear haulers, trailer towers | Up to 8 | 17.8 / 75.6 cu ft | Up to 5,000 lb | Standard |
| 2 | Forester | Couples and small families, dog owners | Up to 5 | 27.5 / 69.1 cu ft | 1,500 lb (most trims) | Standard |
| 3 | Outback | Two adults, highway commuters, light cargo | Up to 5 | 32.5 / 75.7 cu ft | 3,500 lb | Standard |
All three come with standard Subaru Symmetrical AWD, and it earns its keep on this route. California's R1 chain controls on I-80 exempt AWD vehicles paired with snow tires, so when Caltrans puts up the restriction signs at Applegate or Kingvale, an equipped Subaru keeps moving where front-wheel-drive vehicles stop. None of these three require you to carry chains just to clear an R1 control, though you should always carry them for R2 and R3 conditions.
The Ascent: Built for the Full Cabin Crew
The Ascent earns the top spot for the full cabin crew because it swallows five people and their gear without forcing you to rethink how you pack. That same size, though, is exactly why it burns more fuel than the Forester or Outback when you run the drive light.
Load it with five people, four duffel bags, two dogs, and a ski rack, and you find the point where a smaller SUV starts to struggle. The Ascent takes it without rearranging your packing strategy.
Subaru's 2.4-liter turbocharged BOXER engine produces 260 horsepower and 277 pound-feet of torque. On the Donner Pass grade, where I-80 climbs to 7,056 feet, that torque number is what you feel. The Ascent pulls steadily under load instead of hunting through the CVT at altitude the way a smaller naturally aspirated engine does.
The cargo story comes with one catch. Behind the third row you get 17.8 cubic feet, which is generous for a three-row SUV but not enormous, so plan on room for a few soft bags. Fill the third row with people and your ski equipment goes on the roof or stays home.
The towing rating splits by trim, and it's worth knowing before you buy. The Base trim is rated to tow 2,000 pounds. Move up to Premium or above, add the optional Class III hitch, and the rating jumps to 5,000 pounds. A small ski boat or a loaded cargo trailer sits comfortably in that range. Planning to tow anything heavier than a bike rack? Trim selection matters more than you might expect.
Browse current Ascent trims in stock and confirm which trims have hitch-ready packages available on the lot.
The Forester: The Right Size for Smaller Parties
The Forester's the smarter Subaru for smaller parties on this run. Its lighter body and upright cabin make it easier to place on the mountain curves and easier to load, though its standard towing rating rules it out the moment your weekend involves a real trailer.
The 2026 Forester is a fully redesigned model, not a refresh. The structure is stiffer, the Dual X-Mode now splits into separate Snow/Dirt and Deep Snow/Mud settings, and ground clearance on the standard trims matches the Ascent at 8.7 inches. The Wilderness trim goes to 9.3 inches.
For two adults and a dog, or a family of three with reasonable gear, the Forester beats the Ascent for this drive. It's lighter, more nimble on the mountain curves past Emigrant Gap, and the upright cabin makes loading ski bags easier than the Ascent's wider, longer body. Cargo behind the rear seat runs 27.5 to 29.6 cubic feet depending on trim, so you keep real room even with the seats occupied.
See the 2026 Forester lineup if your crew tops out at four people.
The Forester's real limitation on this route is towing. Most trims are rated at 1,500 pounds, which covers a small utility trailer or a lightweight teardrop camper but not a full-size popup or a boat. If towing is part of your cabin weekend, target the Wilderness trim's 3,500-pound rating, which is built with an upgraded transmission cooler for exactly that load.
- Dual X-Mode with Snow/Dirt and Deep Snow/Mud settings (standard on Wilderness)
- 8.7-inch ground clearance on standard trims; 9.3 inches on Wilderness
- 180 hp from a naturally aspirated 2.5-liter BOXER engine
- No third row; rear seats fold flat for a long, flat load floor
- 1,500 lb towing on Base/Premium/Limited; 3,500 lb on Wilderness
When to Consider the Outback Instead
The Outback makes sense for a narrow slice of this drive, the two-person trip with a couple of bags and a preference for a low wagon load floor over an upright SUV seat, and it holds cargo like the Ascent with the seats down, though it can never seat a third row.
The Outback deserves a comparison here because it overlaps the Ascent for two-row buyers. The Outback's maximum cargo with the seats folded is comparable to the Ascent's. It's longer and lower, so it feels less imposing on the highway, and the XT trim's smaller turbo engine gives it genuine pull. Standard towing on non-XT trims is 2,700 pounds, and the XT trims rate to 3,500 pounds.
Compare current Outback configurations if you're deciding between these two.
What the Outback can't do is carry three rows of people, and that's the deciding factor. If your cabin trips ever need seating for more than five, the Outback closes that door completely. The Ascent keeps it open.
What Our Team Pays Attention to on This Route
We drive this corridor ourselves, so a few things stand out from the service and sales side that never show up on a spec sheet, from how AWD behaves under chain controls to how altitude and roof cargo quietly change what you get out of a tank. We're in Auburn.
- Symmetrical AWD isn't a marketing phrase on I-80. When chain controls go up at the R1 level, AWD vehicles with adequate snow tires keep moving, and all three of these Subarus qualify, which is a concrete, practical difference on a winter cabin run.
- The Ascent's 19.3-gallon tank and highway fuel economy let you run Auburn to Truckee and back without stopping. At altitude with a full load, expect real-world numbers a few mpg below the highway estimate.
- Donner Summit sits at 7,056 feet. Turbocharged engines like the Ascent's 2.4L and the Outback XT hold power at elevation better than naturally aspirated ones. The turbo compensates for thinner air. The Forester's 2.5-liter naturally aspirated engine handles the grade fine at normal loads, and you'll feel the difference only when you're close to max passengers and cargo.
- Roof cargo changes the aerodynamics at highway speed. Run a ski box on the Ascent and fuel economy drops.
The Bottom Line: Ascent for Groups, Forester for Smaller Parties
For Auburn families running five or more people up I-80, the 2026 Ascent is the cabin-trip vehicle. Its three rows, standard Symmetrical AWD, and 5,000-pound tow rating on properly equipped trims cover every realistic use case on the Donner Pass corridor, even though it asks more at the pump in return. It costs more and burns more fuel. For the right group size, the trade is worth it.
If your party is two to four, the Forester gives you the AWD confidence and mountain-road capability without the footprint. The Outback fills the gap for buyers who want the wagon feel and strong highway range in a two-row package.
