The Mercedes-AMG G63 is already a very powerful car, but the guys from G-Power disagree. This is why the 40-year old military off-roader is now available with some important performance kit. 

The German firm developed the Bri-Tronik 5 V1 ‘power module’. As a result, the V8 twin-turbo 5.5 liter engine can now deliver 645 horsepower (571 horsepower for the standard version) and 664 pound-feet of torque.

As a result, the Mercedes-AMG G63 modified by G-Power can now run from stand still to 100 km/h in just 5.3 seconds, while the special package also overrides the standard speed limiter. But stay still because the engine’s standard safety protocols remain in place.

On the exterior, the German off-roader has also received a new set of Hurricane RR wheels for the G-Wagen. The power module is priced at €5,796 ($6,465), the wheels at €8,391 ($9,360).
