Who Should Choose the Premium
The 2026 Subaru Outback Premium is the right pick for buyers who prioritize value and don't need every available feature. At $35,745, it delivers the core Outback experience — the same platform, the same 2.5L Flat-4 engine, and the same safety suite — without the cost of extras that many drivers rarely use.
If your driving is primarily commuting and errands, and you'd rather put the $4,250 price difference toward other expenses, the Premium makes a strong case. Budget-conscious buyers and those buying for reliability rather than luxury will feel well-served here.
Who Should Choose the Onyx XT
The 2026 Subaru Outback Onyx XT targets buyers willing to spend $4,250 more for a more complete package. That premium buys 78 more horsepower — features you'll interact with regularly, not just once at the dealership.
The Onyx XT appeals to buyers who want their suv to feel a step above the base experience. If resale value matters, higher trims also tend to hold their value better as a percentage of MSRP.

Why the Price Difference Exists
The $4,250 gap between the Premium and Onyx XT comes down to equipment and trim-level positioning. Specifically, the Onyx XT adds 78 more horsepower.
There is also a performance difference: the Outback Onyx XT produces 260 hp versus 182 hp, which translates to noticeable acceleration differences.
What Kind of Buyer Notices the Difference
Most technology-focused buyers won't find a dramatic difference between these trims — the core infotainment and safety tech carries across the lineup.
Casual drivers who use their suv primarily for commuting may find the trims feel very similar once underway. The differences are most apparent when you first get in, adjust settings, and interact with the cabin.
When Both Trims Feel the Same
On the highway at 65 mph, these two trims deliver an identical experience. Same engine note, same ride quality, same safety features active in the background. The Outback's fundamental driving character doesn't change between the Premium and Onyx XT.
Both trims also share the same warranty coverage, the same crash-test ratings, and access to the same dealer service network. If your priority is getting from A to B in a reliable, efficient suv, either trim accomplishes that equally well. The choice ultimately comes down to how much the in-cabin experience matters to your daily satisfaction with the vehicle.
