Mercedes-AMG V297 IAA 2021 1X7A0040

Mercedes-AMG GmbH, commonly known as AMG, is the high-performance subsidiary of Mercedes-Benz AG. AMG independently hires engineers and contracts with manufacturers to customize Mercedes-Benz AMG vehicles. The company has its headquarters in Affalterbach, Baden-Württemberg, Germany.

AMG was originally an independent engineering firm specializing in performance improvements for Mercedes-Benz vehicles. DaimlerChrysler AG took a controlling interest in 1999, then became the sole owner of AMG in 2005. Mercedes-AMG GmbH is now a wholly owned subsidiary of Mercedes-Benz AG, which is in turn owned by the Mercedes-Benz Group.

AMG models typically have more aggressive looks, better performance, better handling, better stability and more carbon fibre than their regular Mercedes-Benz counterparts. AMG models are typically the most expensive and highest-performing variant of each Mercedes-Benz class.

AMG variants are usually badged with two numerals, as opposed to regular Mercedes-Benz vehicles, which have three (e.g. "E 63" as opposed to "E 350"). The numerals do not always indicate engine size, but are rather a tribute to earlier heritage cars, such as the 300 SEL 6.3 litre. For example, newer-model AMG V8s such as the E 63 actually have 4.0L V8s.

The world's first stand-alone Mercedes-AMG dealership, AMG Sydney, was opened in Sydney, Australia in 2018.

History

AMG was founded as a racing engine forge in 1967 under the name ''AMG Motorenbau und Entwicklungsgesellschaft mbH'' (German for 'AMG Engine Production and Development Limited') by former Mercedes-Benz engineers Hans Werner Aufrecht and Erhard Melcher in Burgstall an der Murr, near Stuttgart. The initialism 'AMG' stands for Aufrecht, Melcher and Großaspach (Aufrecht's birth town). In 1976, most of AMG moved to Affalterbach, with the racing-engine development remaining at the old location in Burgstall. At this time, Erhard Melcher ceased to be a partner, but he continued to be an employee at the Burgstall location.

In 1993, with AMG having become a high-profile purveyor of modified Mercedes-Benz cars, Daimler-Benz AG and AMG signed a contract of cooperation, allowing AMG to leverage Daimler-Benz's extensive dealer network and leading to commonly developed vehicles (the first one being the Mercedes-Benz C36 AMG, in 1993).

On 1 January 1999, DaimlerChrysler AG (as it was called between 1998 and 2007) acquired 51 percent of AMG shares, and AMG was renamed to Mercedes-AMG GmbH. Racing engine development was divested and continues to exist in Burgstall under the name HWA (Aufrecht's initials). On 1 January 2005, Aufrecht sold his remaining shares to DaimlerChrysler, and since then, Mercedes-AMG GmbH has been a wholly owned subsidiary of the Mercedes-Benz Group.

Development of the product range

AMG started off by designing and testing racing engines. It expanded its business into building ''custom'' road cars based upon standard Mercedes cars. AMG initially produced a range of unofficial upgrade and accessories packages mainly for the Mercedes-Benz R107 and C107 (1971–1989 SL roadster), Mercedes-Benz W116 (1972–1980 S-class), Mercedes-Benz W123 (1976–1985 E-class predecessor), Mercedes-Benz W124 (1984–1997 E-class), Mercedes-Benz W126 (1979–1992 S-class), Mercedes-Benz R129 (1989–2001 SL roadster), and Mercedes-Benz W201 (1990–1993 C-class) models.

During the early 1980s and up until 1990, AMG offered a variety of engine performance packages, alloy wheels and styling products as an entirely independent company from Daimler-Benz. In 1990, AMG signed a co-operation agreement with Daimler-Benz, and AMG options and cars were then offered in Mercedes-Benz showrooms; in 1999 Daimler AG, then known as DaimlerChrysler AG, bought the controlling share of AMG and made them part of the official Mercedes-Benz line-up.

