2025 GMC Yukon XL vs 2026 Lexus TX

$69,900 · SUV

$55,640 · Crossover

Comparison Overview

When choosing between sheer size and modern efficiency, the battle between the 2025 GMC Yukon XL and the 2026 Lexus TX really heats up. Buyers often struggle to balance massive capacity against running costs, and these two vehicles perfectly illustrate that trade-off. The Yukon XL, starting at $69,900, dwarfs the Lexus TX ($55,640) in size, boasting a lengthy 225.2 inches, which translates to a cavernous 41.5 cubic feet of cargo space—more than double the TX's 20.2 cu ft. However, this size comes at a cost: the GMC only achieves a combined 17 MPG, compared to the TX's impressive 23 MPG combined, saving owners significant money on fuel. Furthermore, the Yukon XL packs 355 hp and 383 lb-ft of torque for towing muscle, whereas the TX offers a more moderate 275 hp, though it curiously requires premium unleaded fuel.
