2025 BMW X4 M vs 2025 INFINITI QX55
Comparison Overview
Deciding between high performance thrills and everyday sensibility is the big hurdle when comparing the 2025 BMW X4 M and the 2025 INFINITI QX55. The price tag immediately sets them apart; the BMW demands a hefty $79,100 MSRP, while the INFINITI starts at a much more accessible $50,150—a massive $28,950 difference. This financial gap reflects their core missions. The X4 M offers a staggering 473 hp and 457 lb-ft of torque, far eclipsing the QX55’s 268 hp. However, that power comes at a steep efficiency cost, with the BMW achieving only 17 combined MPG versus the QX55’s 25 combined MPG. While both are similar in size (BMW is slightly longer at 187.5 inches), the QX55 offers significantly more usable space with 26.9 cu ft of cargo capacity compared to the X4 M's 18.5 cu ft.