Typical AMG performance enhancements, which the buyer could custom order, included increased engine displacements (5.2 litre, 5.4 litre), performance top ends with port and polished heads and intake, lightened valve train, and more aggressive cams. The DOHC 32V engine had also just been developed and was the pinnacle of AMG performance. A Getrag five-speed manual transmission could be ordered from AMG, and Mercedes had not offered a manual transmission V8 since the early 1970s.

The performance wheels offered during the same period were 15-inch or 16-inch ATS AMG Five Spoke Road Wheels, commonly referred to as Pentas. Penta was actually a UK-based company that supplemented the high demand for the AMG wheel at the time with a replica and only a very slight styling difference, but they were not made or endorsed by AMG. The genuine AMG wheels were often coupled with an AMG performance suspension package that included uprated and lowered springs, and re-valved shock absorbers.

Another popular cosmetic upgrade were the AMG body kits. These ranged from subtle front spoilers to aggressive Wide Body kits for the W126 coupes (reaching more than $700k on the classic market in 2022). Other options included Recaro seats, smaller diameter steering wheels, instrument clusters, chrome delete option (all brightworks colour-coded or painted satin black), refrigerators, shift knobs, hi-fi stereo systems, custom upholstery and enhanced interior wood packages.

The release of the AMG Hammer sedan in 1986, based on the W124 E-Class, took AMG's performance modifications for a fast midsized sedan to a new level. AMG made the world's fastest passenger sedan at the time, nicknamed the Hammer, by squeezing Mercedes 5.6-litre V8 tuned by AMG to 360 hp into a midsized sedan. It was very aggressive for the era, with 32-valve cylinder heads and twin camshafts, and said to be faster than the Lamborghini Countach from 60 to 120 mph. Later models were even more powerful and introduced the 17-inch AMG Aero 1 Hammer wheels. 1986 was also the year Mercedes introduced the 560 M117 engine. This provided yet another opportunity for customers to order the largest AMG displacement available at the time, the 6L 100 mm bore SOHC or DOHC engines available for both the W126 coupe and sedans.

Through the early 2000s, AMG focused principally on supercharged V8 and V6 engines, but the company officially abandoned this technology in 2006 with the introduction of the naturally aspirated 6.2 L M156 V8. On 16 January 2006, Mercedes-AMG Chairman Volker Mornhinweg told AutoWeek that the company would use turbocharging for higher output rather than supercharging. For 2011, AMG released the M157 5.5L bi-turbo V8, which has supplanted the M156 in its full-sized cars such as the S-Class and CL-Class (and is trickling down to the CLS, E-Class, and ML-class). In 2012, Mercedes-AMG Chairman Olla Kallenius said that Mercedes-AMG will not produce diesel engines to compete with BMW's tri-turbo diesels (BMW M Performance range).

Although there were some AMG models in the 1980s with manual transmissions, almost all recent models have used automatics (5G-Tronic and later 7G-Tronic with Speedshift), in contrast to ''BMW M'', which used manual and recently automatic transmissions (the current type being a dual clutch transmission). Starting in 2009, however, AMG began adopting the seven-speed AMG SpeedShift MCT automatic transmission.

Although these are considered the most well known in-house tuning divisions, Mercedes-AMG has a considerably different philosophy than BMW M. Compared to BMW M, Mercedes-AMG is "less narrow in its sporting focus, yet still combining sledgehammer performance with relaxed handling, cultured comfort, and practicality".

While founders Hans Werner Aufrecht and Erhard Melcher had emphasized proper racing cars, Mercedes-AMG had diverged considerably from this philosophy in recent years, with their offerings being well known for straight-line acceleration but poor handling dynamics. However, current Mercedes-AMG chairman Volker Mornhinweg has urged the division to return to its roots of building sports cars.

Motor racing

In the late 1960s and early 1970s, AMG entered the big Mercedes-Benz 300SEL 6.3 V8 saloon, affectionately named the "Red Sow", in the 1971 Spa 24 Hours, and the European Touring Car Championship. AMG and Mercedes worked together on Mercedes-Benz W201 cars for the 1988 Deutsche Tourenwagen Meisterschaft (DTM, German Touring Car Championship). AMG was made the official partner.

