Today, the AMG brand is known to people around the world. It can often be found on business and premium models. However, not everyone knows about the history and technology of this division. This will be discussed in this article.
Story
The AMG brand was created over 45 years ago by two engineers, Hans Werner Aufrecht and Erhard Melcher in the village of Grossapach. The beginning of the brand dates back to the 60s. At this time, Aufrecht and Melcher were developing the special 300 SE racing engine in Daimler's design department. Despite the suspension of the concern's participation in motorsport, the engineers continued to work on this engine. The scene was Aufrecht's house in Grossapach. In 1965, their Daimler-Benz colleague, Manfred Schick, starts the German Touring Car Championship driving a car with a 300 SE engine. Modified by Atzfrecht and Melcher, the engine brings Schick ten victories. Later, the glory of true professionals in the field of modernization and improvement of Mercedes-Benz cars comes to them.
In 1967 they open the AMG engineering office. The location of the company was an old mill in Burgstall. After a short period of time, the demand for engines begins to grow, which are being refined and increased in power. Their purchasers are various racing teams.
The victory at the 24-hour race in Spa is the first major milestone in the history of the company. The victory in its own class, as well as the second place in the overall standings - all this was provided by the car AMG Mercedes, equipped with a 300 SEL 6.8 engine. Similar to heavy executive sedan, due to the engine, he easily bypassed lighter competitors. After that, the name AMG began to sound around the world and until today remains a popular brand of the Daimler concern.
AMG Technologies
In addition to boosting engines, the AMG engineering bureau is developing technologies that make driving more comfortable. Let's talk about some of them.
Dynamic characteristics
Composite materials, which have been of great help in motorsport, provide excellent performance even with the heaviest dynamics. The suspension is stiffer, provides decent control over the car. This is facilitated by a smaller body roll angle. In addition, the suspension adapts the damping to the specific driving style.
The push-button control allows the suspension to be adjusted for enhanced comfort and agility. Has sporty handling with an extra aggressive attitude gear ratios. It allows you to feel the full potential of the transmission.
A little about the transmission
Sporty dynamics require a technically sophisticated transmission. It should competently transfer engine power to the road and help the driver drive the car with maximum convenience.
The gearbox, developed by engineers from AMG, has the ability to adapt to any driver's requirements. The result is unbelievable reliability, economy, and torque-free shifting.
In addition, the driver can adjust the transmission to suit their own driving style, switching between gear modes without any problems.
Rolling arches
The AMG Bureau has developed unique technology rolling arches. Because the correct wheel from the AMG should be in the same plane with the wing, and on some the edge is bent inward, then you need to straighten it outward.
After preparing the workplace and removing the wheel, the roller is put in place. Then the edge is heated with a dryer for industrial use so that it becomes elastic. We adjust the roller and bring the edge of the wing to the outside. We ride in left side for uniformity. Approximately also roll out the arches of the rear type.
Production of the company
As part of its work to improve vehicles, the AMG division produces power units, gearboxes, interior elements, wheel disks. From latest solutions dual-type turbocharging is used for V-shaped engines, turbochargers, as well as piezo injectors with gasoline injection using a technology similar to Common Rail.
The sports car Mercedes-AMG GT 4-Door Coupe (Mercedes-AMG GT 4) is presented publicly as part of. From now on in the lineup German company three models of the Mercedes-AMG GT (Mercedes-AMG GT) - a two-seater sports car with closed body coupe, soft top convertible and 5-door hatchback officially named Mercedes-AMG GT 4-Door Coupe. In our review, the new 2018-2019 Mercedes-AMG GT 4-Door Coupe - photos and videos, price and equipment, technical specifications of a sports 5-door hatchback, declared by the manufacturer as a 4-door coupe. Sales of the 5-door Mercedes-AMG GT will start in the summer of 2018 price from 120-125 thousand euros for a 435-horsepower all-wheel drive Mercedes-AMG GT 53 4Matic +.
If the two-door Mercedes-AMG GT and Mercedes-AMG GT Roadster are drafted into the ranks of Mercedes to compete with, then the Mercedes-AMG GT 4-Door Coupe will try to knock down the arrogance of the model. And take my word for it, the novelty will make it easy.
It should be noted right away that a large 5-door hatchback with a comfortable 4-5-seat interior and luggage compartment, capable of receiving 395-1324 liters depending on the position of the rear seat backs, is not a platform brother of the AMG GT coupe and roadster models (the original platform with two lever suspension front and rear wheels, as well as located at rear axle"robot" Getrag (transaxle scheme)). At the heart of the Mercedes-AMG GT 4 is the MRA modular bogie with a two-lever front and a multi-lever rear suspension, and automatic transmission located just behind the engine at the front of the vehicle. So the siblings of the novelty are the new generations and.
