Test Mercedes-AMG GT 63 S 4 Doors Coupé

The Geneva Motor Show 2018, celebrated in March, was the place chosen by the Mercedes-AMG to present its last great creation. Responds to the name of Mercedes-AMG GT 4-Door Coupé and becomes the brother with saloon coupe body (or four-door coupe) of the spectacular AMG GT Coupe and Roadster .

Mercedes cited us this Monday to try out some of the new additions to the AMG family , among which, without a doubt, the Mercedes-AMG GT 63 S 4 doors Coupé . After some elbowing with the rest of our press colleagues, we arrived first to take the keys to this model with a 4.0-liter biturbo V8 engine with 639 HP and 900 Nm , whose price starts in the 195,500 euros .

When the brand unveiled the whole model I was disappointed. It's a very sporty and elegant car , I agree, but I expected a much more aggressive aesthetic . Mercedes-AMG had long been creating high expectations, stating that it would be like a two-door AMG GT, but with two rows of seats and four entrances.

In the end, they presented a car of more than 5 meters with a very refined aesthetic. I expected something more "cañero", more in the style of his two-door brothers, because that was what he had understood through the statements made by the brand. Be that as it may, the theory and technical data say that this Mercedes-AMG GT 63 S must be a machine coming from beyond the grave, or from the sky . Let's check it out.

​​Elegant exterior design at the same time sporty

The four-door AMG GT has a very stylized design that combines with aggressive features . On the front, the famous Pan-American grill is especially noticeable, which is already common in this GT family, as well as the huge lower air intakes that show the intercoolers on both sides and, by the way, look like leave them very unprotected against the Chinese that can jump.

The active aerodynamics allows moving the slats of the central area, closing the passage of the air when not it is necessary a high cooling of the engine and its auxiliary components, thus improving the aerodynamics.

Following the side, the silhouette is very, very soft, but we already perceive that we are not facing a very small car. The fall of the roof appears practically from the B-pillar, which gives it a very special side view .It should be noted that, despite being called AMG GT 4 doors, in fact is a five-door vehicle , because we have a boot lid and no lid. At the edge of the same an active spoiler is deployed to modify the downforce, which we can also control from inside.

Following the rear, we read the typical inscriptions of the model and mechanical version in chrome finish. But the most striking point is in the lower area, where it appears a marked, but not exaggerated, diffuser in black color that houses four exits of escape , which emanate a beautiful melody when the V8 of 4 liters come alive.

What's inside?

The interior design of the Mercedes-AMG GT 4-door Coupé is pretty more accomplished than that of the 2-door AMG GT. The perceived quality in the passenger compartment is very good (which we could not say when we tested the GT Roadster), far superior to that of its range brothers.

It is true that this new vehicle is already three years with his brothers of range of two doors, so it is logical that there is a evolution in aspects such as technology and quality . However, it is noted that the German brand has sought to offer a better experience to customers, with better materials and finishes , although this requires them to raise the final rate of the vehicle. And, in the front, we feel practically like in an S-Class.

The first details that call my attention when sitting in the driving position are your steering wheel and your center console. If the steering wheel is already striking, the Performance steering wheel of our test unit (standard on the GT 63 S), which is lined in Napa, also has two satellite controls under the horizontal radios with small TFT screens .

The right-hand drive allows you to quickly vary the driving mode, while with the left we vary some mechanical settings like the exhaust sound or the management of the transmission with two keys. This is so so that we do not have to separate our hands from the steering wheel to find the configuration that we want from the vehicle. The only thing is that, at least in the unit tested, crunch a lot when pressed, which has left me a bit cold. Maybe it's just a problem with this test unit and not something normalized, but I can not confirm it.

Regarding the center console , the main design is similar to the one we saw last year during the test of the Mercedes-AMG GT Roadster. However, now it looks much more advanced, including also small TFT screens .The interior space of the front seats is large. The driving position is low (but not as much as in the other AMG GTs) and the center console is not as intrusive as it may appear in the images. The amount and volume of slots is good for a car like this.

