First Coupe Mercedes-AMG GT 4 doors 2019: barely tamed

The coupe's life can be fun but rarely practical: if you like the Mercedes-AMG GT Coupe, but need more space to carry your friends, family or sports equipment, the Mercedes-AMG coupe GT 4 doors 2019 may well be suitable. Even if you're not always aware of the current trend to call four-door cars, you can not resist one thing. In a way, with the help of the basic GT 53 4-Door Coupe model, Mercedes-AMG has managed to manufacture some of the most practical and extravagant sports sedans that money can buy.

Your attention naturally goes to the most extreme version, the 2018 Mercedes-AMG GT 63 4-Door Coupe. Under the hood is a hand-made AMG V8 engine that produces 577 horsepower and 590 lb-ft of torque. The GT 63 S becomes even more outrageous, with 630 horsepower and 664 lb-ft. Not a word yet on the official prices for this 600 horsepower family rocket, but Mercedes has said that if you could afford a $ 200,000 Panamera Turbo S, you should probably do cross-shopping.

When you let about 600 horses play, you have every interest in doing so. Mercedes-AMG has chosen to pass the GT 63 S at the Circuit of the Americas (COTA) to test its talents. It's a challenging course, as well as major elevation changes that challenge professional riders and the depth of torque your vehicle of choice can bring.

The power is certainly there, as you hope, but the degree of control is also surprising. Keeping in mind the basic concept of slow-in, with the long-term approach, I've tried variously to come into hard, soft mode and just to see how the "slow-in" concept works. AMG could handle it. 0-60 mph arrives in just 3.1 seconds, and with the AMG Dynamic Select system set to race mode, the GT 63 S swiveled around the turn and galloped to set my personal 158 mph record on the straight . A lot of noise, yes, it does not lack speed, but all delivered with amazing ease.

This is partly because of the way AMG builds V8 engines, putting twin-scroll turbochargers between the cylinder banks rather than outside of them. This means that they are closer, which makes them more reactive: there are fewer tubes for the exhaust gases and, by placing the catalytic converters in the "V", AMG also improves the thermal efficiency. The result is an excellent response to the throttle with better power distribution, even at low speeds.

Go fast, therefore, will not be a problem. With an empty weight of over 4,460 pounds wet, however, ensuring that the GT 63 S would stop at the other end of the line gave me a moment of pause. For this, Mercedes-AMG opts for 15.4 "x 1.4" internally ventilated carbon ceramic perforated brake discs at the front, with 6-piston aluminum fixed calipers and brake discs. 14.2 "x 1.0" carbon ceramic. the back, with one-piston aluminum floating calipers. Even after a whole day of harsh treatment, I did not feel once that the brakes were giving way or erasing.

Michelin, meanwhile, delivered specially formulated rubber, giving the GT 63 S a set of 265/40 / ZR 20 tires at the front and 295/35 ZR 20 at the rear. What's important is that it's not just about specials of the day. AMG GT 4-Doors can be fast, but they are also supposed to be family carriers. This meant that the tires had to be able to cope with everyday road conditions, such as alleviating bumps and avoiding road noise and vibrations.

The last part is aero. The most notable is the active rear spoiler, integrated into the trunk. Not only does it extend as needed and retract when it is not, but it takes place in five different stages, all automatically controlled according to the speed of the vehicle. At 49 mph, for example, the spoiler increases to enhance the strength of support and aerodynamic efficiency when the car builds up speed. Stage 2 arrives as soon as it reaches 87 mph to increase the support force, while Stage 3 does not reach 161 mph, providing support force and stability maximum.

Step 4 is at 112 mph when you want the perfect combination of airflow and stability for a high speed cruise – not that you should ever see it, at least legally , on American roads. Finally, Step 5 offers the maximum extension to act as an airbrake, which helps you when you slow down aggressively.

I may not have seen step three, but COTA still offered a variety of challenges and obstacles for the GT 63 S to achieve its goals. One of my favorite sections – and one part that can be particularly cruel in highlighting the balance issues that a car might be facing – is the section on performance management. You enter the chicane at a fast and fast turn with a slight decrease in altitude after a climb. It's enough to upset the balance of the most skilled cars, but the 4MATIC + all-wheel drive and the steering of the Mercedes-AMG rear wheels have gnawed at it without a problem.

At lower speeds, the rear wheels rotate in the opposite direction to the front, which reduces the turning radius. It is particularly useful for maneuvering in narrow car parks. At higher speeds, the rear wheels turn in tandem with the front, which adds to the feeling of stability and helps the GT 63 S feel stable and bend quickly in tight turns. Germanic perfection is not imposed on you: in race mode, you can always cause a drift through the slaloms, even if I have never felt anything but the control.