When DaimlerChrysler acquired a majority share of AMG in 1999, the motor racing department was divested into HWA AG. Their first car was the ill-fated Mercedes-Benz CLR. Since 2000, HWA builds and runs the cars for Deutsche Tourenwagen Masters (DTM), as well as the M271 engine tuned for use in Formula 3.

In 2000, an extensively modified one-off Mercedes-Benz AMG CLK 55 was built by the AMG Factory as a purpose-built race car to compete in the 2001 Targa Tasmania 7 day road race. Mick Doohan was the works Mercedes-Benz AMG driver.

Six successive lightly modified Mercedes-Benz AMG models (including, most recently, a C190 GT R) have acted as the safety cars for the FIA Formula One World Championship.

Since 2010, the SLS AMG GT3 and the AMG GT3 has been competing in GT competitions around the world, such as the FIA GT3 European Championship, Blancpain Endurance Series, Blancpain Sprint Series, VLN, 24 Hours of Nürburgring, British GT Championship, Super GT, Australian GT Championship, Bathurst 12 Hour, Dubai 24 Hour, Macau GT Cup and Pirelli World Challenge.

In late 2011, after the end of the Formula One season, Mercedes GP Petronas announced that it would be using the AMG branding for its F1 efforts, changing its name to Mercedes AMG Petronas for the 2012 season onwards.

Three AMG E-Class V8 Supercars competed in the Australian Supercars Championship from 2013 to 2015, operated by Erebus Motorsport under the AMG Customer Sports Program.

Relationship with Pagani

AMG also provides engines for the Zonda and Huayra cars. The M297 7,291 cc displacement V12 engines were originally used in the 1995 SL 73 AMG. It is the largest displacement naturally aspirated engine provided by AMG and is now exclusively used by Pagani.

Relationship with Aston Martin

On 25 July 2013, Aston Martin Lagonda Ltd and Daimler AG announced moves towards a technical partnership with Mercedes-AMG GmbH. The deal will see Aston Martin access significant Mercedes-AMG GmbH and Mercedes-Benz Cars' resources, allowing the development of bespoke V8 powertrains and the use of certain components of electric/electronic architecture. Daimler AG now owns a stake of 5% of non-voting shares in Aston Martin, joining existing shareholders Investment DAR, Adeem Investment and Investindustrial. The technical partnership will support Aston Martin's launch of a new generation of models and newly developed bespoke V8 powertrains.

For the 2021 and 2022 Formula One World Championship, the German marque shared the role as the official Safety Car supplier with Aston Martin.

Relationship with Lotus

AMG also provides engines for the Lotus Emira. The M139 I4 engine that was originally used in the CLA 45 AMG.

AGM Trim

Mercedes-Benz allows customers to upgrade nearly any model by adding an AMG trim or styling package. So customers can customize Mercedes cars to look exactly like an AMG car, minus the all-important AMG engine. AMG trim can include a rear spoiler, body styling, deep front air dam, 18” or 19” AMG style wheels, sport front seats, sport steering wheel, AMG floor mats, sport suspension and sport brakes.

Current AMG models

All AMG engines - with the exception of the "35" M260 2.0 L Inline-4 Turbo and "43" M276 3.0 L V6 Bi-Turbo engine, as well as various other "43" and "53" models using the new M256 inline 6 engine - are hand built using a "one man, one engine" philosophy at the current AMG plant in Affalterbach, Germany. To signify this, each AMG engine builder stamps the engines they produce with an engraved plaque depicting their signature. According to Mercedes-Benz, there are only about 50 AMG engine builders.

As part of the official Mercedes product line, the AMG models are sold side by side with regular production models, unlike those offered by other Mercedes tuning firms such as Brabus.

