You’ve seen them everywhere. From the neon-drenched streets of Miami to the rugged mountain passes of the Alps, the Mercedes-Benz G-Class—affectionately known as the G-Wagon—is a silhouette you just can’t mistake. It’s the ultimate "if you know, you know" vehicle. But here’s the thing: if you think this German powerhouse is actually built by Mercedes in Germany, you’re only half right.
Honestly, the story of who makes the G-Wagon is one of the most fascinating "outsourcing" successes in automotive history. It’s a tale that involves an Iranian Shah, a mountain in Austria, and a manufacturing giant you’ve probably never heard of unless you’re a total car nerd.
The Secret Factory in Graz
Most people assume that every Mercedes rolls off a line in Stuttgart or Bremen. Not the G. Since the very first model chugged to life in 1979, the G-Wagon has been hand-assembled in Graz, Austria. The company behind the curtain is Magna Steyr.
They aren't just a "supplier." They are a contract manufacturing titan. While Mercedes-Benz owns the brand, handles the marketing, and provides the engines (especially those hand-built V8s from AMG), Magna Steyr is the one actually turning the wrenches and welding the steel.

Why Austria?
It goes back to the early 70s. Mercedes-Benz wanted to build a serious off-roader—something that could go anywhere and do anything. They didn't have a dedicated facility for such a niche, rugged project. So, they partnered with Steyr-Daimler-Puch (which later became part of Magna).
The location wasn't an accident. The factory sits at the foot of the Schöckl mountain. This isn't just scenic; it’s a brutal testing ground. Every G-Wagon design has to survive the "Schöckl certificate"—a grueling 2,000-kilometer test on a track that would tear most SUVs into scrap metal.
If you ever find yourself in Graz, you might see these boxy beasts crawling up inclines that look vertical. That’s the birthplace. That’s where the DNA is forged.
Wait, So Who Actually Designed It?
This is where it gets kinda messy. The G-Wagon wasn't just a corporate brainstorm. It was actually suggested by the Shah of Iran, who was a major Mercedes shareholder at the time. He wanted a tough military vehicle.
Mercedes handled the "vision" and the engineering standards, but the technical development was a joint venture. They even formed a company called Gelandefahrzeug Gesellschaft mbH (try saying that five times fast) specifically to manage the project.
Basically, Mercedes-Benz provided the luxury and the brand prestige, while the Austrians provided the 4x4 expertise. Even today, while the modern 2026 models are packed with MBUX "Hyperscreens" and ambient lighting that looks like a nightclub, the core manufacturing remains in those same Austrian hands.

The 2026 Shift: Electricity and Expansion
We are currently living through the biggest change in the G-Wagon’s 45-year history. You might have heard of the G 580 with EQ Technology. That’s the all-electric version.
You’d think moving to EV would mean Mercedes would bring production back to Germany to use their new battery plants, right? Nope. Magna Steyr is still the answer to who makes the G-Wagon, even the electric one.
In fact, Magna recently extended their contract with Mercedes-Benz to keep building the G-Class until at least 2034. They even developed the "eDS Duo" drive units—the tech that allows the new electric G to do a "G-Turn" (spinning 360 degrees on the spot like a tank).
A Few Surprising Stats
- 500,000+: That’s how many G-Wagons have rolled off the line in Graz since 1979.
- The "Puch" Years: In some markets like Austria and Switzerland, the G-Wagon wasn't even sold as a Mercedes until the year 2000. It was sold as a Puch G.
- Hand-Built: Despite the $150k+ price tag, these things are still largely assembled by hand. It takes roughly 100 hours to build one G-Class, which is why the waitlists are usually miles long.
Does It Matter That Mercedes Doesn’t "Make" It?
Some purists get weird about contract manufacturing. They think if it isn't made by the name on the badge, it’s a "fake."
That’s total nonsense here.
Magna Steyr is arguably better at building low-volume, high-complexity vehicles than almost any mainstream factory in the world. They’ve built everything from the BMW Z4 to the Toyota Supra and even the Fisker Ocean (though we don't talk about that one as much).
The G-Wagon is their crown jewel. Because they aren't a massive, rigid assembly line, they can handle the weird stuff—like the crazy 6x6 versions or the 4x4² models with portal axles. A standard Mercedes factory in Germany is optimized for thousands of C-Classes. The Graz factory is optimized for craftsmanship and ruggedness.
The "Little G" is Coming
Looking ahead into late 2026 and 2027, there’s a new player: the "Baby G."
Mercedes has confirmed a smaller, more affordable (relatively speaking) version of the icon. While the full-sized G-Wagon will stay in Graz, there is still debate in the industry about where the "Little G" will be born. Some rumors point to Mercedes' own plants in Hungary, while others suggest Magna might get the nod again.
Actionable Insights for Buyers and Fans
If you’re in the market or just a fan tracking who makes the G-Wagon, here is what you need to know:
- Check the Door Jamb: Open the driver's door of any G-Wagon. You’ll see the manufacturing plate. It specifically lists "Magna Steyr Fahrzeugtechnik" alongside Mercedes-Benz. It’s a badge of honor, not a secret to hide.
- The "Schöckl" Badge: Look for the small round badge on the B-pillar that says "Schöckl Proved." This is a nod to the Austrian mountain where the vehicle was perfected. If it doesn't have that heritage, it's not a real G.
- Appreciation Potential: Because the production is limited by the physical capacity of the Graz factory (they can't just "turn up the volume" like a robot-heavy plant), G-Wagons hold their value better than almost any other luxury SUV.
- Service is Still Mercedes: Even though Magna builds it, your local Mercedes-Benz dealer handles the warranty and service. You aren't hunting for Austrian parts in a specialized shop.
The G-Wagon is a bit of a freak of nature. It’s a military truck dressed in a tuxedo, designed by Germans, requested by an Iranian, and built by Austrians. It shouldn’t work. But forty-five years later, it’s still the king of the hill.