The question immediately arises why Mercedes-Benz needs two car Mercedes-Benz CLS and Mercedes-AMG GT 4-Door Coupe in the sporty "four-door coupe" niche?
- First, machines with different types bodies: CLS - 4-door sedan stylized as a coupe, and GT 4 - 5-door hatchback also stylized as a coupe.
- Secondly, the 5-door GT looks more aggressive and brutal than the sedan's platform brother.
- Thirdly, the Mercedes-AMG GT 4-Door Coupe will not have modest versions with diesel engines, rear wheel drive and a price tag in the region of 70,000 euros, but only the most powerful gasoline engines, four-wheel drive and a price starting from a mark of at least 120-125 thousand euros.
As confirmation, we invite you to get acquainted with technical specifications new Mercedes-AMG GT 4-Door Coupe 2018-2019, offered from the start of sales in three versions with powerful petrol turbo engines.
Mercedes-AMG GT 53 4Matic+ with 3.0-litre six-cylinder engine(435 hp 520 Nm), supplemented by a starter-generator of the EQ Boost system (22 hp 250 Nm), which helps the car with intensive acceleration. Transmission automatic 9-speed (AMG Speedshift TCT 9G), full drive transmission 4Matic + (by default, the drive wheels are rear, and a multi-plate clutch, if necessary, connects the front wheels, thus ensuring the machine all-wheel drive). Such a technical arsenal provides a 5-door curb weight of 1970 kg with acceleration dynamics from 0 to 100 km / h in 4.5 seconds and a maximum speed of 285 km, declared fuel consumption of 9.1-9.4 liters. Spring suspension, disc brakes on all wheels.
Mercedes-AMG GT 63 4Matic + with 4.0-liter V8 Biturbo (585 hp 800 hp), equipped with new two-line turbochargers, liquid intercooler and half-cylinder deactivation system. Box AMG gear Speedshift MCT 9G with a wet clutch instead of a traditional torque converter, of course, the proprietary 4Matic + all-wheel drive system, as well as air suspension and rear steering wheels in turns with a pair of electric actuators (at speeds up to 100 mph they turn in the opposite direction of the front wheels, and at more high speed turning in the same direction as the front). A car with a curb weight of 2025 kg shoots up to 100 mph in 3.4 seconds, maximum speed 310 mph, average consumption fuel 11.0-11.2 liters.
Mercedes-AMG GT 63 S 4Matic + with a 4.0-liter V8 Biturbo petrol (639 hp 800 Nm), AMG Speedshift MCT 9G automatic transmission, 4Matic + all-wheel drive system, supplemented by a rear differential with electronic control. The transmission additionally received a drift mode with complete shutdown ESP and front-mounted multi-plate clutch. In drift mode, the 5-door sports car is exclusively rear-wheel drive. Suspension, of course, pneumatic with thrusters rear wheels. Most powerful motor accelerates a car with a curb weight of 2045 kg to the first "hundred" in 3.2 seconds, a top speed of 315 mph, an average fuel consumption of at least 11.2 liters.
As standard equipment for all modifications of the 5-door Mercedes-AMG GT, the AMG Track Pace system is offered to help you choose optimal mode for driving on the race track (Slippery, Comfort, Sport, Sport+, Race and Individual), supplemented by a belay system with several prescribed levels driving skills(Basic, Advanced, Pro and Master). The higher the level, the less the electronics interfere with driving, tracking and reading as many as 80 parameters.
I would like to note that the new 5-door Mercedes sports car in terms of dynamic and speed characteristics surpassed all modifications Porsche Panamera. For example, the 550-horsepower Porsche Panamera Turbo picks up the first “hundred” in 3.6-3.8 seconds and accelerates to a maximum of 306 mph, and the hybrid and most powerful in the Panamera Turbo S E-Hybrid line with 680-horsepower power plant capable of accelerating from 0 to 100 mph in 3.4 seconds and reaching a top speed of 310 mph, but ... this is only enough to compete with the Mercedes-AMG GT 63 4Matic +, but not with the Mercedes-AMG GT 63 S 4Matic +. It's hard to imagine what a full-fledged Mercedes-AMG GT 4 hybrid with an 800-horsepower power plant will be capable of.
We figured out the technique, and let's get back to the exterior and interior of the chic 5-door hatchback, positioned concern Daimler like a 4 door coupe. The exterior design of the body, as mentioned above in our review, is aggressively brutal, stylish, bright and charismatic, as befits an expensive sports car. Available LED matrix headlights, a powerful body complemented by a mass of aerodynamic chips - splitters, spoilers, active blinds (adjustable rear spoiler, and for an extra charge even made of carbon fiber), huge wheels - 255/45 R19 on the front axle and 285/40 R19 on the rear axle of the Mercedes-AMG GT 53 4Matic + and Mercedes-AMG GT 63 4Matic + versions and larger 265/40 R20 and 295/35 R20 in the powerful modification of the Mercedes-AMG GT 63 S 4Matic +. If desired, 21-inch forged aluminum wheels with 275/35 R21 tires at the front and 315/30 R21 at the rear can be installed on any version of the 5-door for an extra charge.
