1939 Mercedes G4 #2409

The G4 was a development of the G1, launched in 1926. All had an 8-cylinder inline engine, in the first three years of 5018 cc (306.2 cu in) displacement delivering 100 PS (74 kW). It was a 6×4 configuration with four-speed transmission (synchronised upper gears) that transferred drive to all four rear wheels via self-locking differentials, the front wheels did not drive. The rear wheels were attached to two rigid axles 950 millimetres (37 in) apart, which were suspended in joint semi-elliptic leaf springs. The front axle was rigid with semi-elliptic springs. All six wheels had hydraulic brakes with servo assistance. The top speed was only 67 km/h (42 mph), limited by the type of all-terrain tyres. Only 11 of these vehicles were delivered to the Wehrmacht. The car used an elongated box-section frame that allowed for generous interior room. Comfortable seating for up to seven was provided by benches (front and rear) and one middle row of two with separate arm rests.

The vehicles were first delivered to the SS for use by Hitler and his adjutants painted with gloss gray bodies over gloss black fenders and running boards but, by the end of the war, they had all received anti-reflective matte and/or camouflage finishes in accordance with their military purpose. Many G4 vehicles belonging to the highest-ranking party members also featured rear-facing spotlights to be used to temporarily blind unauthorized drivers who followed too closely.

From 1937 a more powerful engine of 5252 cc (320.5 cu in) and 115 PS (85 kW) was used. The performance remained the same. Between 1937 and 1938 16 cars were built.

From 1938 a larger powerplant of 5401 cc (329.6 cu in) and 110 PS (81 kW) was used. Vehicles of this model were used by Adolf Hitler and his staff in parades marking the annexation of Austria and the Sudetenland. Thirty cars of this model were built, ending in 1939.
