2025 BMW ALPINA XB7 vs 2026 INFINITI QX80

$152,400 · Crossover

$83,750 · SUV

Comparison Overview

Deciding between outright performance luxury and premium practicality often boils down to budget, and this comparison hits that nerve hard. The 2025 BMW ALPINA XB7 starts at a hefty $152,400, nearly double the $83,750 MSRP of the 2026 INFINITI QX80, but justifies the gap with immense power: 631 hp versus the QX80's 450 hp. While their fuel economy is surprisingly similar (17 combined MPG for the BMW vs. 18 combined MPG for the INFINITI), the performance gap is evident in the torque figures, with the ALPINA delivering 590 lb-ft against the INFINITI's 516 lb-ft. If raw, high-speed capability is the goal, the ALPINA wins, but if you need a massive, comfortable cruiser, the QX80's larger physical footprint (211.2 inches long versus 203.9 inches) offers more presence, despite having significantly less cargo space at 22 cu ft compared to the ALPINA's 48.6 cu ft.