Launched in the UK market in April 2015, the 4-litre ''M178'' V8 uses an unusual configuration where the position of the intake and exhaust are reversed, to create a more compact engine and hence vehicle design. This "hot inside v" configuration, as AMG calls it, has the exhaust gasses exiting into the central v area of the engine block where the engine's twin turbochargers are also mounted.

Previous AMG models

In addition to the models listed above, there were also predecessors to the current AMG models.

"65" M275 6.0 L V12 Bi-Turbo

The models listed below were powered by a variant of the Mercedes-Benz M275 engine.
* 2004–2013 S65 AMG
* 2004–2014 CL65 AMG
* 2004–2011 SL65 AMG
* 2012–2018 G65 AMG
* 2012–2018 Mercedes-AMG SL 65
* 2014–2019 Mercedes-AMG S 65
The AMG power-plant has an all-new design of the bi-turbo system, which features larger turbochargers and a new, more powerful charge-air cooling system, and the increase in the engine displacement (to 5980 cc) as well as many other engine design measures. This allows it to produce a claimed 621 horsepower and of torque.

"65" models used a 5-speed automatic transmission for a long time, as the newer 7G-Tronic wasn't able to handle the torque from the V12 engines. This was changed with the introduction of 2012 SL 65 AMG, which uses the same AMG SpeedShift MCT transmission as the rest of the AMG line-up.

Coinciding with the facelift of the CL-Class for the 2011 model year, the 2011 CL 65 AMG had an enhanced engine. AMG redesigned the exhaust gas turbochargers and added new engine electronics. It produced 621 horsepower, pushing the car from in 4.2 seconds (0.2 seconds faster than the 2011 CL 63), with an electronically limited top speed of . The update also improved fuel economy and reduced carbon emissions by 3.5% over the outgoing model.

"63" M157 5.5 L V8 Bi-Turbo

The models listed below were powered by the M157 variant of the Mercedes-Benz M278 engine.
* Mercedes-AMG CLS 63 (W219)
* Mercedes-AMG E 63 (W212)
* Mercedes-AMG G 63 (W463)
* Mercedes-AMG GL 63 (X166 pre-facelift)
* Mercedes-AMG GLE 63 (W166 facelift)
* Mercedes-AMG GLS 63 (X166 facelift)
* Mercedes-AMG M 63 (W166 pre-facelift)
* Mercedes-AMG S 63 (W222 pre-facelift)
* Mercedes-Benz SL-Class (R231)#SL 63 AMG (2012–), Mercedes-AMG SL 63 (R231)


Rumoured in 2009 and confirmed in 2010, AMG developed the M157, a 5.5-litre V8 with direct fuel injection and Twin-turbo, twin turbochargers. Power is rated at up to at 5,250-5,750rpm with a peak torque of made between 2,000rpm and 4,500rpm (the amount of power and torque depends on model, but these are the maximum ratings). Both engines are mated to Mercedes-Benz's 7G-Tronic#AMG SpeedShift MCT, 7-speed dual-clutch transmission, MCT transmission.
Unlike the M156 naturally aspirated 6.2 L V8, which was developed entirely within AMG, the M157 is based upon the Mercedes-Benz M278 engine, M278 used in the regular Mercedes-Benz S-Class and CL-Class. The M157 boasts 25% better fuel economy (10.5 litres per 100 kilometres versus 14.4 L/100 km in the European driving cycle) over the M156, meaning it avoids the US Gas Guzzler Tax for the first time ever, despite having up to 47 horsepower more. The M157's increased torque from both the regular version and performance package means the engine can be shifted into a taller gear sooner, keeping engine revs and fuel consumption to a minimum. The new M157 has an engine start/stop mode and is lightweight at 204 kg. The M157 is said to be ideal for powering full-size sedans such as the S-Class, but the older M156 remains in production, as its more precise throttle response is still well suited to smaller sportier models (the C-Class), until the 2015 model arrives, which is powered by a 4.0 liter V8.

