$64,100 · Sedan

$52,600 · Coupe

Comparison Overview

Choosing between the 2026 Audi A6 and the 2026 BMW 4 Series often boils down to prioritizing prestige and space versus pure driving engagement and a lower entry price. If you need a comfortable daily driver that swallows highway miles gracefully, the Audi A6 is the clear frontrunner, boasting a robust 362 hp and 406 lb-ft of torque paired with standard all-wheel drive. However, the BMW 4 Series, priced $11,500 lower at $52,600, offers a tighter, sportier experience thanks to its rear-wheel-drive layout and slightly smaller footprint (187.9 inches long). While the Audi offers a larger exterior length of 196.8 inches, surprisingly, the BMW provides marginally more usable storage with 15.5 cu ft compared to the A6's 13.5 cu ft. Ultimately, performance seekers might overlook the 107 hp deficit in the BMW for its agility and better budget fit.