The interior of the Mercedes-AMG GT hatchback, at the request of the customer, can be either a 5-seater with a rear sofa designed for three, or a 4-seater with two separate seats for rear passengers. At the same time, all the seats in the cabin are sports with powerful lateral support and anatomical backrest profile. The driver's and front passenger's seats are like racing car class GT3. The design of the front of the cabin Mercedes-AMG GT 4-Door Coupe combination of the front panel from the soplatform Mercedes-Benz CLS and the tunnel of the two-door Mercedes-AMG GT.
Available analog (for Mercedes-AMG GT 53) or digital panel instruments (Mercedes-AMG GT 63 and Mercedes-AMG GT 63 S versions) with a screen diagonal of 12.3 inches, advanced multimedia system with a similar dashboard display size, sports steering wheel with touchpads, background LED lights interior (64 colors to choose from), driver and front passenger seats with electric adjustment, ventilation and heating, rear seats heated and ventilated, three or four zone climate control and ground electronic systems security, assistants and assistants from the system automatic braking And adaptive cruise control, working with the help of radars to the Drive Pilot complex, capable of independently driving a car on the highway.
Mercedes-AMG GT 4-Door Coupe 2018-2019 video test
If you enter the salon official dealer Mercedes in Moscow, then along with the main model line you will see numerous hatchbacks, sedans and SUVs the lineup AMG. The prices here, I must say, are quite high. So, if the “cheapest” G-class SUV at the moment - we are already on the site that they are also called “Geliki” - costs about 6.7 million rubles, then the Mercedes-AMG G 65 model will cost from 21 million rubles.
Why is this a big difference in prices? And what does this have to do with the "AMG" prefix in the title? We will try to give an intelligible answer to this question.
Mercedes-AMG division
This division was created back in 1967 and its main task was to tune production cars for use in sports. We remind you that the concept of "tuning" in Germany and in the West in general has a completely different meaning - this is not a change in the exterior, but an improvement in technical characteristics.
Based on this, it becomes clear why there is such a difference in price between the two Gelendvagen models.
Just look at the characteristics of the engine:
- Mercedes G 350 d for 6.7 million rubles is equipped with a three-liter 6-cylinder diesel engine 245 horsepower;
- on the Mercedes-AMG G 65 model, there is a 6-liter unit for 12 cylinders, the power of which reaches as much as 630 hp. - which is why it is considered one of the most powerful all-wheel drive SUVs in the world.
Even if we look at the prices of more modest Mercedes car classes, such as C-class sedans, we see a similar situation there. Yes, the most available model The S-180 costs 2.1 million, the S-200 with 4Matic all-wheel drive will cost 2,480,000 rubles. Well, for tuned cars you will have to pay much larger amounts:
- AMG C 43 4Matic - 3.6 million;
- Mercedes-AMG C 63 - 4.6 million;
- AMG C 63 S - 5,120,000 rubles.
Well, the difference in engines is also noticeable. The last model on the list squeezes her 4 liter engine 510 horses. And the Mercedes C 180 is only 150.
Initially, such advanced cars were intended for participation in motorsport: the 24-hour Spa race, the Grand Prix at the Nurburgring, the FIA GT, Le Mans. In addition, Mercedes-AMG supplies its cars as safety and medical cars for Formula 1 circuit racing.
Naturally, rich people liked such powerful cars and they gladly began to buy them at such immodest prices. So, Mercedes CLK The GTR, which was assembled at the AMG division plant in Affalterbach, entered the Guinness Book of Records as the most expensive stock car. The recording was made in 2000 and the car at that time cost just over 1.5 million US dollars. They were equipped with a 6.9-liter engine producing 612 hp. The car accelerated to hundreds in 3.8 seconds, and the maximum speed reached 310 km / h.
It is clear that tuning concerns not only engines. AMG Division also engaged in other developments:
- branded automatic boxes dual clutch gears;
- light alloy wheels;
- ultralight alloys based on aluminum and magnesium;
- interior and exterior elements.
To achieve such excellent performance succeeds by attracting the best engineers who manage to find completely new solutions. For example, thanks to the development of a specially shaped cylinder head, it became possible to install on cars such powerful engines for 8-12 cylinders.
The peculiarity of the work of the division is that the engines are assembled manually, and according to the principle "One person - one engine". Agree that company employees are required to highest degree professionalism to get the job done.
The company employs approximately 1,200 employees who assemble up to 20,000 Premium class cars a year. Thus, if you are looking for really worthy and reliable cars, pay attention to Mercedes-Benz-AMG.

