$43,800 · Crossover

$34,995 · Crossover

Comparison Overview

The 2026 Mercedes-Benz GLB immediately grabs attention with its premium aspirations, offering a zesty 221 hp and standard front-wheel drive for $43,800. This nimble crossover boasts superior acceleration potential over the rugged 2026 Subaru Outback, which grounds itself with standard Symmetrical All-Wheel Drive and 180 hp for significantly less cash at $34,995. While the GLB achieves a slightly better 28 MPG combined, the Outback dominates practicality with a cavernous 34.6 cu ft of cargo space compared to the GLB’s 22 cu ft. The powertrain difference is stark: the Benz requires premium fuel, while the Subaru runs happily on regular unleaded. For those craving European flair and responsive dynamics, the GLB beckons; however, the Outback’s substantial $8,805 savings and inherent capability present a compelling counterpoint for practical adventurers.
