History · 1967–today
Two engineers. One old mill. More power.
In 1967, two ex-Daimler engineers started building racing engines in a former mill. Their initials now sit on the fastest cars Mercedes has ever made.
Spa-Francorchamps, July 1971. Through the forests of the Ardennes comes something that has no business being here: a full-size Mercedes luxury sedan, painted bright red, flared at the arches, howling past touring cars half its weight. It will run like that for twenty-four hours. When it finishes — first in class, second overall — the paddock has already given it a name: die Rote Sau. The Red Pig.
The two men behind it had no factory, no dealer network and no blessing from Stuttgart. What Hans Werner Aufrecht and Erhard Melcher had was an engineering office in an old mill, an unshakable belief in the Mercedes V8, and a conviction that would carry three letters from rural Swabia onto every racetrack on earth: there is always more power.
Chapter I · 1965–1971
Racing engines, after hours.
Aufrecht and Melcher met in the development department at Daimler-Benz, working on the 300 SE racing engine — until the company walked away from motorsport altogether in 1965. The program died; their obsession didn't. In Aufrecht's house in Großaspach, the pair kept developing the engine in their own time.
It worked. In 1965, their colleague Manfred Schiek took a privately entered 300 SE with their engine to ten victories in the German Touring Car Championship. Word spread quickly through the paddocks: the two quiet engineers from Daimler could make a Mercedes move.
In late 1966 Aufrecht left Mercedes and persuaded Melcher to follow. In 1967 they registered a company whose name was longer than its payroll: Aufrecht Melcher Großaspach Ingenieurbüro, Konstruktion und Versuch zur Entwicklung von Rennmotoren — an engineering office for the design and testing of racing engines. The world would only ever use the initials.
Headquarters was a former mill in Burgstall an der Murr, a village north of Stuttgart. Within a few seasons, an engine from the mill was something private racing teams simply had to have.
Chapter II · 1971
The wrong car wins.
For their assault on the Spa 24 Hours, Aufrecht and Melcher chose the least likely weapon on the grid: the 300 SEL 6.3, an air-suspended autobahn flagship. They bored its V8 out to 6.8 liters and extracted 428 PS, stripped what they could, flared the arches over wide racing wheels — and painted it red.
Driven by Hans Heyer and Clemens Schickentanz, the AMG 300 SEL 6.8 won its class and crossed the line second overall, ahead of fields of purpose-built, far lighter machinery. A luxury sedan had humbled the touring-car establishment, and the name AMG went around the world with it.
The original car had an unsentimental afterlife — sold to the French firm Matra and used up as a test vehicle. The Red Pig you can see today is a faithful recreation Mercedes later built for its own collection; the legend needed a body to live in.

