$85,700 · Sedan

$117,750 · Sedan

Comparison Overview

The 2025 Audi S7 launches with the focused aggression of a performance grand tourer, boasting 444 hp and 442 lb-ft of torque packed into a nimble 196.0-inch frame, designed for spirited driving where handling reigns supreme. Conversely, the 2025 Mercedes-Benz S-Class enters the arena as the undisputed titan of luxury, prioritizing opulent spaciousness (208.2 inches long) and refinement, albeit at a significant $85,700 starting MSRP disparity compared to the S7's $85,700 entry. While the S7 delivers a punchier torque figure (442 lb-ft vs. 413 lb-ft), the larger S-Class manages marginally better efficiency with 24 combined MPG versus the S7’s 22. For those prioritizing outright driving engagement without paying the nearly $117,750 entry fee of the S-Class, the S7 is the focused precision instrument; however, if ultimate rear-seat luxury and size are non-negotiable, the flagship Mercedes commands attention, accepting its smaller 12.8 cu ft cargo hold for elevated prestige.
