Mercedes-Benz G4: The Six-Wheeler Hitler Handed Franco

Three axles, six wheels, and drive going only to the back. The front axle of the Mercedes-Benz G4 steered the car but drove nothing: it got no power at all. It was sold as the off-roader of the Nazi high command, and when Franco took it hunting outside Madrid it buried itself and had to be towed. That is the machine now sitting in the royal coach houses at El Pardo, valued at around 25 million euros. Here are the facts, the numbers almost nobody gets right, and why Mercedes itself restored it for free and certified it as the best-preserved example on Earth.

Three axles, rear-wheel drive

It arrived in 1934 under the internal code W31, a descendant of the 1926 G1 (the W103, of which only seven prototypes were built and then destroyed), Daimler-Benz’s first stab at a six-wheeled cross-country car. On paper it was imposing: three axles, six wheels, a straight-eight, more than three and a half tons. The rear compartment even had room to mount MG-34 machine guns, because the Wehrmacht had commissioned it as a command car.

That is where the lie starts. As a weapon it was useless. The layout was 6×4: drive went to the two rear axles through self-locking differentials, while the front axle steered but took no power. Six wheels, sure, but four pushing and two only guiding. It was too heavy, cost a fortune, and was hopeless in mud. Of the 57 built, only eleven reached the Wehrmacht; the rest were judged too expensive for general military use. What the G4 really was: a display case on wheels for the regime’s parades.

Franco proved it. He took the beast hunting in the El Pardo woods, the six-wheeler stuck fast, and it had to be dragged out like a broken-down econobox. The Reich’s imposing war machine, defeated by a rut. The Germans who built it had a name for it, and it wasn’t flattering: Bonzenkübel, roughly “the big shots’ bucket,” the wagon for the party brass. The people who made it already knew what it was. Not a war machine. A rolling throne to parade the leadership around.

How many were built, and what was under the hood

Dig through the coverage and you’ll find figures ranging from 47 to 72 units. A mess, and the fault of outlets that have spent decades copying each other instead of opening a single archive.

The number is 57. Eleven delivered to the Wehrmacht through 1937, sixteen in 1938, and thirty in 1939, when the regime wanted motorized muscle on show against the backdrop of the Austrian annexation and the occupation of Czechoslovakia. Eleven, sixteen, thirty: 57. It is backed by Werner Oswald’s standard reference on the Mercedes cars of the period, which draws on the factory archive. That “47” some outlets parrot is a transcription error that fossilized.

The engine changed over the run. The first years used the Daimler-Benz M24 straight-eight, 5,018 cc and 100 hp, side valves, side camshaft. In 1937, a 5,252 cc version with 115 hp. And in 1938 the M24-II at 5,401 cc which, despite the bigger displacement, made no more power: 110 hp. Four-speed gearbox. Top speed of 42 mph (67 km/h), and not out of caution but because of the off-road tires it wore. For scale: the 1936 Mercedes 540K, using that same 5.4-liter block but with a supercharger, touched 106 mph (170 km/h). The G4 crawled along at under half that on the same base displacement. This was never a car built to go fast. It was a car built so you’d be seen riding in it.

While we’re at it, for anyone who’s read the G4 made 230 hp: false. That 230 belongs to the supercharged 770 Grosser. The G4 never topped 115 in its life.

Two details finish the portrait of what this car was really for. First: some units in the hands of party bigwigs carried rear-facing spotlights, meant to dazzle and briefly blind any car following too close. Second: the front passenger seat folded away so someone could ride standing up inside the car, to salute the crowd at parades. A vehicle designed, down to the seat, for the stagecraft.

The survivors

This is where almost everyone slips, including the ones who claim to know. You’ll read that the Spanish G4 is “the only one left.” Wrong. And the real story beats the myth.

Of the 57, at least three survive in fully authentic condition: one at the Sinsheim museum in Germany; one in the United States, which has earned a living in war movies and even opens the credits of Hogan’s Heroes; and the third in the Spanish royal collection, Franco’s. Some sources push the count of survivors in varying states to four or six, but the genuinely original cars number three.

What makes the Spanish one special isn’t that it’s unique. It’s that it’s the most complete of the three by a wide margin, so much so that the Royal Guard mechanics who tended it for decades kept it in a condition Mercedes itself would later acknowledge. Between 2001 and 2004 the car traveled to the Mercedes-Benz Classic Center in Fellbach, near Stuttgart, for an exhaustive restoration the company took on without charging the Spanish state a cent, logging it as a gift to the royal household. Three years taking it apart piece by piece. The Germans’ verdict? That it had barely been used and is the best-preserved example left in the world. That the company that built it, and that holds no G4 of its own, had to certify that the planet’s reference car is the one kept alive by army mechanics in a garage at El Pardo says more than any valuation. The ones who know, quiet in a workshop. The ones who boast, coming to see how it’s done.

