$64,100 · Sedan

$50,600 · Sedan

Comparison Overview

Choosing between the 2026 Audi A6 and the 2026 BMW 4 Series Gran Coupe often comes down to balancing luxury aspiration against budget reality. The $13,500 gap in MSRP ($64,100 for the Audi vs. $50,600 for the BMW) is significant for many buyers. While the Audi A6 offers superior performance metrics—boasting 362 hp and 406 lb-ft of torque compared to the BMW's 255 hp—it asks for premium fuel usage without listing an MPG equivalent, whereas the BMW achieves a respectable 30 combined MPG. Furthermore, the A6 is physically larger at 196.8 inches long, contrasting with the BMW’s practical advantage of having 16.6 cu ft of cargo space versus the Audi's smaller 13.5 cu ft. This comparison hinges on whether outright power and size justify the higher initial investment and likely increased running costs.