To access the rear seats we must be careful not to hit the head in the upper frame. Once seated, the legroom is good, although not as much as we would expect for a car over 5 meters, being quite more fair to the head . I, with my height of 1.76, I am at the limit of rubbing my hair on the ceiling.

The ability to personalize for this second row is also great. In fact, we can configure it with four seats of individual seats, four seats with a large central console between half or five seats. In the second case, you can also consult the real-time performance information of the vehicle, charge the smartphones wirelessly and make a multitude of adjustments such as changing the climate control or the interior lighting.

Trunk: Although it is called 4 Doors, it is actually a 5 doors

It is curious that Mercedes-AMG has opted for the denomination GT 4 Doors when in fact it has a tailgate . This gives it greater practicality, although it is not exactly convenient to load and unload it because the bottom edge is too high and it is hard to get to the bottom of the trunk.

The volume of the trunk is 456 liters , and can be extended (if we acquire optional folding seats) to 1,324 liters. The capacity of load is quite good for a car of these benefits - but something small for its external size - and it will be enough to carry four suitcases of compact size. The Porsche Panamera, which is one of its main rivals, offers almost 500 liters.

Engines available for the Mercedes-AMG GT 4 Coupé Doors

We started getting into on the job and we started talking about your mechanics offer . The Mercedes-AMG GT 4 Doors Coupé is offered, with a version of six cylinders in line and two V8. In the following table we leave you all the data:

V.On the other hand, the brand has already informed that a fourth variant, more accessible, with denomination "43" would be incorporated into the range with 367 CV, although for the moment the date of arrival in the Spanish market is unknown.

Other advanced technical solutions

Beyond the engines, the AMG GT 4 doors has interesting solutions that allow you to provide a great behavior without therefore penalize in comfort . lightweight materials such as aluminum and carbon fiber have been used in certain elements, as well as others of very high strength to protect occupants in case of impact.

Interesting also the aforementioned active aerodynamics , varying the ventilation to the engine compartment depending on the temperature inside, as well as the extensible rear spoiler that varies its position to improve aerodynamic support and performance.

Following the same line, the dynamic engine mounts allow the vehicle to be increased or decreased, as well as the smoothness of the vehicle. response of the same. No less interesting is the AMG Ride Control +, the adaptive pneumatic suspension system, which allows to regulate the damping behavior depending on the driving mode selected and the type of driving carried out by the driver.

For its part, the rear axle steering provides, in addition to better stability at high speed, a lot of agility both on roads and narrow and when maneuvering in town. At less than 100 km/h the rear wheels turn a few degrees in the opposite direction to the front, giving the feeling that we are driving a vehicle with less battle . When exceeding 100 km/h the rear axle rotates in the same direction as the front, giving greater stability and poise on fast roads .

The company of Affalterbach has integrated several driving modes , common in almost all new cars on the market. However, in the RACE mode of this vehicle we can select several ways to manage the traction, including a Drift Mode function that prioritizes sending torque to the outer rear wheel to facilitate lateral sliding.

At the wheel of the Mercedes-AMG GT 63 S 4 Doors Coupé

Now yes, and After having described all the visual and technical part in static, it is time to see what this model is capable of . As I told you at the beginning, I tried the most powerful version of this sports four-door, ie the Mercedes-AMG GT 63 S 4-door Coupé. Foot brake, start button and the V8 4 liters begins to sing for those four impressive exhaust tails.

I adjust the seat and the steering wheel, all by electrical settings, I familiarize for a few moments with all the controls and enter the destination point in the browser, not without some complications for not being completely familiar with this new infotainment and navigation system.

I put the transmission in D mode I start the race . Despite the large exterior dimensions of the bodywork, the maneuverability is better than expected thanks to the rear axle steering, although logically it is more complicated to maneuver than, for example, a Class C.Not very far from the fluidity that a car like the S-Class transmits. Nor is it not at all dry or rough when overpassing bridge joints. The double-clutch gearbox with 9 gears has a very good configuration, both when starting the race, and when passing from one speed to another.

