2025 Audi S6 vs 2025 Genesis G80
Comparison Overview
Choosing between performance prestige and sticker shock is a common dilemma when looking at luxury mid-size sedans. The 2025 Audi S6 demands a significant premium, starting at $75,900 compared to the 2025 Genesis G80's $57,100, a difference of $18,800. However, the S6 brings substantial power to the table, boasting 444 hp and 442 lb-ft of torque, easily overshadowing the G80's 300 hp.

Ultimately, this comparison pits brute force and engineering cachet against exceptional mainstream value.
