This is a portion of the hardware on one of the wheels of the Mercedes-Benz G 63 AMG 6 × 6. Yes, no mere 4 x 4, this vehicle has six driven wheels, an off-road low-range ratio in the transfer case, portal axles (previously used in military vehicles), five differential locks, and a tire-pressure control system that permits adjusting the pressure of the 37-in. wheels to be adjusted while the vehicle is running. Based on the production G, this includes chassis modifications like specific springs per axle, as in springs for the front axle from an armored vehicle, springs for the first rear axle with a harder spring rate, and springs for the second rear axle with a softer rate. Oh, and there’s a 544-hp AMG V8 biturbo engine. According to Mercedes, this vehicle was essentially based on readily available G parts. Quite a shelf they have in Stuttgart.
