We breakdown the latest tuning package from German tuners VÄTH, and their 680-horsepower SUV. Find out more inside.

German tuners VÄTH have introduced a new kit for the Mercedes-Benz G55 AMG.  The package includes a beefy power upgrade from the redesigned engine, as well as visual mods inside and outside the machine.

By changing out the intake manifold, adding new air outlets and a fuel cooler, the tuning team was able to get the engine just where they want it.  They retuned the engine to provide 680 PS (507 kW / 671 bhp), 840 Nm (619 ft-lb) of torque, and a top speed of 265 km/h (165 mph).

They proceded to drop the G-class by 35mm, adding sports shocks, and lightweight 10x22-inch wheels over 390mm brake discs.  Along with a new exhaust, the exterior now includes larger air intakes, Xenon and LED lighting.  Inside, new instrumentation can be seen behind the Alcantara steering wheel.  Leather was used throughout the cabin, with a new infotainment unit keeping the details organized.

Pricing has not yet been revealed for the VÄTH Mercedes-Benz G55 AMG.
