Comparison Overview

The 2025 Porsche Cayenne embodies precision driving wrapped in a compact crossover shell, offering a sporty 348 hp channeled through its AWD system, despite its modest 19 MPG combined rating. Contrasting this is the imposing 2026 INFINITI QX80, a leviathan SUV that brings staggering 450 hp and massive 516 lb-ft of torque to the segment, albeit with a thirstier 18 MPG combined and larger dimensions at 211.2 inches long. While the QX80 boasts a significant 102 hp advantage and a lower entry price of $83,750 versus the Cayenne’s $84,700, the Porsche retains a crucial edge in efficiency. The Cayenne’s slightly better highway rating of 23 MPG outperforms the QX80's 20 MPG, making the smaller German contender more digestible for daily commutes despite the QX80’s greater sheer power output.
