2025 BMW 8 Series vs 2025 Genesis G90

$91,700 · Coupe

$89,700 · Sedan

Comparison Overview

Deciding between stunning style and plush practicality often stumps luxury buyers, and the comparison between the 2025 BMW 8 Series Coupe and the 2025 Genesis G90 Sedan crystallizes this dilemma. While the G90 offers significantly more presence at 207.7 inches long compared to the BMW's 191.2 inches, it sacrifices some efficiency, clocking in at 21 MPG combined versus the 8 Series' 24 MPG combined. Interestingly, the Genesis leads on raw output with 375 hp and 391 lb-ft of torque, slightly eclipsing the BMW’s 335 hp and 369 lb-ft, despite having a slightly lower starting MSRP of $89,700 versus $91,700. However, the BMW's smaller 14.8 cu ft trunk barely edges out the G90's 12 cu ft. Ultimately, this choice pits dynamic coupe aesthetics against stately, AWD sedan comfort.