5.5 L V8 BiTurbo models carry the "63" model designation, shared with the 6.2L V8 models. Visually, the 2011 S 63 AMG is differentiated from the 2010 model (itself face-lifted over the 2009 S 63) by the more angular design of the chromed dual exhaust tips, which also sport embossed AMG logos, as well as new forged wheels. For the CL 63 AMG, the new M157 engine coincides with the facelift of the CL-Class for the 2011 model year.

Despite common belief, 63 AMG models are typically faster than their 65 AMG counterparts. An S 63 AMG accelerates faster and handles better than an S 65 AMG (due to 4-wheel drive and decreased weight), and an SL 63 AMG accelerates faster than an SL 65 AMG due to decreased torque, lower weight, and better balance by use of the V8.

Since 2013, AMG models with the S-Model package feature all-wheel drive, which allows for better handling and better acceleration. The Mercedes-Benz CLS 63 AMG S has been tested to accelerate to 60 mph in just 3.2 seconds, with a quarter mile time of 11.6 seconds. This made it the quickest production sedan at the time. MotorTrend tested the 2014 E 63 AMG S with the M157 engine to produce an estimated and .

The Mercedes-Benz C-Class (W202)#AMG models, C 43 AMG (model years 1998–2000) was powered by a naturally aspirated V8 engine from the M113 family, but at a reduced displacement of Mercedes-Benz M113 engine#M113 E43, 4.3L, hence the '43' designation.
* The Mercedes-Benz M113 engine#M113 ML 55, other configuration is a similar unit but with a highly efficient Twin-screw type supercharger, Lysholm type twin screw supercharger, as manufactured by Eaton. This supercharger is found in the rest of the AMG 55 models, which are typically midsized or larger vehicles. According to Mercedes, the ''published'' output varies from to and to , depending on various methods of power measurements and different Engine Control Unit, ECU programming, in accordance with nation-specific requirements. For instance, the E 55 AMG's engine was at the low end, yet nonetheless it was still Mercedes-Benz's fastest sedan at the time, while the SL55 AMG's engine had the top output. Mercedes has claimed that a more restrictive exhaust system was responsible for cutting output on the E 55 AMG, however some enthusiasts have managed to bump up horsepower to 505 on the E 55 by incorporating some parts from the SL 55.

The supercharged 5.4 L 24 valve V8 engine was mated to the Speedshift 5-speed automatic transmission, which has a torque capacity of , as the newer 7G-Tronic introduced in 2003 is limited to , which is not enough to handle the torque from the supercharged V8.

The V8 Mercedes-Benz W220#Mercedes-Benz S 55 AMG, S 55 AMG had an output comparable to the V12-powered S600 throughout its production. The S 55 AMG (2001–02) was outfitted with a 5.4 L V8 engine while the later versions (2003–06) sported the same motor, but supercharged to a rated . The S600 (2001–02) was outfitted with a 5.8L V12 engine while the later versions (2003–06) sported a twin-turbocharged (or Bi-Turbo) 5.5L V12. The justification for having two models with the same power is that the S 55 AMG is sportier and more responsive, while the costlier S600 is more luxurious with a smoother ride.

AMG phased out both the naturally aspirated and supercharged 5.4 L engines in favor of the new Mercedes-Benz M156 engine, M156 V8 beginning in 2006, which was paired with 7G-Tronic. However, some enthusiasts were disappointed because the naturally aspirated M156 produces less torque than the supercharged M113K.

For the Model Year 2009:
* Mercedes-Benz M113 engine, M113 5.4 L "55" V8 models (Naturally aspirated engine, naturally aspirated)
**Mercedes-Benz SLK-Class (R171)#AMG models, SLK 55 AMG
* Mercedes-Benz M113 engine, M113 5.4 L "55" V8 models (Supercharger, supercharged)

"63" M137 6.3 L V12

The "63" badging was used on the short-lived 2001 Mercedes-Benz S-Class (W220), S 63 AMG, 2001 Mercedes-Benz CL-Class (C215), CL 63 AMG and 2002 Mercedes-Benz G-Class#2005 update, G 63 AMG. These were produced in limited quantities for one month and only offered through AMG to select customers in Europe and Asia, purportedly state leaders. The CL 63 AMG was the rarest C215 CL of all, and just 26 examples were built in November 2001 (51 plate), with some UK being and one for France registered in March 2002. These had a base price of Pound sterling, £110,000 (~USD, US$200,000). The G 63 AMG was the rarest W463 of all with just 5 examples built in September 2002 and sold in Germany at over €250,000 each.

