Comparison Overview

Deciding between the nimble 2025 Audi Q3 and the roomier 2025 INFINITI QX50 often boils down to space versus badge prestige in the compact luxury segment. If minimizing upfront cost is paramount, the Q3 starts at $39,800, saving you $3,200 compared to the QX50's $43,000 entry price. However, that extra outlay for the QX50 buys significant capability, boasting 268 hp and 280 lb-ft of torque versus the Q3's 228 hp. While the Q3 offers better fuel economy with 23 combined MPG on regular fuel, the QX50 compensates with superior utility, providing 31.4 cu ft of cargo space—a massive upgrade from the Q3's 23.7 cu ft. Ultimately, the choice hinges on whether you prioritize slightly better city efficiency and a lower starting price (Q3) or significantly more power and cargo volume (QX50).
