For 2025 the C 400 X was brought up to Euro 5+ and given a much richer standard safety package, with ABS Pro, Dynamic Brake Control, Dynamic Traction Control and engine drag torque control. Styling was freshened with a new Rugged variant, storage grew slightly, the 6.5-inch TFT with connectivity became central to the cockpit, and options such as heated grips and seat, Keyless Ride and a 43.5-litre topcase were offered.