It is a delight to drive it at normal rates in this driving mode. It is surprising how it is isolated and how comfortable it is , although it stops when we think about its price of almost 200,000 euros. But this is a 639 CV sport , so, now that I've arrived at more tacked and fun roads , I activate the Sport driving mode. The gearbox reduces a couple of gears, the steering gains weight, the engine becomes more reactive and the suspension also hardens.

I increase the pace a little , but without exceeding because the great width of the vehicle and the narrowness of the lanes give much respect. Little by little and with good lyrics. The body barely leans when we draw at a high pace and transmits a lot of confidence, although it is true that filters a lot of sensations to the driver.

Despite the dimensions, the AMG GT 4 Doors Coupé does not cling to very twisty roads

I reach a Stop and I can not resist. Sport + driving mode, button to increase the exhaust sound and right pedal to table . Instantly my companion and I were glued to the comfortable seats while the speedometer adds tens at a bestial pace, the gear changes are almost imperceptible, while the roar of the escape increases our senses.

Not a single jerky jerk due to traction losses and the traction control indicator has barely turned on a couple of times. In less than 4 seconds I reach the maximum speed of the road, so I am forced to cut gas and behave with a civilized person ... My partner and I look at each other and we can not help but smile. What a nonsense !

As a curiosity, the front seats have instant adjustments to the sides to hold us well in the corners. I explain. If we draw a left-hand curve, the right side of the seat is inflated so that we do not slide to the outside . A curious solution. In the first corners I noticed it as something strange at the same time effective, but after a few kilometers it was totally unnoticed.

We continue our short route through narrow curved roads and, Although it does not invite to run too much for its size, the Mercedes-AMG GT 63 S 4-door Coupé is very agile. The bodywork still contains the inertias of 2 tons of weight and is shown quite agile , also helped by a high precision of the direction. We do not go at a devilish pace, but the behavior seems very good, with a great motricity when leaving curves accelerating strong. Not a single trace of loss of grip.

My time is running out at the controls of this 4-door AMG-GT, but before I have only a dozen kilometers left by highway >The V4 warning light appears on the instrument panel, which indicates the disconnection of four of the eight cylinders to save fuel and reduce pollution.

It is at this moment that, when reconsidering, I think about the little sense that this type of vehicle has in our market . It is a coupe model with four doors that can take you to 315 km/h, but in Spain we can not exceed 120 km/h. From stationary and accelerating to the bottom, we only need about 4 seconds to reach that speed.


Mercedes-AMG has tried to to convince us that it is a very suitable car both for circuit and for traveling since it was presented in Geneva. I have not been able to drive it on a circuit - a real shame - and I'm sure it's very fast, but I do not think many AMG GT 4-door customers sign up for Track Day to squeeze this 2-ton beast to the limit. For this they will have, for example, an AMG GT-R, or some other similar circuit machine.

It's time to change to the passenger seat, write down my notes and then tell everything here and reconsider. 195,500 euros . It is a very high price, but the truth is that it surprises the versatility of this model in the sense that you can go to a really fast and agile rhythm with 2 tons, feeling everything under control despite its 640 CV, and at the same time make a long trip with unblemished comfort .

I think that's what surprised me most about this car, the ability to completely change character just by switching from one driving mode to another. Hopefully soon I will have the opportunity to change the open road by a wide circuit to see if I have to give the reason or not to Mercedes that this car is totally valid to enjoy on circuit.

To finish, The most direct rival of the AMG GT 63 S 4 Puertas is the Porsche Panamera, which recently launched its second generation. The case is that the Panamera Turbo is far from its power, with 550 HP, so the rival level of performance would be the Porsche Panamera Turbo S E-Hybrid, which yields 680 and 850 Nm, but has the condition of being a hybrid vehicle. Its starting price in Spain is about 190,000 euros.
