Is the Solterra bigger than the Outback?

In short, no—the Outback is longer in overall exterior footprint. The Solterra, however, features a longer wheelbase, which can influence rear-seat legroom and ride quality. Here’s how the two Subaru models compare on the most relevant size metrics for recent years.


As of the 2024–2025 model years, official specs show subtle but meaningful differences between the two. While the Outback carries more length from end to end, the Solterra offers a longer wheelbase that can affect interior feel and ride dynamics. Exact figures can vary by trim and market, so for a precise comparison you should check the current brochure or Subaru’s official spec sheet for your region.


Size in numbers


This side-by-side looks at exterior footprint and cargo capacity to illustrate which model is larger where it counts for everyday use.



  • Exterior length: Outback is longer overall, by roughly 4 inches (Outback around 191 inches vs Solterra around 187–188 inches).

  • Wheelbase: Solterra has a longer wheelbase, by about 4 inches (Solterra ~112–113 inches vs Outback ~108 inches).

  • Width: Outback is generally wider (and easier to spot in traffic) by about 1–2 inches.

  • Cargo space behind the second row: Outback typically offers more, by a few cubic feet (roughly 32–33 cu ft vs Solterra around 30 cu ft).

  • Ground clearance: Both are in the same compact-SUV range, with similar values (roughly 8.3–8.7 inches), depending on trim.


In practical terms, the longer Outback footprint helps with cargo capacity and garage fit, while the Solterra’s longer wheelbase can contribute to rear-seat comfort and ride feel. The actual usable space varies by how you configure the seats and which trim you choose.


What this means for buyers


Choosing between the Solterra and the Outback comes down to priorities like cargo needs, parking practicality, and ride characteristics. Here are the key takeaways for shoppers weighing the two.


Practical space considerations


If you frequently haul a lot of gear or need easier daily parking in tight spaces, the Outback’s greater overall length can be a factor. If rear-seat legroom and ride refinement matter more, the Solterra’s longer wheelbase may offer a more comfortable experience on longer trips, even if the total footprint is smaller. Always compare the specific cargo figures and interior measurements for the trim you’re considering, since options can shift the practical result.


Summary


Bottom line: the Outback is bigger in overall exterior length, making it the larger vehicle by footprint. The Solterra, with its longer wheelbase, can deliver favorable interior dimensions and ride quality, but it does not surpass the Outback in total length or cargo capacity. For exact figures, consult the latest official specifications for your model year and region.

Is there a Subaru bigger than the Outback?


What is the difference between Outback and Ascent? At a quick glance, you'll observe that the Ascent looks like a big Outback...but there's a lot more going on beneath the sheet metal.

Does the Subaru Solterra qualify for the $7500 tax credit?


A press release says that the 2024 Subaru Solterra EV "will qualify for applicable federal tax credits of up to $7,500 for some owners." There's just one problem: the 2024 Solterra is built overseas and isn't eligible for the tax credit.
