$50,150 · Crossover

$62,000 · Crossover

Comparison Overview

Deciding between a stylish compact luxury crossover like the 2025 INFINITI QX55 and a more traditional, larger luxury SUV like the 2026 Audi Q7 presents a classic dilemma: flair versus functional size. The QX55 starts much lower at $50,150 compared to the Q7's $62,000 sticker price, saving buyers $11,850 upfront. Performance figures are surprisingly close; the QX55 boasts slightly more punch with 268 hp versus the Q7's 261 hp, though both recommend or require premium fuel. For fuel economy, the QX55 pulls ahead noticeably, achieving a combined 25 MPG versus the Q7's 22 MPG. However, the Q7's substantial size difference is clear in the back—it is over 13 inches longer overall, resulting in a significantly smaller 13.6 cu ft of standard cargo space compared to the QX55's 26.9 cu ft, likely due to the Q7's standard third row not being specified in the data.