The gift Franco couldn’t have cared less about

One detail captures the man better than any biography. The car arrived loaded with luxury meant to dazzle: a bespoke set of tire chains and six suitcases signed by Karl Baisch, built to slot into the trunk to the millimeter. And it drank hard: around 16 mpg (38 l/100 km) in town, on a 98-liter tank, because moving three and a half tons on gasoline has a price.

Franco didn’t care. He had no fascination with cars, so the most expensive gift of his life barely got his attention. Ordered by the Reich in December 1939, the car landed at the port of Barcelona on January 16, 1940, and drove up to Madrid under its own power. It was handed over by the German ambassador, Eberhard von Stohrer, through Franco’s foreign minister and brother-in-law, Ramón Serrano Suñer. Because this was no gift between friends: it was an interested bribe, a nudge to push Spain into the war on the Axis side. A bribe with bodywork.

And it still didn’t work. Franco used it on the odd official hunt around El Pardo and La Mancha, where it stuck fast and got towed, and little else. There was a political reason to shelve it too: once the war turned, being seen in a German car stopped being convenient, and Franco leaned on vehicles closer to the winners, Rolls-Royce, Cadillac, Buick. Hitler’s gift was parked. The most exclusive car in Spain in those years, gathering dust in a garage because its owner neither liked cars nor wanted the photo. It was forgotten so thoroughly that it was the then Prince of Asturias who, visiting the coach houses in 1998, noticed its decay and set the restoration in motion.

Gift or purchase?

The pretty version says Hitler gave the car to Franco, full stop. The paperwork says something else, and dirtier.

German sources take it as read (“Geschenk Hitlers an Franco”) and place the handover in early 1940. Francoist sources finish the postcard: registered under the plates of the Caudillo’s household and tied to a Franco birthday. Here it’s worth stopping, because the detail gets told wrong over and over: it’s been written up as his fiftieth birthday, even his fortieth, and neither fits. Franco was born on December 4, 1892, so in January 1940 he was around 47, not 50. A gift between dictators, perfect for the photo and dated to whichever age sounded best.

But the official Patrimonio Nacional placard, from the body that guards the car today, tells the version that ruins that photo: the Army Ministry paid an “agreed price” of 60,000 marks for the vehicle in 1945, though, the label says word for word, it “seems” to have been offered earlier as a gift. Translated: not even the Spanish state dares call it a gift. It records a purchase, with the shadow of an offer that never closed. A present that ended up going through the books.

Why pay for a gift? By 1945 Germany had lost. A car you flaunted in 1940 as proof of friendship with the Reich was, by 1945, burning a hole in your hands. Paying for it and logging it as a state purchase was the way to launder the politics out of it, to turn a defeated dictator’s gift into an inventory asset. The question doesn’t close here because the documentation doesn’t close it, and anyone selling you the clean version is filling gaps the sources leave open. Note the tangle of dates too: ordered December 1939, landed January 1940, registration dated December 1942, payment 1945. Line them up if you like, but not as a tidy sequence, because it isn’t one.

The ownership fight

The best act cost the Franco family dearly. In the 1980s Mercedes wanted the car back for its Stuttgart museum. The figure floated runs around a billion pesetas of the day, with other versions lower, and it exposed the question that had sat under the rug for decades: whose car is it? If it was Hitler’s personal gift to Francisco Franco the man, it belonged to his heirs. If it was a state purchase, it belonged to everyone.

Patrimonio, with the government behind it, said no. So Mercedes did the logical thing to get it: went straight to the daughter and son-in-law to encourage them to claim it as a personal gift. There was litigation. Carmen Franco eventually dropped the claim, and the car stayed put at El Pardo, in state hands. King Juan Carlos I himself is said to have flatly refused to sell it to the marque. And a legend circulates, which I give you strictly as legend because no document backs it, that the Stuttgart envoys went so far as to lay a blank check on the table. What isn’t legend is that Spain told no to a manufacturer used to nobody telling it no.

What’s left

Today the G4 is valued in the millions; some push it to 25. The figure is the least of it. What weighs is the question that number hides: is it worth that for what it is, or for who sat inside? Take Franco out of the seat and you still have the most original G4 on the planet, the one Mercedes certified as the best-preserved in the world. Take that away too and you’re left with an expensive tractor that couldn’t clear a ditch. Both are true at once, and anyone telling you only one is selling you half.

Don’t ask me to get misty about who rode in it. I look at the metal. A car has no morality and no conscience: the G4 wasn’t designed as a weapon, it was designed as a heavy Geländewagen that ended up a rolling stage prop for the regime that paid for it. Saying so glorifies nothing; it does the opposite, strips the aura, dismantles the myth, and lays bare what was always underneath, an imposing six-wheeler that needed a push. The most expensive engineering is worth exactly what you put it to work doing. And this car says it loud and silent, parked in a garage at El Pardo. Still see it as a jewel, or are you starting to see it for what it is?

Check you’re still alive.
