2025 INFINITI QX50 vs 2025 Mercedes-Benz GLA-Class
Comparison Overview
Deciding between the 2025 INFINITI QX50 and the 2025 Mercedes-Benz GLA-Class when both share the exact same $43,000 MSRP is a classic automotive head-scratcher. Do you prioritize on-road pep or better running costs? The QX50 brings noticeably more muscle, boasting 268 horsepower and 280 lb-ft of torque compared to the GLA-Class's 221 hp and 258 lb-ft. However, this performance comes at a fuel economy cost; the QX50 achieves only 25 combined MPG, lagging behind the GLA-Class's efficient 29 combined MPG. Furthermore, space matters, and the QX50 offers nearly double the usable storage with 31.4 cubic feet of cargo room versus the GLA's 15.4 cu ft. While both vehicles offer AWD capability in the specs provided, the GLA is notably smaller, measuring 173.6 inches long compared to the INFINITI's 184.7 inches, impacting maneuverability and interior volume significantly.
