Comparison Overview

Deciding between the 2025 Audi A8 and the 2025 Genesis G90 often boils down to prioritizing established luxury cachet versus maximizing horsepower and saving upfront. Buyers wrestle with paying $92,000 for the Audi versus $89,700 for the Genesis. While the A8 offers a slight fuel economy edge, netting 22 combined MPG versus the G90's 21 combined MPG, the G90 punches harder with 375 hp and 391 lb-ft of torque compared to the A8's 335 hp and 369 lb-ft. Both AWD sedans are massive, with the A8 measuring 209.5 inches long. However, the G90’s slightly taller stature (58.7 inches vs 58.3 inches) might offer a negligible headroom advantage, though their cargo capacities are nearly identical at 12.5 cu ft (A8) and 12 cu ft (G90). Ultimately, the choice hinges on whether the A8's brand refinement justifies its higher entry price.
