The 2025 Mercedes-Benz G 550 is the iconic luxury off-roader powered by a handcrafted 4.0-liter twin-turbo V8 producing 416 horsepower and 450 lb-ft of torque. Its body-on-frame construction, three locking differentials, and low-range transfer case provide genuine off-road capability, while the 9-speed automatic transmission and permanent AWD keep it composed on the highway. The boxy silhouette has remained largely unchanged since 1979, and the luxurious interior with Nappa leather and a 12.3-inch touchscreen proves that ruggedness and refinement can coexist.
