Mercedes-AMG GmbH, commonly known as AMG, is the high-performance division of Mercedes-Benz. Based in Affalterbach, Baden-Württemberg, Germany, AMG designs, builds, and customizes Mercedes-Benz vehicles to deliver more power, sharper handling, and a more aggressive look than their standard counterparts. AMG models are typically the most expensive and highest-performing versions in each Mercedes-Benz class.

The name "AMG" stands for Aufrecht, Melcher, and Großaspach — the surnames of its two founders and the birthplace of one of them. Originally an independent company, AMG has been a wholly owned subsidiary of the Mercedes-Benz Group since 2005.

AMG was founded in 1967 by two former Mercedes-Benz engineers: Hans Werner Aufrecht and Erhard Melcher. The full original name of the company was AMG Motorenbau und Entwicklungsgesellschaft mbH (in English: "AMG Engine Production and Development Ltd."). They set up shop in a former mill in Burgstall an der Murr, a small town near Stuttgart, and began designing and testing racing engines.

Aufrecht had been passionate about motorsport while working at Mercedes-Benz, but the company's management at the time was reluctant to get involved in racing. Frustrated by the lack of opportunity, Aufrecht left and convinced Melcher to start the business with him. Very quickly, the engines they built became sought after by private racing teams.

AMG's big breakthrough came at the 1971 24 Hours of Spa race in Belgium. They entered a heavily modified Mercedes-Benz 300 SEL 6.8 — a large, heavy luxury sedan that nobody expected to compete with lighter, purpose-built race cars. The car, nicknamed the "Red Sow" (Rote Sau in German), won its class and finished second overall. This stunning result put AMG on the map internationally.

Throughout the 1970s, AMG grew steadily, equipping more and more Mercedes models with performance upgrades. Customization became a major part of the business — customers could order everything from engine upgrades to body kits and custom interiors. In 1976, AMG moved its main operations to a purpose-built workshop in Affalterbach (which remains its headquarters today), while racing-engine development stayed in Burgstall. Around this time, Erhard Melcher stepped down as a partner but continued working at the Burgstall facility.

During the 1980s, AMG offered a wide range of performance packages as a fully independent company. Customers could order increased engine displacements, performance cylinder heads, aggressive camshafts, sport suspensions, alloy wheels, body kits, and luxury interior upgrades.

A landmark moment came in 1984, when Melcher developed a completely independent cylinder head with four valves per cylinder, establishing AMG as a true engine manufacturer — not just a tuner.

In 1986, AMG created what many consider its most legendary car: "The Hammer". This was a W124 E-Class sedan with an AMG-tuned 5.6-litre V8 engine stuffed inside. At the time, it was claimed to be the world's fastest passenger sedan — reportedly faster than a Lamborghini Countach when accelerating from 100 to 190 km/h. The Hammer became an icon, especially in the United States, and cemented AMG's reputation for building extraordinarily fast cars out of ordinary-looking sedans.

In 1990, AMG and Daimler-Benz (the parent company of Mercedes-Benz at the time) signed a cooperation agreement. This was a turning point: AMG products could now be sold and serviced through Mercedes-Benz's worldwide dealer network, dramatically boosting demand and customer trust.

In 1993, the partnership produced its first jointly developed car: the Mercedes-Benz C36 AMG, based on the first-generation C-Class. That same year, AMG was officially recognized as a trademark by the German Patent Office.

On 1 January 1999, DaimlerChrysler (as the parent company was then known) acquired 51% of AMG's shares, and the company was renamed Mercedes-AMG GmbH. The racing-engine division was split off into a separate company called HWA (from Hans Werner Aufrecht's initials), which continued to operate in Burgstall.

Finally, on 1 January 2005, Aufrecht sold his remaining shares, and Mercedes-AMG became a wholly owned subsidiary of what is now the Mercedes-Benz Group.

AMG vehicles stand apart from standard Mercedes-Benz models in several key ways:

• More powerful engines — AMG models use specially tuned or entirely different engines, often with turbocharging or larger displacements.
• Sportier appearance — AMG cars typically feature more aggressive body styling, larger air intakes, wider fenders, unique grilles, and distinctive exhaust tips.
• Better handling — Sport-tuned suspensions, larger brakes, and performance tires give AMG models sharper cornering and more responsive driving dynamics.
• More carbon fibre — Weight-saving carbon-fibre components are used extensively.
• Unique transmissions — AMG models often use performance-oriented automatic or dual-clutch transmissions with faster shift times.

AMG models are usually badged with two numerals (like "E 63"), while regular Mercedes-Benz models use three (like "E 350"). These numbers don't always indicate the actual engine size — they are often a tribute to heritage models, such as the famous Mercedes-Benz 300 SEL 6.3. For example, the modern E 63 AMG actually has a 4.0-litre V8, not a 6.3-litre engine.