These are powered by a naturally aspirated 6.3L V12 producing . This engine is based on the Mercedes-Benz M137 engine, M137 5.8L V12 used in the S 600 and CL 600, but the AMG variants have a larger displacement, a new management system, a new crank case and cooling system, weight-optimized pistons, and a new camshaft with greater valve lift and modified valves. of torque are available between 2500–5800rpm with a peak of at 4400 rpm while horsepower grows by almost 80 over the 5.8L V12. It is mated to a 5-speed automatic transmission. The 2001 S 63 AMG V12 had 100 hp more than the 2001 S 55 AMG, and was a few tenths faster.

"60", "73", "70", "55"

The Mercedes-Benz SL-Class (R129)#AMG offerings, Mercedes-Benz SL-Class (R129) had several AMG variants during its production run from 1989 to 2001.

The SL 60 AMG was the most numerous of these rare cars. Sold from 1993 to 1998, it used a 6.0 litre V8 engine producing at 5500 rpm. AMG claimed a 0– speed of 5.6 seconds. Its top speed was limited to , but with the limiter removed, it was capable of approximately . AMG later unofficially conceded that was more like 5.0 seconds and the engine produced between 405 and 410 bhp.

Extremely rare was the SL 73 AMG, sold through Mercedes-AMG in 1995, and offering the most powerful V12 engine ever put into an SL up to that time. After a brief hiatus, the SL 73 was offered again from 1998 to 2001. The same 7.3 L V12 engine, V12 was later used by Pagani in the Zonda.

Even rarer is the SL 70 AMG (7.0 L (7055 cc) V12 engine).

The SL 55 AMG was sold in the R129 body style from 1998 to 2001 in limited numbers (5.4L V8, at 5500 rpm). It was the predecessor of the production Mercedes-Benz R230#AMG, R230 SL 55 AMG sold later, albeit was normally aspirated in the R129 and not supercharged as in its R230 successor.

"63" M156 6.2 L V8

The "63" Mercedes-Benz M156 engine, M156 is currently in production in the C 63 AMG and tuned as the M159 in the SLS AMG, although there were many models that were previously in production.

This naturally aspirated V8 will also be used to replace most of the "55" models. The ''published'' output according to Mercedes varies from on the C 63 AMG, to on the C/CLK/R/ML/GL/S/SL/CL/E 63 AMG.

The 2008 S 63/CL 63/SL 63s that used the M156 engine at 518 horsepower edged out that of the S600/CL600/SL600, the latter powered by the 510 horsepower 5.5-liter twin-turbo V12, while also having a higher redline. However, the S600/CL600/SL600 is more expensive and has more torque at . The S 63/CL 63/SL 63, however, do have quicker acceleration times than their S600/CL600/SL600 counterparts and are the fastest in the lineup in 2014, due to the added weight and torque of the 65s, thus decreasing the 0-60 times and the handling limits.

Compared to the "55" supercharged 5.4 L V8 engine—which was restricted to the Speedshift 5G-Tronic five-speed automatic transmission, as it had a torque capacity of —the reduced torque of the "63" M156 6.2L V8 means it can be mated with the more efficient 7G-Tronic, which can withstand a limit of . Despite the reduction in torque, the increased horsepower and more efficient transmission enable the ''63'' models to match or surpass the acceleration of the "55" models. Most of the M156-engined models used the 7G-Tronic automatic transmission, however the more recent 2009 SL 63, 2010 E 63, and 2012 C 63 use the 7-speed 7G-Tronic#AMG SpeedShift MCT, MCT transmission.
