The letter “G” on certain manual gear sticks stands for Gelände, the German word for “terrain.” It is associated with the Mercedes-Benz Geländewagen, a vehicle originally designed for demanding off-road conditions.
Developed for military use in the late 1970s, the Geländewagen required a transmission capable of handling difficult terrain. Standard first gear was not always sufficient for the slow, controlled movement needed on steep or uneven surfaces.
The specialized G gear provides additional pulling power at very low speeds. It allows the vehicle to move through challenging environments without requiring excessive throttle or placing unnecessary strain on the drivetrain.