The other option AMG GT 4 Door: GT 53

One could say that it is easier to create a very expensive performance car without compromising than it is to consider a more affordable version that is not limited to track skills. With that in mind, I focused my attention on the benefits of Mercedes-AMG. other Option GT 4 Door, the new GT 53. Gets a six-cylinder in-line 3.0-liter, producing 367 horsepower on the GT 43 and 435 horsepower on the GT 53 model. Much less than the GT 63, yes, but you pay much less: another option is for GT 43 to go under $ 100,000, while GT 53 will be around $ 130,000.

Of course, these prices are still not "cheap". We do not know if GT 43 will do it either. Yet in the context of the rest of the performance market, it could be good business.

The obvious competition is the Porsche Panamera Turbo and the BMW M6 Gran Coupé. The fastback silhouette of the Mercedes looks surprisingly like the improved Porsche Panamera 2019. However, the Mercedes has a more aggressive fascia than the BMW and the Porsche. I think the Audi RS7 could also look over his shoulder.

Then there is the Mercedes CLS coupe. On the basis of appearance alone, it would be easy to assume that the GT 4-Door is based on the CLS platform, but you are mistaken. In fact, the new car uses the MRA architecture of the current E Class sedan. For this, the Mercedes-AMG team adds an elegant and sporty body, with a ridiculously inclined windshield and a low silhouette to create the 4-door GT. Squint, and the coupe proportions promised by the name are all present, including the long hood and the tilted rear profile at the rear. Mercedes avoids too many CLS comparisons with its oversized grille with vertical bars and its AIRPANEL air control system in the front apron, as well as the thick rear diffuser.

The GT 43 and GT 53 do not have a "V" to put their turbochargers on, but they have a lightweight hybrid system. EQ Boost uses an electric motor that also serves as alternator and starter. Mounted between the engine and transmission, it powers the AMG's 48-volt electrical system, but can also help boost near-term horsepower and torque by approximately 22 horsepower and 184 foot-pounds.

It works in tandem with the two-stage turbocharger, with the mild hybrid system that fires when the turbo launches. The result is an immediate torque boost with no noticeable turbo lag, as well as a raw rotational speed suitable for the AMG badge. In the GT 53, it pushes the maximum torque to 384 lb-ft and helps provide a 0 to 60 mph time in 4.5 seconds. It's a good time for a large family sedan. The maximum speed reaches 177 mph.

With all that puts the emphasis on power and speed, it seems a bit perverse that one of the biggest selling points of the Mercedes-AMG GT 53 is its fuel consumption. Even with the standard 4MATIC + AWD system and the AMG SPEEDSHIFT 9G automatic transmission, it is expected to handle around 25 mpg in the combined cycle. It's not bad at all for the segment, even though American cars will only be able to sit four, not five.

Away from the track, a striking cruiser

As nice as it may be to stay on the track all day, finally, the Mercedes-AMG GT 4-Door 2019 has to venture on more asphalt. It is the AMG dynamic selection function that is responsible for aligning the beast, adjusting the behavior of the engine, transmission, suspension and exhaust accordingly. By tilting towards comfort, the suspension becomes noticeably softer and the exhaust system flaps are closed, tempering the soundtrack unless you are firmly leaning on the throttle. AMG Dynamics handling is adjusted in basic mode, giving priority to higher yaw damping in flatter turns.

For a little more enthusiasm, there is the sport mode. Transit times are reduced and engine tuning and throttle response are more aggressive. The ECO start / stop function is also disabled, while the AMG Dynamics control switches to Advance mode to balance driving, handling and agility. A stiffer suspension still sacrifices the ride comfort in the name of the body roll, not to mention the improved cornering handling.

The end result is that road performance is as good – if not better – than you would imagine for a four-door sports car. This is a significant differentiator between the AMG 63 S and C63 S GTs. The minimal road and wind noise, combined with smooth driving, leaves an impression of luxury, whether you're driving or driving. be driving.

Verdict

If you are in the enviable position of shopping for a powerful four-door sedan, both at home and in the transport of people on the move for a day on the track, it is worth considering the latest Mercedes offer. Although rear-drive fans may still want to turn to the AMG C 63 S, anyone with the Porsche Panamera Gran Turismo or the BMW M6 Gran Coupé would miss out on this new super-four-door AMG. After all, he is as aggressive as he is in the air.
