2026 BMW 8 Series vs 2026 Genesis G90

$91,700 · Coupe

$92,700 · Sedan

Comparison Overview

The primary divergence between the 2026 BMW 8 Series and the 2026 Genesis G90 lies in fuel economy, where the G90 achieves a combined 21 MPG, notably better than the 8 Series (implied lower efficiency due to lack of rating, or standard RWD focus). Power output is another critical factor: the G90 delivers 375 hp and 391 lb-ft of torque, surpassing the 8 Series' 335 hp and 369 lb-ft of torque by a margin of 40 hp. Dimensionally, the G90 is substantially longer at 207.7 inches versus the 8 Series' 191.2 inches, translating to a larger footprint but slightly less dedicated cargo space (12 cu ft vs. 14.8 cu ft). Priced nearly identically at $91,700 (BMW) and $92,700 (Genesis), the decision pivots on the desired body style—a 53.0-inch high Coupe versus a 58.7-inch high Sedan—and the traction advantage of the G90's All-Wheel Drive compared to the 8 Series' Rear Wheel Drive.
