2025 Mercedes-Benz GLS-Class vs 2026 Genesis GV80 Coupe
Comparison Overview
Choosing between ultra-luxury three-row comfort and a sportier premium package is tough. The 2025 Mercedes-Benz GLS-Class, starting at $89,200, offers sheer size, measuring 205.0 inches long, while the 2026 Genesis GV80 Coupe undercuts it significantly at $81,850. Although both boast 375 horsepower, the Genesis counters with an extra 22 lb-ft of torque (391 vs. 369 lb-ft) and a noticeable efficiency edge. The GLS achieves a combined 21 MPG, but the GV80 Coupe is more economical, especially since it only recommends premium fuel, unlike the GLS which requires it. Interestingly, despite its sleeker profile, the GV80 Coupe offers substantially more storage with 29.3 cu ft versus the GLS's tight 17.4 cu ft maximum cargo area. Ultimately, this decision pits established bulk against modern, value-driven performance and utility.
