$50,150 · Crossover

Comparison Overview

Choosing between the 2025 Audi Q7 and the 2025 INFINITI QX55 boils down to balancing luxury presence against sharp value. If you prioritize maximum passenger/cargo space, the significantly longer 199.3-inch Audi Q7 offers a more traditional SUV profile, though it commands a hefty $10,350 premium over the QX55’s $50,150 starting price. Performance metrics are tightly contested: the QX55 boasts slightly more power with 268 hp compared to the Q7's 261 hp. Fuel economy is another key difference, as the QX55 achieves a better 25 MPG combined rating versus the Q7’s 22 MPG combined, despite both requiring premium fuel (the Audi requires it strictly, the Infiniti recommends it). Finally, the Q7’s tight 14.2 cu ft of cargo space contrasts sharply with the more practical 26.9 cu ft offered by the sportier QX55, making the upfront cost and running efficiency critical decision points.
