Who Should Choose the Outback Onyx XT
The 2026 Subaru Outback Onyx XT is the better fit for buyers who value what the Subaru Outback brings to the table. With 260 hp, it also delivers stronger performance.
Subaru's approach to this suv emphasizes a balance of features and value. If that aligns with your priorities, the Outback Onyx XT deserves serious consideration.
Why the Price Difference Exists
The $4,795 price gap reflects different brand strategies and equipment levels. The Outback Onyx XT carries a premium, which is driven by relatively modest equipment differences between the two.
Powertrain differences account for part of the gap — the Outback Onyx XT makes 73 more hp. Feature differences like a larger touchscreen, 73 more horsepower, larger wheels also contribute. Both are competitive within the suv market, and neither represents a poor value at their respective price points.
What Kind of Buyer Notices the Difference
Enthusiast drivers will feel the differences immediately if there's a powertrain gap. A 73 hp difference is noticeable during merging, passing, and hill climbs. Interior differences become apparent on longer trips where seat comfort, noise levels, and tech features matter more.
For buyers who primarily drive in urban and suburban settings under 40 mph, both of these suvs will feel remarkably similar in daily use. The differences surface on road trips, in extreme weather (where heated seats and AWD matter), and during technology-heavy interactions like navigation and phone integration.
When Both Suvs Feel the Same
In a parking lot, at a stoplight, or cruising in light traffic, these two vehicles deliver very similar experiences. Both are modern, safe suvs with contemporary safety suites, decent infotainment, and comfortable cabins. Neither will leave you feeling shortchanged in everyday scenarios.
The choice between Mazda and Subaru often comes down to brand loyalty, dealer experience, and which vehicle simply feels right during a test drive. We recommend driving both back-to-back on the same day — the subtle differences in steering feel, seat position, and visibility are more informative than any spec sheet.
