$38,045 · Crossover

$45,800 · Crossover

Comparison Overview

Choosing between the 2025 Mazda CX-90 and the 2025 Mercedes-Benz GLB-Class boils down to prioritizing space and raw power versus efficiency and brand cachet, especially when facing the significant $7,755 MSRP gap. The CX-90 starts at a much lower $38,045 compared to the GLB-Class's $45,800, immediately favoring budget-conscious buyers. Performance is another stark contrast; the Mazda packs 280 hp and 332 lb-ft of torque, handily beating the Mercedes' 221 hp and 258 lb-ft. However, the smaller GLB-Class offers better fuel economy at 28 MPG combined, requiring the costlier premium fuel, whereas the CX-90 achieves 25 MPG on regular unleaded. Size matters too: the CX-90 measures 200.8 inches long, providing what is likely more interior volume, though the GLB-Class technically quotes a larger 22 cu ft of cargo space behind the second row, assuming a comparable seating configuration.
