2025 GMC Yukon vs 2026 Chevrolet Suburban

$66,900 · SUV

$63,400 · SUV

Comparison Overview

The 2025 GMC Yukon roars onto the scene embodying premium, truck-based capability, while the 2026 Chevrolet Suburban counters with sheer, cavernous utility. Both heavyweights deliver identical power figures: 355 horsepower and 383 lb-ft of torque, feeding through a smooth 10-speed automatic transmission. Commuting fuel economy is also a dead heat at a combined 17 MPG. However, the Suburban stretches its dominance in pure hauling, boasting a massive 41.5 cu ft of cargo space compared to the Yukon's 25.5 cu ft behind the third row. The Yukon maintains a more compact footprint at 210.1 inches long, perhaps offering a slightly more manageable city drive than the Suburban's imposing 226.3-inch length. The $3,500 price gap, favoring the Suburban at $63,400 versus the Yukon's $66,900 MSRP, is the critical non-performance differentiator in this battle of full-size giants.
