Mercedes-Benz Multipurpose Cabriolet (W31)

Six wheels, three axles, and a commanding presence — the G 4 Geländewagen was built to cross ground ordinary cars could not and to carry dignitaries who expected to arrive without compromise.

Mercedes-Benz engineered the W31 as a heavy-duty off-road and parade vehicle: dual rear axles sharing drive, a powerful eight-cylinder engine, and a high-riding chassis intended for military escort, state occasions, and rough-terrain duty. The six-wheel layout spread weight and traction where two driven axles at the rear could not.

Only 57 were completed on the W31 chassis between 1934 and 1939. Each G 4 was a specializt machine — scarce, imposing, and unmistakable — and the type established the Geländewagen name long before the post-war G-Class arrived.
