2025 Audi RS 6 vs 2026 BMW X5 M

$126,600 · Wagon

$129,700 · Crossover

Comparison Overview

The 2025 Audi RS 6 unleashes brutal performance wrapped in an unassuming wagon silhouette, boasting 621 hp and 627 lb-ft of torque to dominate asphalt, while the 2026 BMW X5 M delivers supreme high-riding aggression in a practical crossover form. Although both command premium unleaded fuel and utilize AWD systems, their execution diverges sharply. The Audi, priced slightly lower at $126,600, offers a more engaging, lower stance (58.6 inches high) favoring agility, though its 14/21 MPG rating is thirstier than we’d like. Conversely, the X5 M starts at $129,700 with 617 hp and a slightly more commanding presence thanks to its 79.3-inch width. Crucially, the X5 M nudges ahead in utility, offering 33.9 cubic feet of cargo space compared to the RS 6's 30 cu ft, giving families a fractional edge, despite the RS 6's superior torque output.
