$72,200 · SUV

Comparison Overview

Choosing between premium compact style and full-size utility often stumps buyers. If you are torn between the sleek 2025 INFINITI QX55, starting at an MSRP of $50,150, and the massive 2026 GMC Yukon XL, priced $22,050 higher at $72,200, the deciding factor often comes down to usage. The QX55 offers superior fuel economy, netting a combined 25 MPG compared to the Yukon XL's 17 MPG, which is a significant saving over time, especially considering the QX55 only requires premium fuel while the larger SUV takes regular. However, if sheer capability is necessary, the Yukon XL blasts ahead with 355 hp and 383 lb-ft of torque, significantly outgunning the QX55's 268 hp. The trade-off for the QX55's efficiency is a substantial reduction in space, as it only offers 26.9 cu ft of cargo compared to the XL's cavernous 41.5 cu ft, highlighting a massive gap in sheer volume for hauling gear.