One of the reasons for the impossibility of successful conception is inconsistent hormonal levels. In gynecology, this is a common reason why a married couple has to agree to IVF. To identify this health problem, an analysis for AMH is taken. Experts call this organic substance a valuable marker of the functional reserve of the ovaries.
What is AMG
The development of pathology is appropriate for hormonal imbalances in the female body. Anti-Müllerian hormone is an organic product, the production of which is not controlled by the brain, but depends entirely on the functionality of the ovaries. Such a substance until the onset of puberty of the female body maintains a constant concentration. In the future, it varies within certain limits, is affected by provoking factors, age-related changes in the body. The maximum concentration reaches 20-30 years, and during menopause it is practically reduced to a minimum.
AMH analysis
The indicated laboratory test is called the "Extended Efort-Test", and the need for it arises in the absence of the desired pregnancy after repeated attempts by the couple to conceive a child. In addition, the gynecologist strongly recommends taking an analysis for the AMH hormone with the following deviations, anomalies of the female body:
- suspicion of infertility under unclear circumstances;
- high levels of follicle-stimulating hormone;
- several unsuccessful IVF attempts;
- diagnosis of polycystic ovaries;
- control positive dynamics antiandrogen therapy;
- detection of granulosa cell tumors of the ovaries;
- impaired sexual development of adolescents.
AMH hormone is normal
Index allowable limits excludes a number of reasons why a woman cannot become pregnant. Therefore, laboratory testing should not be avoided. The rate of anti-Müllerian hormone in women depends on age, and for a period of 20-30 years is 4-6.8 ng / ml. There is also a normally low indicator, the permissible value of which varies between 2.2-4 ng / ml. Doctors say that the norm of the hormone AMH in women of reproductive age is such a range - 2.2-8 ng / ml. Any deviations eloquently indicate a pathological process.
AMH increased
Any disruption of the hormonal background in the female body does not go unnoticed, since when they appear, external, internal changes are observed. In addition, a woman will not be able to become pregnant until the underlying disease is completely cured. A characteristic indicator changes under the influence of pathological factors, returns to normal after their elimination, the use of therapeutic measures. Influence such a jump bad habits present in human life. So, AMH is elevated in the following clinical pictures:
- specific mutation of the AMH receptor;
- bilateral cryptorchidism;
- normogonadotropic anovulatory infertility;
- absence ;
- monitoring antiandrogen therapy.
Low AMH
With age, the concentration of the hormone in the blood decreases rapidly, and this phenomenon has its own limits. If the real indicators go beyond the established intervals, this means that not everything is in order with health in the body. Low AMH may be associated with a violation of the menstrual cycle, or it may be the result of provoking factors. Anti-Mullerian hormone can be lowered by:
- obesity in older reproductive age;
- anorchism;
- delayed sexual development;
- hypogonadotropic hypogonadism;
- gonadal dysgenesis;
- decrease in ovarian reserve.
AMG hormone - when to take
If a woman cannot become pregnant for a long time, it is necessary to undergo an examination. This information is also useful for men who have no way to become a father. This is the first and main indication when donating the AMH hormone to both sexual partners. If the anti-Müllerian hormone continues to be produced in insufficient or excessive concentrations, additional hormonal treatment is indispensable. Other indications when analysis is required are presented below:
- disturbed menstrual cycle;
- diagnosis of diseases in a female way;
- previous surgery;
- repeatedly unsuccessful IVF;
- late reproductive age of pregnancy planning;
- impaired ovarian function;
- premature sexual development.
How to donate AMH hormone
If an analysis is needed AMG hormone- what is it, the attending physician will prompt. The features of the further treatment regimen, its therapeutic efficacy depend on the results obtained. In order to increase the reliability of the result, while at the same time significantly reducing the need for re-examination, it is required to responsibly take the test for anti-Mullerian hormone. The optimal period for blood sampling is 3-5 days of the menstrual cycle.
In order to properly take the AMG hormone, on the eve it is required to eliminate bad habits, avoid stressful situations, do not eat food 12 hours before the diagnosis, and reduce physical activity. Scheduled venous blood sampling is appropriate only for a healthy body. After a long illness, it is better to wait a few weeks until the body gets stronger.
How to increase AMH
If the blood serum is donated according to the specified rules, the result can be trusted. A low level of AMH is a symptom of pathology. It is required to stabilize the reference values. To increase AMH, the patient needs.
Mercedes-Benz has been hatching plans for a four-door version of the AMG GT for a couple of years, and Geneva Motor Show 2018 was finally presented with a production version of such a model, which received the rather intricate name AMG GT 4-Door Coupe.
In the front and in the back new model really resembles the original supercar in many ways, but at the same time there are full-fledged four doors without frames, a sloping roof, windows in rear pillars and impressive overall length. In terms of body shape, the car resembles the Porsche Panamera, which is seen as its main competitor.