The main AMG tiers, from entry-level to flagship, are:

• "35" — Entry-level AMG. Uses an "AMG-enhanced" 2.0-litre turbocharged four-cylinder engine. These engines are not hand-built.
• "43" — Mid-range. Historically used a 3.0-litre V6 biturbo; newer models use a tuned 2.0-litre four-cylinder with mild-hybrid technology.
• "45" — Top-tier four-cylinder. Uses a hand-built 2.0-litre turbocharged engine producing over 400 hp — one of the most powerful production four-cylinder engines in the world.
• "53" — Uses a 3.0-litre inline-six with a turbocharger, electric compressor, and 48-volt mild-hybrid system. A well-rounded balance of power and efficiency.
• "63" — The traditional heart of the AMG lineup. Uses a hand-built 4.0-litre twin-turbo V8 (M177/M178 engine). These are the high-performance flagships of most Mercedes model lines.
• "E Performance" — The newest tier, combining combustion engines with plug-in hybrid electric motors for extreme power outputs (over 800 hp in some models).

One of AMG's most famous traditions is the "One Man, One Engine" philosophy. For higher-performance AMG models (the "45", "63", and above), each engine is hand-assembled from start to finish by a single technician at AMG's factory in Affalterbach. When the engine is complete, the builder attaches a signed metal plaque to it — a mark of personal craftsmanship and pride.

According to Mercedes-Benz, there are only about 50 AMG engine builders. This approach contrasts sharply with traditional assembly-line production, where engines pass through many workers on a conveyor belt. The "One Man, One Engine" method is both a quality-control measure and a powerful marketing symbol of AMG's dedication to craftsmanship.

Note: The entry-level "35" and "43" models, as well as the Formula 1-derived engine in the Mercedes-AMG One, do not follow this hand-built process.

AMG's motorsport involvement deepened in the late 1980s when it partnered with Mercedes-Benz on the 190 E race cars for the Deutsche Tourenwagen Meisterschaft (DTM), the prestigious German touring car championship. Between 1988 and 1993, the AMG-prepared 190 E race car scored 50 DTM victories, establishing AMG as a serious force in professional racing.

When DaimlerChrysler acquired a majority share of AMG in 1999, the racing department was spun off into HWA AG. Since 2000, HWA has built and operated the Mercedes entries in the DTM (later called Deutsche Tourenwagen Masters).

AMG has a significant connection to Formula One. Since the end of 2011, the Mercedes factory F1 team has used the AMG branding, racing as Mercedes-AMG Petronas. Under this name, the team won a historic streak of Constructors' Championships from 2014 to 2021 and helped Lewis Hamilton secure multiple World Drivers' Championships.

Several AMG road cars have also served as the official Formula One Safety Car, including the AMG GT and AMG GT R. Since 2021, Mercedes-AMG shares the safety car role with Aston Martin.

Since 2010, AMG-based GT race cars — first the SLS AMG GT3 and then the AMG GT3 — have competed in GT racing series around the world, including the 24 Hours of Nürburgring, the Blancpain Endurance Series, Super GT, and many others.

The Mercedes-AMG One is a limited-production hypercar that brings genuine Formula One technology to the road. It uses a modified version of the 1.6-litre turbocharged V6 hybrid engine from a Mercedes F1 car, combined with four electric motors, for a total output of around 1,049 hp.

Only 275 units were produced, each priced at approximately US$2.72 million. All were sold before production began. In November 2022, the AMG One set a lap record at the Nürburgring Nordschleife, completing the 20.8 km track in 6 minutes and 35 seconds — making it the fastest road-legal production car to ever lap the circuit. In September 2024, it improved this to an even faster 6:29.09, becoming the first road-legal production car to break the 6:30 barrier.

The AMG "Hammer" was an E-Class (W124) sedan fitted with a 5.6-litre DOHC V8. It was claimed to be the world's fastest sedan at the time of its release and became a legend in automotive culture, especially in the United States.

The car that made AMG famous. A massive luxury sedan modified with a 6.8-litre V8, it shocked the racing world by finishing second overall at the 1971 Spa 24 Hours against far lighter and more purpose-built competitors.

AMG does not only work on Mercedes-Benz vehicles. The company has supplied engines and technology to several other automakers:

• Pagani — AMG has supplied V12 engines for the Pagani Zonda, Huayra, and Utopia hypercars.
• Aston Martin — Since 2013, Aston Martin has used AMG-developed V8 engines and electric/electronic components in its vehicles. The Mercedes-Benz Group owns a stake in Aston Martin as part of this partnership.
• Lotus — The Lotus Emira uses AMG's M139 four-cylinder engine.

In earlier decades, AMG also developed performance variants of some Honda and Mitsubishi models sold in South Africa.

Mercedes-Benz offers AMG Line or AMG Styling packages on many of its standard models. These packages add sportier-looking bumpers, grilles, wheels, and interior trim — but they do not add any extra engine power or AMG-specific mechanical upgrades. A car with an "AMG Line" package is not the same as a true AMG model; it is a cosmetic upgrade only.