The nickname
Rote Sau.
The Red Pig — for the bright paint and for the sheer improbable bulk of a two-tonne luxury sedan hunting sports cars through the Ardennes. AMG never chose the name and never needed to: it said everything about the company in three syllables. Take the most dignified Mercedes there is, and make it misbehave.
Chapter III · 1976–1990
The tuner of Affalterbach.
Spa changed the customer base. Racing teams still called, but so did doctors, industrialists and film stars who wanted their road cars to feel like the Red Pig ran. In 1976 AMG moved to a purpose-built workshop in Affalterbach with about a dozen employees. Melcher stepped back from the partnership and stayed in Burgstall doing what he loved most — engines — while Aufrecht built the business.
Through the late seventies and eighties, AMG became the most famous name in the Mercedes aftermarket: engine conversions, deep front aprons, Recaro interiors, and five-spoke alloys so recognizable they made the company's reputation on sight. A flat little three-letter badge on a trunk lid became a warning to whatever was ahead.
The masterpiece came in 1986. AMG lifted the S-Class V8, crowned it with its own 32-valve twin-cam cylinder heads, and dropped it into the mid-size W124 sedan. The 5.6-liter version made around 360 PS and pushed past 300 km/h — press on both sides of the Atlantic called it the fastest sedan in the world, and the car simply became the Hammer.
A complete Hammer cost well over three times the price of the 300 E it started life as. It didn't matter. The waiting list — and the legend — grew, and in 1988 Daimler-Benz itself came calling: AMG would run Mercedes' works assault on the German Touring Car Championship, the DTM.
Chapter IV · 1990–1999
Joining the star.
On the racetrack the partnership was already delivering: the boxy 190 E 2.5-16 Evolution II became a DTM icon, and in 1992 Klaus Ludwig took the drivers' championship in an AMG-Mercedes. In 1990 the handshake became a contract — a cooperation agreement with Daimler-Benz that put AMG products in Mercedes showrooms with full factory warranty, and AMG engineers inside official development programs.
The first child of the agreement arrived in 1993: the C 36 AMG, a 3.6-liter straight-six C-Class developed jointly in Affalterbach and Stuttgart. It was the first AMG you could order from any Mercedes dealer — the moment the tuner became a product line.
The C 36 also picked up a very public side job: from 1996 it served as the official Formula 1 safety car, beginning a relationship between AMG and Grand Prix racing that has never paused since. Every time the field slowed anywhere in the world, an AMG led it.
Demand outran the old structure. On 1 January 1999, DaimlerChrysler took a majority stake and Mercedes-AMG GmbH was born; Aufrecht's racing operation was spun off into his own firm, HWA, back in Burgstall. On 1 January 2005 the takeover was completed — AMG belonged to Mercedes, entirely.
Chapter V · 2005–2014
One man, one engine.
Full ownership did not make AMG more corporate — it made it more itself. In 2006 came the M156, a 6.2-liter, 6,208 cc V8 and the first engine developed entirely in Affalterbach, a high-revving naturally aspirated monument that powered a generation of 63-badged cars.
Each one was built the AMG way: a single technician assembles a single engine from first bolt to last, then signs an aluminum plaque on the intake — Ein Mann, ein Motor. One man, one engine. In an industry of anonymous assembly lines, every AMG V8 carries a name.
Then Affalterbach built a whole car. Unveiled at Frankfurt in 2009, the SLS AMG was the first Mercedes designed and built from scratch by AMG — an aluminum gullwing supercar answering the 300 SL half a century on, its hand-built 6.3 V8 rated at 571 PS. The apprentice from the mill was now shaping the brand's halo car.
Chapter VI · 2014–today
A brand of its own.
In 2014 the second all-AMG car, the AMG GT, arrived — and with it, Mercedes-AMG became a full brand rather than a badge. The range stretched from 43 and 53 models to the hand-built 63s, and the three letters that once marked a single red sedan at Spa now accounted for well over a hundred thousand cars a year.
The racetrack never let go. AMG GT3s and GT4s race in customer hands on every continent, and the works Formula 1 team carries the name — Mercedes-AMG Petronas took eight consecutive constructors' championships from 2014 to 2021, one of the longest winning streaks in the sport's history.
For its fiftieth birthday in 2017, AMG promised the impossible: a road car powered by an actual Formula 1 engine. Five years of development later, the Mercedes-AMG ONE delivered — a 1.6-liter V6 turbo-hybrid from the championship-winning F1 car, four additional electric motors, and a combined 1,063 PS.
In November 2022 it lapped the Nürburgring Nordschleife in 6:35.183 — at the time, the fastest road-legal production car ever around the circuit. Fifty-five years after Burgstall, the mill's descendants were setting the pace for everyone.

1,063 PS
From 428 PS out of 6.8 liters at Spa to 1,063 PS out of 1.6 — the brief Aufrecht wrote in 1967 has never changed. Only the numbers have.
Three letters, six eras.

Epilogue
Still an engineering office.
Nearly three thousand people work in Affalterbach today, in a campus of test benches and design studios that Aufrecht's dozen employees of 1976 would not recognize. And yet the essential transaction is unchanged from the mill: bring us a Mercedes, and we will find the rest of it. The 63-series V8s are still assembled by one person each, and still signed by hand.
Erhard Melcher, the quiet half of the initials, kept building engines in Burgstall long after his name had become one of the most valuable in the industry. That may be the truest measure of AMG: it grew from two men into a global brand without ever deciding it was finished. There is, after all, always more power.
