2025 Mercedes-Benz G-Class vs 2026 Genesis GV80 Coupe

$148,250 · SUV

$81,850 · Crossover

Comparison Overview

The 2025 Mercedes-Benz G-Class erupts with raw, boxy, go-anywhere capability, boasting 443 hp and legendary off-road prowess, commanding a steep MSRP of $148,250. Contrast this with the sleek, dynamic 2026 Genesis GV80 Coupe, a style-focused crossover offering 375 hp for a fraction of the cost at $81,850. The G-Class dominates raw muscle, delivering significantly more power and a more commanding road presence with its 77.7-inch height. However, this prestige comes at a heavy price: the G-Class achieves only 18 combined MPG, whereas the more nimble GV80 Coupe (195.5 inches long) offers vastly superior efficiency for daily driving. The massive $66,400 price gap makes the GV80 Coupe an astonishing value proposition against the opulent, but less efficient, three-pointed star SUV.
