The Mercedes-Benz G-Class AMG should be capable enough for highway driving based on its listed output. Key figures include 2025 AMG G 63: 585 Ps; 2025 AMG G 63: 430 kW; 2025 AMG G 63: 850 N·m. Power helps with maintaining speed, while torque matters when merging, climbing gradients or overtaking, so these figures are most useful when viewed through real Malaysian driving conditions.
