$64,735 · SUV

$75,600 · Crossover

Comparison Overview

The 2025 Lexus GX explodes onto the scene as the torque titan, boasting a muscular 479 lb-ft of twist, perfect for conquering rugged terrain with its standard four-wheel drive, despite an efficiency penalty reflected in its 17 combined MPG. Conversely, the sleek 2026 Audi Q8 captivates with razor-sharp German design and superior efficiency, achieving 19 combined MPG from its less powerful 335 hp powertrain. While the Lexus stands significantly taller at 75.6 inches for impressive ground clearance, the Audi leverages its lower 67.0-inch height for a more dynamic stance, though it concedes substantially in low-end grunt compared to the GX’s 349 hp. With an MSRP difference of $10,865, buyers must weigh the GX’s sheer capability against the Q8’s broader cargo capacity of 33.7 cu ft versus the GX's 10.3 cu ft.
